A UBC Okanagan-led research project has given a group of international scientists their clearest view yet of the Milky Way’s magnetic field, revealing that it is far more complex than previously believed.

Dr. Alex Hill, Assistant Professor in the Irving K. Barber Faculty of Science at UBCO, specializes in radio astronomy. Working at the Dominion Radio Astrophysical Observatory (DRAO), near Penticton, his team used data from the DRAO 15-metre telescope to complete the first broadband map of Faraday rotation, a phenomenon that scientists use to track magnetic fields across the northern sky.

The dataset, known as Dominion Radio Astrophysical Observatory GMIMS of the northern sky (DRAGONS) and led by former UBCO postdoctoral researcher Dr. Anna Ordog, captures polarized radio emissions across a wide range of frequencies, allowing astronomers to see magnetic structures that were previously invisible. This research is part of a larger initiative called the Global Magneto-Ionic Medium Survey (GMIMS), initiated by Dr. Tom Landecker, an astronomer at DRAO and adjunct professor at both UBCO and the University of Calgary.

“With our new dataset, we can look at the polarized emissions from within the galaxy itself, and we see that the magnetic field has a lot of structure to it,” Dr. Ordog explains. “DRAGONS is the first to show this level of complexity on such large spatial scales and across the entire northern sky.”

The work builds on a theoretical insight first proposed in 1966, which showed that polarized radio waves observed at many frequencies enable measurements of the three-dimensional structure of the Milky Way’s magnetic field. At the time, the technology needed to observe this effect across wide frequency ranges did not exist. Modern broadband telescopes, including the DRAO 15m telescope, have made this research possible.

The project was the first scientific use of the 15m telescope, which DRAO originally built as a prototype antenna for the SKA—a large radio telescope currently under construction in Southern Africa and Western Australia. Dr. Ordog led the setup for the DRAGONS project, supported by five students from UBCO and the University of Calgary, along with the expertise of DRAO engineers and technologists.

“The 15m is the ideal instrument for this all-sky survey of large-scale magnetized structures—it can scan rapidly, effectively ‘painting’ a map of the polarized sky in just six months,” she says. “Having the 15m so close to UBCO allowed students to contribute to hands-on testing in preparation for the survey.”

UBCO students analyzed “first light” signals from the instrument, developed algorithms to identify human-made radio interference and assessed the survey data quality.

The study, recently published in The Astrophysical Journal Supplement Series, tracks how polarized radio waves twist as they travel through the galaxy, revealing the strength, structure and direction of magnetic fields along the line of sight. This survey shows that more than half the sky contains complex magnetic structures rather than simple, uniform fields.

Dr. Landecker says the biggest surprise for the researchers was just how much of the sky is what is known as “Faraday complex”.

“With our new dataset, we can look at the polarized emission from within the galaxy itself, and we can see that the magnetic field has much more structure to it than we could detect with earlier observation methods,” says Dr. Landecker, who is also the leader of a larger effort to map magnetic fields in three dimensions and an astronomer emeritus at DRAO.

“DRAGONS is like a compass, telling us how matter and magnetic fields in the galaxy are organized and how the magnetic field interacts with bubbles created by supernova explosions, spiral arms and other parts of the galaxy in ways that have never been possible before.”

Magnetic fields shape how stars are formed and how galaxies evolve, explains Dr. Hill.

“For decades, we could only measure the Milky Way’s magnetic field in a very averaged, simplified way,” says Dr. Hill. “But its magnetic field is an important piece of the puzzle when it comes to understanding how the universe and everything in it operates and came into being.”

Already, the DRAGONS data have been used in a study of the mysterious large-scale reversal in the galactic magnetic field. This latest study was led by University of Calgary doctoral student Rebecca Booth and published in an accompanying paper in The Astrophysical Journal this week. This is a good example of how the dataset will provide opportunities for continued research in this field, says Dr. Ordog.

“DRAGONS is part of a new generation of radio surveys that allow scientists to map the Milky Way’s three-dimensional magnetic field structure in the space between the stars,” she adds. “It is an important Canadian contribution to the global astronomical community.”

A satellite image representing remote sensing technology. UBCO’s new segmentation method helps researchers detect wildfire sparks and other small-scale changes in satellite data.

A group of UBC Okanagan students has helped create technology that could improve how doctors and scientists detect everything from tumours to wildfires.

Working under the guidance of Associate Professor Xiaoping Shi from UBCO’s Department of Computer Science, Mathematics, Physics and Statistics, the students designed and tested a system called an adaptive multiple change point energy-based model segmentation (MEBS).

This method uses advanced mathematics to pick out important details in complex or noisy images, the kind that often confuse existing detection methods.

“This project gave us a chance to work on something that can make a real difference,” says Jiatao Zhong, a UBCO master’s student and lead author of the study. “It’s exciting to know that what we built could help doctors spot illnesses sooner and help scientists track wildfires more effectively.”

The work, recently published in Scientific Reports, shows that MEBS can help health professionals find signs of disease in medical scans, assist plant scientists in tracking cell growth and give wildfire monitors a faster way to identify hotspots from space. 

“Our students played a big role in building and refining this model, and they had a chance to apply it to real-world problems,” says Dr. Shi. “The skills they gained in programming, data analysis and applied mathematics will give them an edge in their future careers.”

The team’s research showed success across several key areas:

• In medical scans by detecting tumours and fluid buildup in X-rays and mammograms with greater clarity than standard tools.
• In wildfire monitoring by picking out small but critical sparks in satellite images, which can lead to faster response times.
• In biological research by helping scientists count and track cells in plant studies, important for agriculture and growth research.

Dr. Yuejiao Fu collaborated with Dr. Shi on the paper while the student team—Zhong, Shiyin Du, Canruo Shen, Yiting Chen, Medha Naidu and Min Gao—worked on tasks ranging from coding and testing to running experiments on medical and satellite images.

Together, they demonstrated that MEBS can do what many existing tools cannot: automatically adapt when an image does not follow typical patterns, improving accuracy without extra manual work. 

Most image tools use fixed rules that don’t always work in the real world. Medical scans and satellite images are often noisy or inconsistent.  

MEBS stands out because it adapts to the image itself—detecting subtle shifts and dividing complex visuals into useful sections. This leads to more accurate results for doctors, scientists and wildfire monitors alike. 

The project was supported by the Natural Sciences and Engineering Research Council of Canada and UBC Okanagan’s Office of the Vice-Principal, Research and Innovation.

Graduates toss their caps as their ceremony comes to a conclusion at one of three graduation ceremonies at UBCO Thursday.

When Liam Krebbers crossed the stage to receive his degree at UBC Okanagan’s final graduation ceremony today, it was a brand-new experience for him.

Like many of his classmates, Krebbers graduated high school in June 2020 at the height of the COVID-19 pandemic. It was a time of isolation, protective masks and cancelled or modified celebrations.

“I graduated high school during the time of online and physically distanced ceremonies,” says Krebbers.  “I walked across the stage in a nearly empty arena, 15 minutes apart from my friends. I’m very excited this year to be part of an actual graduation ceremony and I’m looking forward to graduating with all my friends.”

Krebbers was one of 2,400 graduates celebrated Thursday and Friday at UBCO—the largest number of graduating students since the university campus was established in 2005.

For many students, notes Dr. Lesley Cormack, UBCO’s Principal and Deputy Vice-Chancellor, it was their first opportunity to cross that stage in front of a jam-packed audience.

“We are incredibly excited to celebrate graduation every year, but this year is particularly meaningful as many of the students graduating did not have a traditional high school graduation due to the pandemic,” says Dr. Cormack. “Ceremonies like graduation provide opportunities for connection, signify our collective values and allow us to come together to celebrate the hard work that has gone into obtaining a UBC degree.”

Along with conferring more than 2,400 doctoral, master’s and undergraduate degrees, UBCO celebrated a number of top academic awards, teaching excellence awards and the conferring of seven Bachelor of Nsyilxcn Language Fluency (BNFL) degrees. This is the second cohort of students to graduate from the BNLF program, the first being last year after the degree program was introduced in accordance with UBC’s commitment to truth and reconciliation.

During graduation, UBCO also celebrated three people who have been instrumental in the growth of the campus and the community with honorary degrees.

Dr. Deborah Buszard, who served as Interim UBC President from 2022 to 2023, and UBCO’s Principal and Deputy Vice-Chancellor for eight years before that, was presented with a Doctor of Laws, honoris causa Thursday morning. Ian Cull, former UBCO Associate Vice-President, Students was also presented with a Doctor of Laws, honoris causa Thursday afternoon. Kelowna entrepreneur Ragwa Gopal, a leader in British Columbia’s tech and innovation community and founder of Accelerate Okanagan in 2012, was presented with a Doctor of Laws, honoris causa Friday morning.

Honorary degrees are awarded by universities to recognize people who have made substantial contributions to society at the provincial, national or international levels. Dr. Cormack noted all three honorary degree recipients have made a significant difference to the Okanagan region, the community and UBCO since it first opened 19 years ago.

In all, six ceremonies took place yesterday and today, and the students of 2024 were celebrated loudly and proudly by their families, fellow students as well as UBCO faculty and staff.

“I extend my heartfelt congratulations to the UBC Okanagan Class of 2024 for their hard work, perseverance and determination,” adds Dr. Cormack. “They are going out into a world as change makers and it desperately needs them. We are proud of them and can’t wait to see what they achieve.”

Researchers have created a physical theory encompassing both quantum mechanics and general relativity which can help scientists construct a complete theory of how the universe works. Photo credit: Bryan Goff on Unsplash

In a new study published in Nature Reviews Physics, an international research team, including UBC Okanagan’s Dr. Mir Faizal, has ventured into uncharted territories for physics by trying to blend Einstein’s theory of general relativity with quantum mechanics. This innovative approach paves the way for new insights into the nature of space and time.

General relativity explains the structure of the universe at a very large scale—the scale of galaxies. However, the universe at a small scale, such as atomic physics is described by quantum mechanics.

It has not been possible to construct a complete theory of the universe, encompassing both quantum mechanics and general relativity, explains Dr. Faizal. Physicists have long argued that any such theory cannot emerge from space and time.

This mind-bending observation of space and time emerging from something that is neither space nor time challenges our conventional understanding of the universe, he explains. This is the reason why blending general relativity with quantum mechanics is so difficult Dr. Faizal adds.

However, these researchers point out that this emergence can be understood using water as an analogy.

“Water is made up of individual molecules,” explains Dr. Faizal, an Adjunct Professor of Mathematics and Physics with UBCO’s Irving K. Barber Faculty of Science. “Water also forms shapes like a whirlpool, when it is drained. However, at the scale of individual molecules no such shape exists, and this geometric shape is an emergent structure. Similarly, the geometrical shape of space and time is emergent.”

This analogy helps to explain how space and time can emerge from a theory which does not exist within the confines of either.

“Any attempt to construct quantum gravity seems to indicate that spacetime would emerge from something that exists neither in space nor in time. So, we are now looking at a physical theory which is beyond space and time,” adds Dr. Faizal, who is also the Scientific Director of the Canadian Quantum Research Center.

Researchers now have used moving fluids to understand the emergence of space and time. This allows them to further investigate some deep questions related to the quantum physics of black holes. They hope this will foster collaboration between researchers from different disciplines to further the understanding of these complex phenomena.

The global research team includes Dr. Samuel Braunstein from the University of York in the UK, Dr. Lawrence Krauss, Dr. Francesco Marino from the National Institute of Optics in Italy and Dr. Naveed Shah from the Jamia Millia Islamia University in India.
