Armenian physicist, professor of Simon Fraser University of Vancouver (SFU), and foreign employee of Byurakan Observatory Levon Pogosian has won the 2021 Buchalter Cosmology Prize. Pogosian and his collaborator Karsten Jedamzik from the University of Montpellier will share the First Prize award for their research on relieving the Hubble tension with primordial magnetic fields․
The Hubble tension is one of cosmology’s greatest puzzles that concerns the apparent difference in the Hubble constant, or how fast the universe is expanding today, determined using different types of observations.
The Buchalter Cosmology Prize, established in 2014, recognizes “ground-breaking theoretical, observational, or experimental work in cosmology.”
This year’s winners were announced by the American Astronomical Society.
