Professor Xander Tielens, a chemical physicist and self-described moon child, studies molecules in the interstellar medium as a tool for understanding everything from galaxy evolution to the origin of life. Learn more at his plenary talk at #AAS234.
Professor Yacine Ali-Haïmoud studies the theory behind our astrophysical observations, from primordial black holes to organic compounds in the interstellar medium. Learn more at his keynote at #AAS234.
Wiggly rulers don’t seem like good measuring devices, but Velocity-induced Acoustic Oscillations might be an exception.
The local gravitational tides are really good at connecting the properties of dark matter halos to the cosmic web.
Cosmologists revisit an idea for addressing the Hubble tension: that a local void is messing with our measurements along the cosmic distance ladder.
