How to use gravitational waves to test if Einstein was right
The quest for the true nature of gravity continues! Can gravitational waves help us find the right answer? Today’s paper describes how this could work.
Growing a Galaxy
Today’s paper puts simulation-based theories to the test as we look at some of the most massive disk galaxies and find out how they grew to their enormous sizes!
#BlackInAstro Experiences: Dr. Ronald Gamble
As part of our #BlackInAstro series for Black History Month, we interview Dr. Ronald Gamble, a theoretical astrophysicist at NASA Goddard Space Flight Center!
A home has secrets too…
We don’t talk about accretion disks enough, but they hide so much physics in them! The authors of today’s paper try to understand which physical effect wins in circumbinary disks!
HEAVY, BUT NOT METAL: Could Metal-Free Stars be the Source of Massive Black Hole Mergers?
In today’s paper, the authors test the theory that the earliest, metal-poorest stars are the primary source of binary black hole mergers.
