Shaken and Stirred: Putting the Local Group on a weighing scale.
The “timing argument” overestimates the total mass of the local group by oversimplifying it to a two body problem, a new study explore how the complex merger history of objects in the group affect its mass estimates.
Stay tuned to Radio YZ Ceti: Isn’t that a magnetic conversation between star and planet?
Astronomers have tuned their radio telescopes to YZ Ceti, and it might be crackling with a magnetic conversation of a star and its planet. Is this a breakthrough detection, or just stellar noise playing tricks on us?
Observing the Universe’s Teenage Angst with Dropout Galaxies and CMB Lensing
In today’s bite, we explore a new method for studying how structure grows during the Universe’s formative teenage years, using rebellious dropout galaxies and peer-pressured CMB photons.
