Counterparts to Gravitational Wave Events: Very Important Needles in a Very Large Haystack
Detecting electromagnetic and gravitational signals from a single astrophysical event will be revolutionary, but how do we find the former when we don’t know exactly where the latter is?
Stuff Between the Stars: Gas, Dust, and… Asteroids?
Interstellar space should be littered with debris ejected during the formation of planetary systems—but how much? Engelhardt et al. use solar system surveys and simulations to place an upper limit on the number density of asteroids and comets roaming the Milky Way without a parent star.
A Cosmic Beach Getaway
Some planets have atmospheres, and some don’t. What gives?
Same ol’ same ol’? Galaxy Clusters across Cosmic Time
X-ray studies of galaxy clusters tell us how the extremely hot gas is distributed within these gigantic structures. Looking at these clusters across different redshifts, what does one find?
