Guide to ΛCDM
In this Guide, we breakdown one of the most important models in astrophysics: the ΛCDM model of cosmology!
Over the Limit: Accretion and Feedback of Early Black Holes
Merry Christmas! In today’s bite, learn how simulations of black hole accretion and feedback are informing our understanding of the evolution of the earliest black holes.
Big Black Holes in Little Galaxies
Active galactic nuclei are commonly observed in large galaxies, but what about small galaxies? Today’s paper explores the effects of the universe’s largest and loudest black holes in the universe’s smallest galaxies.
Heavy Metal: Actinides from Compact Object Mergers
How are some of the heaviest elements on the periodic table created? Today’s authors look at how mergers between black holes and neutron stars could form these heavy metals!
Weight Gain: Growing Little Black Holes in the Early Universe
Astronomers are actively researching how massive black holes arise in the early universe. Is it possible for small black holes to grow fast enough to become one of these supermassive black holes? Today’s authors think there’s a chance!
