Predicting a 21cm AGN reionization signal
Can we detect the signature of an AGN reionization?

It turns out that supernovae, much like beans, are a magical fruit that can make galaxies release an outflow of gas. Also, simulations are complicated.
Accretion instabilities driving violent outcome of a merging binary, and its observable signatures.
The authors of today’s paper created simulated galaxies, for which true properties are known. They then used synthetic observations to compare the true answers to the values observers would expect to recover.
Star formation and supernova explosions play an important role in galaxy formation and evolution, in a process known as feedback. Today’s astrobite discusses how modifying the amount of feedback from supernova explosions affects the properties of the disc of a Milky Way galaxy, and how it affects the hot, gaseous halo surrounding massive galaxies.
Supermassive black holes (SMBH) likely exist at the center of every massive galaxy in our universe. How these million to billion solar mass beasts form is not well understood. The authors in today’s astrobite examine the possibility of the direct collapse of massive gas clouds to form SMBH seeds in a computer simulation of a galaxy merger.
