Emergence of the Temperature-Density Relation in the Low Density Intergalactic Medium

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Alexandra Wells, David Robinson, Camille Avestruz, Nickolay Y. Gnedin, | Summary: We examine the evolution of the phase diagram of the low-density intergalactic medium (IGM) during the Epoch of Reionization in simulation boxes with varying reionization histories from the Cosmic Reionization on Computers project. The PDF […]

A Population of Short-duration Gamma-ray Bursts with Dwarf Host Galaxies

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Anya E. Nugent, Wen-fai Fong, Cristian Castrejon, Joel Leja, Michael Zevin | Summary: We present a population of 11 of the faintest ($> 25.5$ AB mag) short gamma-ray burst (GRB) host galaxies. We model their sparse available observations using the stellar population inference code Prospector-$beta$ and […]

Exploring the Dependence of Gas Cooling and Heating Functions on the Incident Radiation Field with Machine Learning

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: David Robinson, Camille Avestruz, Nickolay Y. Gnedin, , | Summary: Gas cooling and heating functions play a crucial role in galaxy formation. But, it is computationally expensive to exactly compute these functions in the presence of an incident radiation field. These computations can be greatly sped […]

Modelling Stochastic Star Formation History of Dwarf Galaxies in GRUMPY

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Yue Pan, Andrey Kravtsov, , , | Summary: We investigate the impact of bursty star formation on several galaxy scaling relations of dwarf galaxies using the $texttt{GRUMPY}$ galaxy formation model. While this model reproduces the star formation rate (SFR)-stellar mass, stellar mass-gas mass, and stellar mass-metallicity relations, […]
