Investigating the Impact of Supernova Feedback on Satellites in Elliptical Galaxies
Sumi Kim, Ena Choi, Amanda C. N. Quirk +4
We investigate the influence of supernova (SN) feedback on the satellites of elliptical host galaxies using hydrodynamic simulations. Utilizing a modified version of the GADGET-3 c…

Galactic disc heating by density granulation in fuzzy dark matter simulations
Hsun-Yeong Yang, Barry T. Chiang, Guan-Ming Su +3
Fuzzy dark matter (FDM), an attractive dark matter candidate comprising ultralight bosons (axions) with a particle mass eV, is motivated by the small-scale challe…

The Origins of Gas Accreted by Supermassive Black Holes: the Importance of Recycled Gas
Ena Choi, Rachel S. Somerville, Jeremiah P. Ostriker +2
We investigate the fueling mechanisms of supermassive black holes (SMBHs) by analyzing ten zoom-in cosmological simulations of massive galaxies, with stellar masses $10^{11-12} M_{…
