Constraining Dark matter annihilation with Dark Energy Survey Y3 LSBG sample

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, , | Summary: To reveal natures of the dark matter (DM) particles, a gamma-ray signal produced in annihilation processes of DM into the standard model particles has been one of the major probes. The cross-correlation between highly DM dominated structures, […]

Cold Gas in Massive Galaxies as A Critical Test of Black Hole Feedback Models

Kavli Affiliate: Yingjie Peng | First 5 Authors: Jingjing Shi, Yingjie Peng, Benedikt Diemer, Adam R. H. Stevens, Annalisa Pillepich | Summary: Black hole feedback has been widely implemented as the key recipe to quench star formation in massive galaxies in modern semi-analytic models and hydrodynamical simulations. As the theoretical details surrounding the accretion and […]
