Reviving MeV-GeV Indirect Detection with Inelastic Dark Matter

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Asher Berlin, Gordan Krnjaic, Elena Pinetti, , | Summary: Thermal relic dark matter below $sim 10 text{GeV}$ is excluded by cosmic microwave background data if its annihilation to visible particles is unsuppressed near the epoch of recombination. Usual model-building measures to avoid this bound involve kinematically suppressing […]

Impact of Property Covariance on Cluster Weak lensing Scaling Relations

Kavli Affiliate: Joshua Frieman | First 5 Authors: Zhuowen Zhang, Arya Farahi, Daisuke Nagai, Erwin T. Lau, Joshua Frieman | Summary: We present an investigation into a hitherto unexplored systematic that affects the accuracy of galaxy cluster mass estimates with weak gravitational lensing. Specifically, we study the covariance between the weak lensing signal, $DeltaSigma$, and […]

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 […]
