The SPT-Chandra BCG Spectroscopic Survey I: Evolution of the Entropy Threshold for Cooling and Feedback in Galaxy Clusters Over the Last 10 Gyr

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Michael S. Calzadilla, Michael McDonald, Bradford A. Benson, Lindsey E. Bleem, Judith H. Croston | Summary: We present a multi-wavelength study of the brightest cluster galaxies (BCGs) in a sample of the 95 most massive galaxy clusters selected from South Pole Telescope (SPT) Sunyaev-Zeldovich (SZ) survey. […]

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 […]

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 […]
