Domain Adaptive Graph Neural Networks for Constraining Cosmological Parameters Across Multiple Data Sets

Kavli Affiliate: Brian Nord | First 5 Authors: Andrea Roncoli, Aleksandra Ćiprijanović, Maggie Voetberg, Francisco Villaescusa-Navarro, Brian Nord | Summary: Deep learning models have been shown to outperform methods that rely on summary statistics, like the power spectrum, in extracting information from complex cosmological data sets. However, due to differences in the subgrid physics implementation […]

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 […]
