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. […]

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 […]

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 […]

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 […]

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 […]

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov, Nickolay Y. Gnedin, | Summary: We use a suite of hydrodynamics simulations of the interstellar medium (ISM) within a galactic disk, which include radiative transfer, a non-equilibrium model of molecular hydrogen, and a realistic model for star formation […]

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 […]

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Yue Pan, Andrey Kravtsov, , , | Summary: We investigate the impact of bursty star formation on several galaxy scaling relations of dwarf galaxies using the $texttt{GRUMPY}$ galaxy formation model. While this model reproduces the star formation rate (SFR)-stellar mass, stellar mass-gas mass, and stellar mass-metallicity relations, […]
