Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen, Tommaso Treu, Michele Cappellari | Summary: Strong-lensing time delays enable measurement of the Hubble constant ($H_{0}$) independently of other traditional methods. The main limitation to the precision of time-delay cosmography is mass-sheet degeneracy (MSD). Some of the […]

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Bruce Edelman, Michael Zevin, Maya Fishbach, Jose María Ezquiaga | Summary: Several features in the mass spectrum of merging binary black holes (BBHs) have been identified using data from the Third Gravitational Wave Transient Catalog (GWTC-3). These features are of particular interest as […]

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Megan Masterson, Michael McDonald, Behzad Ansarinejad, Matthew Bayliss, Bradford A. Benson | Summary: We present a multi-wavelength analysis of the galaxy cluster SPT-CL J0607-4448 (SPT0607), which is one of the most distant clusters discovered by the South Pole Telescope (SPT) at $z=1.4010pm0.0028$. The high-redshift cluster shows […]

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Jiawen Fan, Hanjue Zhu, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Lyman Limit Systems (LLSs) are dense hydrogen clouds with high enough HI column densities ($N_{rm HI}$) to absorb Lyman continuum photons emitted from distant quasars. Their high column densities imply an origin in dense environments; […]
