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; […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Yunchong Zhang, Viraj Manwadkar, Michael D. Gladders, Gourav Khullar, Håkon Dahle | Summary: We report the discovery of five bright strong gravitationally lensed galaxies at $3 < z < 4$: COOLJ0101$+$2055 ($z = 3.459$), COOLJ0104$-$0757 ($z = 3.480$), COOLJ0145$+$1018 ($z = 3.310$), COOLJ0516$-$2208 ($z = 3.549$), […]
Philip F. Hopkins, Ethan O. Nadler, Michael Y. Grudic, Xuejian Shen, Isabel Sands | Summary: [[{“value”:”Modeling self-gravity of collisionless fluids (e.g. ensembles of dark matter, stars, black holes, dust, planetary bodies) in simulations is challenging and requires some force softening. It is often desirable to allow softenings to evolve adaptively, in any high-dynamic range simulation, […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: L. Balkenhol, D. Dutcher, A. Spurio Mancini, A. Doussot, K. Benabed | Summary: We present a sample-variance-limited measurement of the temperature power spectrum ($TT$) of the cosmic microwave background (CMB) using observations of a $sim! 1500 ,mathrm{deg}^2$ field made by SPT-3G in 2018. We report multifrequency power […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kielan K. W. Hoch, Quinn M. Konopacky, Christopher A. Theissen, Jean-Baptiste Ruffio, Travis S. Barman | Summary: The carbon-to-oxygen (C/O) ratio in an exoplanet atmosphere has been suggested as a potential diagnostic of planet formation. Now that a number of exoplanets have measured C/O ratios, it is […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Christian Boyd, Yonit Hochberg, Yonatan Kahn, Eric David Kramer, Noah Kurinsky | Summary: Direct detection for sub-GeV dark matter is developing rapidly, with many novel experimental ideas and theoretical methods emerging. In this work, we extend the dielectric formalism for dark matter scattering to incorporate anisotropic material […]
