The Cosmic Ultraviolet Baryon Survey (CUBS) IV: The Complex Multiphase Circumgalactic Medium as Revealed by Partial Lyman Limit Systems

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Thomas J. Cooper, Gwen C. Rudie, Hsiao-Wen Chen, Sean D. Johnson, Fakhri S. Zahedy | Summary: We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density $N_mathrm{H,I}approx(1-3)times10^{16},mathrm{cm}^{-2}$ discovered at $z=0.5$ in the Cosmic Ultraviolet Baryon Survey (CUBS). Available far-ultraviolet […]

Measurement of the Relativistic Sunyaev-Zeldovich Corrections in RX J1347.5-1145

Kavli Affiliate: Adam B. Mantz | First 5 Authors: Victoria Butler, Richard M. Feder, Tansu Daylan, Adam B. Mantz, Dale Mercado | Summary: We present a measurement of the relativistic corrections to the thermal Sunyaev-Zel’dovich (SZ) effect spectrum, the rSZ effect, toward the massive galaxy cluster RX J1347.5-1145 by combining sub-mm images from Herschel-SPIRE with […]

An axion dark matter-induced echo of supernova remnants

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Yitian Sun, Katelin Schutz, Anjali Nambrath, Calvin Leung, Kiyoshi Masui | Summary: Axions are a theoretically promising dark matter (DM) candidate. In the presence of radiation from bright astrophysical sources at radio frequencies, nonrelativistic DM axions can undergo stimulated decay to two nearly back-to-back photons, meaning that […]

Measuring the Density Fields around Bright Quasars at $zsim 6$ with XQR-30 Spectra

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Anna-Christina Eilers, Sarah E. I. Bosman, Nickolay Y. Gnedin, Xiaohui Fan | Summary: Measuring the density of the intergalactic medium using quasar sightlines in the epoch of reionization is challenging due to the saturation of Lyman-$alpha$ absorption. Near a luminous quasar, however, the enhanced […]

Mass of the dynamically hot inner stellar halo predicts the ancient accreted stellar mass

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ling Zhu, Annalisa Pillepich, Glenn van de Ven, Ryan Leaman, Lars Hernquist | Summary: Galactic dynamical structures are fossil records of the assembly histories of galaxies. By analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical structure that we call the "hot inner stellar halo," […]

Constraints on small-scale primordial density fluctuation from cosmic microwave background through dark matter annihilation

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, Kazunori Nakayama, , | Summary: The cosmic microwave background (CMB) observation by the Planck satellite precisely determines primordial curvature fluctuations on larger scales than $mathcal O(1),mathrm{Mpc}$, while the small-scale curvature fluctuation is still less constrained. The constraint on small-scale fluctuations is highly improved […]
