OzDES Reverberation Mapping Program: CIV lags from six years of data

A. Penton, H. McDougall, T. M. Davis +52

The paper reports 29 successful CIV reverberation time‑lag measurements for high‑redshift active galactic nuclei from the OzDES survey, derives black‑hole masses of 0.8–1.3 billion…

Inferring the mass of the circumgalactic medium using X-ray resonant scattering

Nhut Truong, Maxim Markevitch, Dylan Nelson +1

The circumgalactic medium (CGM) regulates galaxy growth and retains the imprint of feedback from supernovae and supermassive black holes. However, the bulk of the hot CGM produces…

Initial Investigations of the Outskirts of XLSSC 122

Eleanore. B. Todd, Jon. P. Willis, Rebecca. E. A. Canning +7

We investigate the redshift 1.98 galaxy cluster XLSSC 122 using the Hubble Space Telescope (HST) from the core of the cluster out to 3 Mpc, a scale equivalent to 10 times the R500…

The DESI Y1 RR Lyrae catalog I: Empirical modeling of the cyclic variation of spectroscopic properties and a chemodynamical analysis of the outer halo

Gustavo E. Medina, Ting S. Li, Sergey E. Koposov +44

We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6,240 RRLs…

Revealing the cold skeleton of the Magellanic Clouds and the Magellanic Bridge with ASKAP

James Dempsey, N. M. McClure-Griffiths, Antoine Marchal +14

We present the GASKAP-HI pilot absorption survey of neutral hydrogen (HI) in the Magellanic system. This survey provides 3219 sightlines across the Large (LMC) and Small Magellanic…

Itô tracers: continuous-trajectory Lagrangian particles for Eulerian hydrodynamics

Eric R. Moseley, R. Teyssier, Tom Abel

Lagrangian tracer particles have long been used to track the history of individual gas parcels in hydrodynamical codes. Particles advected by the cell-centered velocity carry no re…
