The Atacama Cosmology Telescope: stellar mass growth in massive galaxy clusters from DR5 over the past 7 billion years

Damien C. Ragavan, Unnikrishnan Sureshkumar, Matt Hilton +8

We probe the stellar mass growth in a sample of 568 Sunyaev-Zel'dovich (SZ) selected galaxy clusters with masses greater than and redshifts…

Measuring the Temperature of Extremely Hot Shock-Heated Gas in the Major Merger MACS J0717.5+3745 With Relativistic Corrections to the Sunyaev-Zel'dovich Effect

Benjamin J. Vaughan, Jack Sayers, Locke Spencer +10

The conversion of gravitational potential to kinetic energy results in an intracluster medium (ICM) gas with a characteristic temperature near 10 keV in the most massive galaxy clu…

Hiding behind a curtain of dust: Gas and dust properties of an ultra-luminous strongly-lensed z = 3.75 galaxy behind the Milky Way disk

Belén Alcalde Pampliega, Kevin C. Harrington, Aristeidis Amvrosiadis +21

We present a detailed analysis of J154506, a strongly lensed submillimeter galaxy behind the Lupus-I molecular cloud, and characterisation of its physical properties using a combin…

The link between galaxy merger, radio jet expansion and molecular outflow in the ULIRG IRAS 00183-7111

Ilaria Ruffa, Marilena Spavone, Enrichetta Iodice +8

The ultraluminous infrared galaxy (ULIRG) IRAS 00183-7111 () is one of the three ULIRGs that are currently known to host an active galactic nucleus (AGN) with small-scale…

Simulating High-Velocity Clouds in the Observational Plane: An Initial Study with the Smith Cloud

Lori E. Porter, Matthew Abruzzo, Greg L. Bryan +3

High-velocity clouds (HVCs) may fuel future star formation in the Milky Way, but they must first survive their passage through the hot halo. While recent work has improved our unde…

Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters

Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14

We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…

Halfway to the Peak: ice absorption bands at with JWST MIRI/MRS

Anna Sajina, Alexandra Pope, Henrik Spoon +9

This paper presents the first combined detections of CO, CO, XCN and water ices beyond the local Universe. We find gas-phase CO in addition to the solid phase CO. Our source, S…

Backlighting extended gas halos around luminous red galaxies: kinematic Sunyaev-Zel'dovich effect from DESI Y1 x ACT

Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska +58

The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-…

Applying a star formation model calibrated on high-resolution interstellar medium simulations to cosmological simulations of galaxy formation

Jan D. Burger, Volker Springel, Eve C. Ostriker +11

Modern high-resolution simulations of the interstellar medium (ISM) have shown that key factors in governing star formation are the competing influences of radiative dissipation, p…
