ALMACAL XIV: X-Shooter Spectroscopy, Infrared Properties and Radio SEDs of Calibrators

Simon Weng, Elaine M. Sadler, Emily Kerrison +8

The ALMACAL-22 survey includes over 2700 hours of observations of ALMA phase and amplitude calibrators, spanning frequencies from 84 to 950 GHz across bands 3 to 10. In total, 687…

Searching for cold gas traced by MgII quasar absorbers in massive X-ray-selected galaxy clusters

A. Y. Fresco, C. Peroux, A. Merloni +3

Almost 50% of galaxies in the local Universe are in clusters or groups coexisting with both hot and cold gas components. In the present study, we observationally probed the cold-ga…

MUSE-ALMA Haloes IX: Morphologies and Stellar Properties of Gas-rich Galaxies

Arjun Karki, Varsha P. Kulkarni, Simon Weng +15

Understanding how galaxies interact with the circumgalactic medium (CGM) requires determining how galaxies morphological and stellar properties correlate with their CGM properties.…

MUSE-ALMA Halos XI: Gas flows in the circumgalactic medium

Simon Weng, Céline Péroux, Arjun Karki +12

The flow of gas into and out of galaxies leaves traces in the circumgalactic medium which can then be studied using absorption lines towards background quasars. We analyse 27 log(N…

MUSE-ALMA Haloes VIII: Statistical Study of Circumgalactic Medium Gas

Simon Weng, Céline Péroux, Arjun Karki +15

The distribution of gas and metals in the circumgalactic medium (CGM) plays a critical role in how galaxies evolve. The MUSE-ALMA Halos survey combines MUSE, ALMA and HST observati…

MUSE-ALMA Haloes VII: Survey Science Goals & Design, Data Processing and Final Catalogues

Céline Péroux, Simon Weng, Arjun Karki +16

The gas cycling in the circumgalactic regions of galaxies is known to be multi-phase. The MUSE-ALMA Haloes survey gathers a large multi-wavelength observational sample of absorptio…

ALMACAL IX: multi-band ALMA survey for dusty star-forming galaxies and the resolved fractions of the cosmic infrared background

Jianhang Chen, R. J. Ivison, Martin A. Zwaan +8

Wide, deep, blind continuum surveys at submillimetre/millimetre (submm/mm) wavelengths are required to provide a full inventory of the dusty, distant Universe. However, conducting…

Tracing the 10K Warm-Hot Intergalactic Medium with UV absorption lines

A. Fresco, C. Péroux, A. Merloni +2

Today, the majority of the cosmic baryons in the Universe are not observed directly, leading to an issue of "missing baryons" at low redshift. Cosmological hydrodynamical simulatio…
