The physical origins of gas in the circumgalactic medium using observationally-motivated TNG50 mocks
Simon Weng, Celine Peroux, Rahul Ramesh +5
Absorbers in the spectrum of background objects probe the circumgalactic medium (CGM) surrounding galaxies, but its physical properties remain unconstrained. We use the cosmologica…
An Hα view of galaxy build-up in the first 2 Gyr: luminosity functions at z~4-6.5 from NIRCam/grism spectroscopy
Alba Covelo-Paz, Emma Giovinazzo, Pascal A. Oesch +22
The Hα nebular emission line is an optimal tracer for recent star formation in galaxies. With the advent of JWST, this line has recently become observable at z>3 for the first tim…
The BarYon CYCLE Project (ByCycle): Identifying and Localizing MgII Metal Absorbers with Machine Learning
Roland Szakacs, Céline Péroux, Dylan Nelson +6
The upcoming ByCycle project on the VISTA/4MOST multi-object spectrograph will offer new prospects of using a massive sample of million high spectral resolution ( = 20,…
ALMACAL. XI. Over-densities as signposts to proto-clusters? A cautionary tale
Jianhang Chen, R. J. Ivison, Martin A. Zwaan +6
It may be unsurprising that the most common approach to finding proto-clusters is to search for over-densities of galaxies. Upgrades to submillimetre (submm) interferometers and th…
The Hα Luminosity Function of Galaxies at z {\sim} 4.5
Victoria Bollo, Valentino González, Mauro Stefanon +5
We present the Hα luminosity function (LF) derived from a large sample of Lyman break galaxies at z {\sim} 4.5 over the GOODS-South and North fields. This study makes use of the n…
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…
MUSE-ALMA Haloes XIII. Molecular gas in HI-selected galaxies
Victoria Bollo, Celine Peroux, Martin Zwaan +11
We present new results from the MUSE-ALMA Haloes survey, covering 79 galaxies associated with strong HI absorption at redshift about 0.5. Our ALMA Cycle 10 observations add 39 syst…
ALMACAL XII. Data characterisation and products
Victoria Bollo, Martin Zwaan, Celine Peroux +5
The ALMACAL survey is based on a database of reprocessed ALMA calibration scans suitable for scientific analysis, observed as part of regular PI observations. We present all the da…
ALMACAL XIII. Evolution of the CO luminosity function and the molecular gas mass density out to ~ 6
Victoria Bollo, Céline Péroux, Martin Zwaan +7
Cold molecular gas, largely traced by CO emission, is the primary fuel for star formation, making it essential for understanding galaxy evolution. ALMA has made significant progres…
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…
