The origin of the dust extinction curve in milky way-like galaxies
(Oxford University Press, 2021)
We develop a cosmological model for the evolution of dust grains in galaxies with a distribution of sizes in order to understand the origin of the Milky Way dust extinction curve. Our model considers the formation of active ...
Anomalous gas in ESO 149-G003: A MeerKAT-16 view
(Oxford University Press, 2021)
ESO 149-G003 is a close-by, isolated dwarf irregular galaxy. Previous observations with the ATCA indicated the presence of anomalous neutral hydrogen (H I) deviating from the kinematics of a regularly rotating disc. We ...
The infrared-radio correlation of star-forming galaxies is strongly M∗-dependent but nearly redshift-invariant since z ∼4
(EDP Sciences, 2021)
Over the past decade, several works have used the ratio between total (rest 8-1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (qIR), often referred to as the infrared-radio correlation (IRRC), ...
An ALMA/NOEMA survey of the molecular gas properties of high-redshift star-forming galaxies
(Oxford University Press, 2021)
We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We detect 12CO (Jup = 2-5) emission lines in 50 sources, and [C ...
HELP: The Herschel Extragalactic Legacy Project
(Oxford University Press, 2021)
We present the Herschel Extragalactic Legacy Project (HELP). This project collates, curates, homogenizes and creates derived data products for most of the premium multiwavelength extragalactic data sets. The sky boundaries ...
The redshift evolution of the baryonic Tully-Fisher relation in SIMBA
(Oxford university press, 2021)
The baryonic Tully–Fisher relation (BTFR) is an important tool for constraining galaxy evolution models. As 21-cm HI emission
studies have been largely restricted to low redshifts, the redshift evolution of the BTFR is ...
A critical look at the mass-metallicity-star formation rate relation in the local universe. I. An improved analysis framework and confounding systematics
(Institute of Physics Publishing, 2014)
It has been proposed that the (stellar) mass-(gas) metallicity relation of galaxies exhibits a secondary dependence on star formation rate (SFR), and that the resulting M∗-Z-SFR relation may be redshift-invariant, i.e., ...
MIGHTEE-H I: the first MeerKAT H I mass function from an untargeted interferometric survey
(Oxford University Press, 2023)
We present the first measurement of the H I mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MeerKAT International GigaHertz Tiered Extragalactic Exploration (MIGHTEE) Survey Early ...
Simba-c: the evolution of the thermal and chemical properties in the intragroup medium
(Oxford University Press, 2024)
The newly updated GIZMO and Simba based simulation, Simba-C, with its new stellar feedback, chemical enrichment, and recalibrated AGN feedback, allows for a detailed study of the intragroup medium X-ray properties. We ...
