Deblending the MIGHTEE-COSMOS survey with XID+: The resolved radio source counts to Jy

Eliab D. Malefahlo, Matt J. Jarvis, Mario G. Santos +9

Deep radio continuum surveys provide fundamental constraints on galaxy evolution, but source confusion limits sensitivity to the faintest sources. We present a complete framework f…

An independent estimate of H(z) at z = 0.5 from the stellar ages of brightest cluster galaxies

S. Ilani Loubser, Adebusola B. Alabi, Matt Hilton +6

Several cosmological observations (e.g., Cosmic Microwave Background (CMB), Supernovae Type Ia, and local distance ladder measurements such as Cepheids) have been used to measure t…

LADUMA: Discovery of a luminous OH megamaser at

Marcin Glowacki, Jordan D. Collier, Amir Kazemi-Moridani +65

In the local Universe, OH megamasers (OHMs) are detected almost exclusively in infrared-luminous galaxies, with a prevalence that increases with IR luminosity, suggesting that they…

Blind HI and OH absorption line search: first results with MALS and uGMRT processed using ARTIP

N. Gupta, P. Jagannathan, R. Srianand +32

We present details of the Automated Radio Telescope Imaging Pipeline (ARTIP) and results of a sensitive blind search for HI and OH absorbers at and , respectively. A…

The MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Survey

Matt J. Jarvis, A. R. Taylor, I. Agudo +54

The MIGHTEE large survey project will survey four of the most well-studied extragalactic deep fields, totalling 20 square degrees to Jy sensitivity at Giga-Hertz frequencies, as…

The MeerKAT Absorption Line Survey (MALS)

N. Gupta, R. Srianand, W. Baan +41

Deep galaxy surveys have revealed that the global star formation rate (SFR) density in the Universe peaks at 1 < z < 2 and sharply declines towards z = 0. But a clear picture of th…
