HALOGAS: Strong Constraints on the Neutral Gas Reservoir and Accretion Rate in Nearby Spiral Galaxies
P. Kamphuis, E. Jütte, G. H. Heald +11
Galaxies in the local Universe are thought to require ongoing replenishment of their gas reservoir in order to maintain the observed star formation rates. Cosmological simulations…
Searching for axion dark matter with MeerKAT Radio Telescope
Yun-Fan Zhou, Nick Houston, Gyula I. G. Jozsa +11
Axions provide a natural and well-motivated dark matter candidate, with the capability to convert directly to photons in the presence of an electromagnetic field. A particularly co…
Connecting MeerKAT radio continuum properties to GAMA optical emission-line and WISE mid-infrared activity
H. F. M. Yao, M. E. Cluver, T. H. Jarrett +10
The identification of AGN in large surveys has been hampered by seemingly discordant classifications arising from differing diagnostic methods, usually tracing distinct processes s…
First release of Apertif imaging survey data
Elizabeth A. K. Adams, B. Adebahr, W. J. G. de Blok +56
(Abridged) Apertif is a phased-array feed system for WSRT, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated survey program started on 1 July 2019, with th…
Mapping HI 21-cm in the Klemola 31 group at z = 0.029: emission and absorption towards PKS2020-370
E. K. Maina, Abhisek Mohapatra, G. I. G. Jozsa +11
We present MeerKAT Absorption Line Survey (MALS) observations of the HI gas in the Klemola31 galaxy group (), located along the line of sight to the radio-loud quasar PKS2…
Emergence of a new HI 21-cm absorption component at z~1.1726 towards the gamma-ray blazar PKS~2355-106
Raghunathan Srianand, Neeraj Gupta, Patrick Petitjean +12
We report the emergence of a new HI 21-cm absorption at z_abs = 1.172635 in the damped Lyman-alpha absorber (DLA) towards the gamma-ray blazar PKS 2355-106 (z_em~1.639) using scien…
