MALS discovery of a rare HI 21-cm absorber at : origin of the absorbing gas in powerful AGN
P. P. Deka, N. Gupta, H. W. Chen +14
We report a new, rare detection of HI 21-cm absorption associated with a quasar (only six known at ) here towards J2339-5523 at = 1.3531, discovered through the Mee…
Plausible association of distant late M dwarfs with low-frequency radio emission
A. J. Gloudemans, J. R. Callingham, K. J. Duncan +10
We present the serendipitous discovery of 8 distant ( 50 pc) late M dwarfs with plausible associated radio emission at 144 MHz. The M dwarf nature of our sources has been confir…
The MeerKAT Absorption Line Survey (MALS) data release I: Stokes I image catalogs at 1-1.4 GHz
P. P. Deka, N. Gupta, P. Jagannathan +24
The MeerKAT Absorption Line Survey (MALS) has observed 391 telescope pointings at L-band (900 - 1670 MHz) at . We present radio continuum images and a catalog of…
The cosmic radio dipole: Bayesian estimators on new and old radio surveys
J. D. Wagenveld, H-R. Klöckner, D. J. Schwarz
The cosmic radio dipole is an anisotropy in the number counts of radio sources, analogous to the dipole seen in the cosmic microwave background (CMB). Measurements of source counts…
The MeerKAT Absorption Line Survey: Homogeneous continuum catalogues towards a measurement of the cosmic radio dipole
J. D. Wagenveld, H. -R. Klöckner, N. Gupta +21
The number counts of homogeneous samples of radio sources are a tried and true method of probing the large scale structure of the Universe, as most radio sources outside the galact…
Discovery of Hydrogen Radio Recombination Lines at z=0.89 towards PKS 1830-211
Kimberly L. Emig, Neeraj Gupta, Pedro Salas +14
We report the detection of stimulated hydrogen radio recombination line (RRL) emission from ionized gas in a galaxy using 580--1670 MHz observations from the MeerKAT Absor…
PKS1413+135: OH and HI at z = 0.247 with MeerKAT
F. Combes, N. Gupta, S. Muller +13
The BL Lac PKS 1413+135 was observed by the Large Survey Project "MeerKAT Absorption Line Survey" (MALS) in the L-band, at 1139 MHz and 1293-1379 MHz, targeting the HI and OH lines…
