Multiple H I 21-cm absorbers towards blazar PKS 1158+007
Abhisek Mohapatra, R. Srianand, R. Dutta
We report an interesting line of sight towards the blazar PKS 1158+007 (J1201+0028) ( = 1.369), revealing the rare detection of two intervening HI 21-cm absorption syst…
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
