A fourth HI 21-cm absorption system in the sight-line of MG J0414+0534: a record for intervening absorbers
A. Tanna, S. J. Curran, M. T. Whiting +2
We report the detection of a strong HI 21-cm absorption system at z=0.5344, as well as a candidate system at z=0.3389, in the sight-line towards the z=2.64 quasar MG J0414+0534. Th…
Measuring space-time variation of the fundamental constants with redshifted submillimetre transitions of neutral carbon
S. J. Curran, A. Tanna, F. E. Koch +4
We compare the redshifts of neutral carbon and carbon monoxide in the redshifted sources in which the fine structure transition of neutral carbon, [CI], has been detected, in order…
On the absence of molecular absorption in high redshift millimetre-band searches
S. J. Curran, M. T. Whiting, F. Combes +6
We have undertaken a search for millimetre-wave band absorption (through the CO and HCO+ rotational transitions) in the host galaxies of reddened radio sources (z = 0.405-1.802). D…
New searches for HI 21-cm in damped Lyman-alpha absorption systems
S. J. Curran, P. Tzanavaris, J. K. Darling +4
We present the results of three separate searches for HI 21-cm absorption in a total of twelve damped Lyman-alpha absorption systems (DLAs) and sub-DLAs over the redshift range z =…
