A stringent constraint on the fractional change of proton g-factor

Renzhi Su, Stephen J. Curran, Jeremy Darling +5

We report a constraint on the cosmological variation of the proton g-factor, $g_{p}$ . By comparing the measured redshifts between \mbox{H\,{\sc i}} 21 cm and OH 18 cm lines observed…

VLBI studies of FLASH H I 21-cm absorbers -- I

J. N. H. S. Aditya, Elaine M. Sadler, Raffaella Morganti +9

We have conducted VLBA 1.4 GHz (L-band) continuum observations towards twelve sources with HI 21-cm absorption detections at redshift $0.4 < z < 0.7$ in the pilot surveys of FLASH, an…
