  • Localized H I 21-cm absorption towards a double-lobed z=0.24 radio galaxy 
    Curran, S. J.; Whiting, M. T.; Webb, J. K.; ATHREYA, RAMANA (Oxford University Press, 2011-06)
    We present the results of a mini-survey for associated HI 21-cm absorption at z≤ 0.42 with the Giant Metrewave Radio Telescope. Our targets are radio galaxies, selected on the basis that the γ ≈ 1216 Å luminosities are ...
  • A survey for H I in the distant Universe: the detection of associated 21-cm absorption at z = 1.28 
    Curran, S. J.; Whiting, M. T.; Tanna, A.; Sadler, E. M.; Pracy, M. B.; ATHREYA, RAMANA (Oxford University Pres, 2013-03)
    We have undertaken a survey for H I 21-cm absorption within the host galaxies of z ∼ 1.2-1.5 radio sources, in the search of the cool neutral gas currently ‘missing’ at z ≳ 1. This deficit is believed to be due to the ...
  • A search for H I and OH absorption in z ≳ 3 CO emitters 
    Curran, S. J.; Allison, J. R.; Whiting, M. T.; Sadler, E. M.; Combes, F.; Pracy, M. B.; Bignell, C.; ATHREYA, RAMANA (Oxford University Press, 2016-02)
    We present the results of a survey for H I 21 cm and OH 18 cm absorption in seven strong CO emitters at z ≳ 3. Despite reaching limits comparable to those required to detect 21 cm absorption at lower redshifts, we do not ...
  • Atomic and molecular absorption in redshifted radio sources 
    Curran, S. J.; Whiting, M. T.; Allison, J. R.; Tanna, A.; Sadler, E. M.; ATHREYA, RAMANA (Oxford University Press, 2017-06)
    We report on a survey for associated H I 21-cm and OH 18-cm absorption with the Giant Metrewave Radio Telescope at redshifts z ≈ 0.2–0.4. Although the low-redshift selection ensures that our targets are below the critical ...
