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 =…
AGN Feedback in groups and clusters of galaxies
S. Raychaudhury, S. Giacintucci, E. O'Sullivan +5
The lack of very cool gas at the cores of groups and clusters of galaxies, even where the cooling time is significantly shorter than the Hubble time, has been interpreted as eviden…
A Joint GMRT/X-ray study of galaxy groups
E. O'Sullivan, S. Giacintucci, J. M. Vrtilek +4
We present results from combined low-frequency radio and X-ray studies of nearby galaxy groups. We consider two main areas: firstly, the evolutionary process from spiral-dominated,…
The GMRT Radio Halo Survey and low frequency follow-up
T. Venturi, S. Giacintucci, R. Cassano +6
The GMRT Radio Halo Survey, carried out at 610 MHz to investigate the statistical properties of cluster radio halos in a complete cluster sample selected in the redshift interval z…
A new approach to mitigation of radio frequency interference in interferometric data
Ramana Athreya
Radio frequency interference (RFI) is the principal factor limiting the sensitivities of radio telescopes, particularly at frequencies below 1 GHz. I present a conceptually new app…
