Imaging results from the legacy GMRT Galaxy Cluster Key Project
Lijo T. George, Ruta Kale, Yogesh Wadadekar
We have used archival GMRT data to image and study 39 galaxy clusters. These observations were made as part of the GMRT Key Project on galaxy clusters between 2001 and 2004. The ob…
An upper limit calculator (UL-CALC) for undetected extended sources with radio interferometers: radio halo upper limits
Lijo T. George, Ruta Kale, Yogesh Wadadekar
Radio halos are diffuse, extended sources of radio emission detected primarily in massive, merging galaxy clusters. In smaller and/or relaxed clusters, where no halos are detected,…
Data-Efficient Classification of Radio Galaxies
Ashwin Samudre, Lijo George, Mahak Bansal +1
The continuum emission from radio galaxies can be generally classified into different morphological classes such as FRI, FRII, Bent, or Compact. In this paper, we explore the task…
GMRT Archive Processing Project
Shubhankar Deshpande, Yogesh Wadadekar, Huib Intema +7
The GMRT Online Archive now houses over 120 terabytes of interferometric observations obtained with the GMRT since the observatory began operating as a facility in 2002. The utilit…
Twin radio relics in a near-by low-mass galaxy cluster Abell 168
K. S. Dwarakanath, Viral Parekh, Ruta Kale +1
We report the discovery of twin radio relics in the outskirts of the low-mass merging galaxy cluster Abell 168 (redshift=0.045). One of the relics is elongated with a linear extent…
A study of halo and relic radio emission in merging clusters using the Murchison Widefield Array
L. T. George, K. S. Dwarakanath, M. Johnston-Hollitt +18
We have studied radio haloes and relics in nine merging galaxy clusters using the Murchison Widefield Array (MWA). The images used for this study were obtained from the GaLactic an…
