TL;DR
The MAVERIC survey conducted deep radio observations of 26 southern globular clusters, cataloging 1285 sources, revealing populations of compact objects and new binary candidates, thus providing insights into cluster demographics.
Contribution
This study provides the first comprehensive radio source catalog for 26 globular clusters, identifying potential new compact binaries and advancing understanding of cluster populations.
Findings
Detected 1285 radio sources across 26 clusters
Identified significant populations in 7 clusters
Discovered a candidate ultracompact black hole binary
Abstract
Radio continuum observations offer a new window on compact objects in globular clusters compared to typical X-ray or optical studies. As part of the MAVERIC survey, we have used the Australia Telescope Compact Array to carry out a deep (median central noise level of approximately 4 microJy per beam) radio continuum survey of 26 southern globular clusters at central frequencies of 5.5 and 9.0 GHz. This paper presents a catalogue of 1285 radio continuum sources in the fields of these 26 clusters. Considering the surface density of background sources, we find significant evidence for a population of radio sources in seven of the 26 clusters, and also identify at least 11 previously known compact objects (6 pulsars and 5 X-ray binaries). While the overall density of radio continuum sources with 7.25-GHz flux densities greater than about 20 microJy in typical globular clusters is relatively…
