Abstract

We present a multi-frequency study of the intermediate spiral SAB(r)bc type galaxy NGC 6744, using available data from the Chandra X-Ray telescope, radio continuum data from the Australia Telescope Compact Array and Murchison Widefield Array, and Wide-field Infrared Survey Explorer infrared observations. We identify 117 X-ray sources and 280 radio sources. Of these, we find nine sources in common between the X-ray and radio catalogues, one of which is a faint central black hole with a bolometric radio luminosity similar to the MilkyWay's central black hole.We classify 5 objects as supernova remnant (SNR) candidates, 2 objects as likely SNRs, 17 as H II regions, 1 source as an AGN; the remaining 255 radio sources are categorised as background objects and one X-ray source is classified as a foreground star.We find the star-formation rate (SFR) of NGC 6744 to be in the range 2.8-4.7 M⊙ yr-1. signifying the galaxy is still actively forming stars. The specific SFR of NGC 6744 is greater than that of late-type spirals such as the MilkyWay, but considerably less that that of a typical starburst galaxy.
