Radio/X-ray sources of 35 CHANG-ES galaxies
Listed in IVOA Registry (Virtual Observatory)
We present catalogues of discrete, compact radio sources in and around the discs of 35 edge-on galaxies in the Continuum Halos in Nearby Galaxies - an EVLA Survey.
Description
The sources were extracted using the pybdsf program at both 1.6 GHz (L band) and 6.0 GHz (C band) from matching resolution (~=3 arcsec) data. We also present catalogues of X-ray sources from Chandra data sets for 27 of the galaxies.
The sources at the two radio frequency bands were positionally cross- correlated with each other, and the result cross-correlated with the X-ray sources. All catalogues are included for download with this paper. We detect a total of 2507 sources at L band and 1413 sources at C band. 75 sources have been successfully cross-correlated in both radio bands plus X-ray.

Three new nuclear sources are candidates for low luminosity active galactic nuclei in NGC 3877, NGC 4192, and NGC 5792; the one in NGC 3877 also appears to be variable. We also find new nuclear sources in two companion galaxies: NGC 4435 (companion to NGC 4438) and NGC 4298 (companion to NGC 4302). We have also discovered what appears to be a foreground double star; each star has X-ray emission and there is radio emission at both L band and C band in between them.
This could be a colliding wind binary system. Suggestions for follow-up studies are offered.
