Ultraviolet survey of M31 with UVIT on AstroSat

DOI

An ultraviolet survey of M31 has been carried out during 2017-19 with the UltraViolet Imaging Telescope (UVIT) instrument on board the AstroSat Observatory. Here we analyze far- and near-ultraviolet (FUV and NUV) observations from the M31 UVIT survey, which covers a sky area of ~3{deg}x1{deg} with spatial resolution of ~1". The observations included six filter bands in the wavelength range of 120-280nm. The limiting magnitude (AB) in the FUV band (CaF2 filter), which has the largest number of detected sources, is ~23. The primary product of this work is the M31 UVIT point-source catalog containing positions and photometry. In total ~75000 sources were detected at FUV or NUV wavelengths.
