Swift Observations of Gaia BH3.

SBARUFATTI B., FALOMO R. and TREVES A.

Abstract (from CDS):

We present UV and X-ray observations, obtained with the Swift Observatory, of Gaia BH3, a binary system containing a 33 M⊙ black hole discovered through Gaia astrometry. The system is well detected in all UV and optical filters (1700-6500 Å). We compare our results with the modeling of the noncollapsed component using synthetic stellar libraries, and a good agreement is found with our UV observations.
