Unveiling the origin of the optical/UV emission from the Galactic ULX Swift J0243.6+6124 during its 2017-2018 giant outburst

J. Alfonso-Garzón, J. van den Eijnden, N. P. M. Kuin +8

From late September 2017 to February 2018, the Be X-ray binary (BeXB) Swift J0243.6+6124 underwent an unprecedently bright giant outburst. The reported X-ray luminosities were so h…

Reliable Identification of Binary Supermassive Black Holes from Rubin Observatory Time-Domain Monitoring

Megan C. Davis, Kaylee E. Grace, Jonathan R. Trump +7

Periodic signatures in time-domain observations of quasars have been used to search for binary supermassive black holes. These searches, across existing time-domain surveys, have p…

Detection of X-ray/UV delay in NGC 4051 using AstroSat observations

Kavita Kumari, G. C. Dewangan, I. E. Papadakis +1

We study the connection between the variations in the far ultra-violet (FUV), near ultra-violet (NUV) and X-ray band emission from NGC 4051 using 4-days long AstroSat observations…
