The nature of ASASSN-24fw's occultation: modelling the event as dimming by optically thick rings around a sub-stellar companion
Sarang Shah, Jonathan P. Marshall, Carlos del Burgo +12
ASASSN-24fw is a main-sequence F-type star that experienced a rapid and long-lasting dimming event beginning in late 2024 and continuing until mid 2025. Its pre-dimming spectral en…
An Extremely Luminous Flare Recorded from a Supermassive Black Hole
Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17
Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…
Identifying tidal disruption events among radio transient galaxies
M. Kunert-Bajraszewska, D. KozieÅ-Wierzbowska, D. Stern +4
We present the optical and infrared properties of a sample of 24 radio transient sources discovered in the Very Large Array Sky Survey (VLASS). Previous studies of their radio emis…
Infrared-Selected Active Galactic Nuclei in the Kepler Fields
Tran Tsan, Matthew Malkan, Rick Edelson +3
We utilized the Edelson and Malkan (2012) and Stern et al. (2012) selection techniques and other methods to identify AGN candidates that were monitored during the Kepler prime and…
Searching for electromagnetic emission in an AGN from the gravitational wave binary black hole merger candidate S230922g
Tomás Cabrera, Antonella Palmese, Lei Hu +17
We carried out long-term monitoring of the LIGO/Virgo/KAGRA binary black hole (BBH) merger candidate S230922g in search of electromagnetic emission from the interaction of the merg…
