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…

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…

JWST lensed quasar dark matter survey I: Description and First Results

A. M. Nierenberg, R. E. Keeley, D. Sluse +18

The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespect…

NuSTAR Observations of Candidate Subparsec Binary Supermassive Black Holes

M. Lynne Saade, Murray Brightman, Daniel Stern +12

We present analysis of NuSTAR X-ray observations of three AGN that were identified as candidate subparsec binary supermassive black hole (SMBH) systems in the Catalina Real-Time Tr…

A Highly Magnified Gravitationally Lensed Red QSO at z = 2.5 with a Significant Flux Ratio Anomaly

Eilat Glikman, Cristian E. Rusu, Geoff C. -F. Chen +12

We present the discovery of a gravitationally lensed dust-reddened QSO at z = 2.517, identified in a survey for QSOs by infrared selection. Hubble Space Telescope imaging reveals a…
