Testing the binary hypothesis: pulsar timing constraints on supermassive black hole binary candidates by Sesana, A, Haiman, Z, Kocsis, B, Kelley, LZ

“…The inspection of $\approx$250k quasars in CRTS resulted in a catalogue of 111 potentially periodic sources, put forward as supermassive black hole binary (SMBHB) candidates. A similar investigation on PTF data yielded 33 candidates from a sample of $\approx$35k quasars. …”

Probing the Subparsec Dust of a Supermassive Black Hole with the Tidal Disruption Event AT 2020mot by Megan Newsome, Iair Arcavi, D. Andrew Howell, Jamison Burke, Kishalay De, Yael Dgany, Sara Faris, Joseph Farah, Daichi Hiramatsu, Curtis McCully, Estefania Padilla-Gonzalez, Craig Pellegrino, Giacomo Terreran

“…We model our observations following van Velzen et al. and find that the near-infrared light curve can be explained by concentric rings of thin dust within ∼0.1 pc of a ∼6 × 10 ^6 M _⊙ supermassive black hole (SMBH), among the smallest scales at which dust has been inferred near SMBHs. …”

Slowly Rotating Accretion Flow Around Supermassive Black Holes in Elliptical Galaxies: Case With Outflow by Razieh Ranjbar, Shahram Abbassi

“…One of the primary aims of this study is to investigate the solutions of slowly rotating accretion flows around supermassive black holes with outflows. This paper presents two distinct physical regions, supersonic and subsonic, which extend from the outer boundary to the black hole. …”

“…The Event Horizon Telescope (EHT) is a project to assemble a Very Long Baseline Interferometry (VLBI) network of millimeter wavelength dishes that can resolve strong field general relativistic signatures near a supermassive black hole. As planned, the EHT will include enough dishes to enable imaging of the predicted black hole "shadow," a feature caused by severe light bending at the black hole boundary. …”
