AT 2020nov: Evidence for Disk Reprocessing in a Rare Tidal Disruption Event
Nicholas Earl, K. Decker French, Enrico Ramirez-Ruiz +23
We present a detailed analysis of AT 2020nov, a tidal disruption event (TDE) in the center of its host galaxy, located at a redshift of . AT 2020nov exhibits unique feat…
Anomaly Detection and Approximate Similarity Searches of Transients in Real-time Data Streams
P. D. Aleo, A. W. Engel, G. Narayan +29
We present LAISS (Lightcurve Anomaly Identification and Similarity Search), an automated pipeline to detect anomalous astrophysical transients in real-time data streams. We deploy…
The black hole occupation fraction of local dwarf galaxies with AXIS
Elena Gallo, Edmund Hodges-Kluck, Tommaso Treu +7
The fraction of local dwarf galaxies that hosts massive black holes is arguably the cleanest diagnostic of the dominant seed formation mechanism of today's supermassive black holes…
Multiwavelength Scrutiny of X-ray Sources in Dwarf Galaxies: ULXs versus AGN
Erica Thygesen, Richard M. Plotkin, Roberto Soria +10
Owing to their quiet evolutionary histories, nearby dwarf galaxies (stellar masses ) have the potential to teach us about the mechanism(s) t…
Intermediate-mass black holes and the fundamental plane of black hole accretion
Kayhan Gültekin, Kristina Nyland, Nichole Gray +7
We present new 5 GHz VLA observations of a sample of 8 active intermediate-mass black holes with masses found in galaxies with stellar masses $…
Massive black hole formation in dense stellar environments: Enhanced X-ray detection rates in high velocity dispersion nuclear star clusters
Vivienne F. Baldassare, Nicholas C. Stone, Adi Foord +2
We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense st…
