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…

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…
