The Delay Time Distribution of Tidal Disruption Events
Margaret Shepherd, K. Decker French, Nicholas C. Stone +6
Tidal disruption events (TDEs) can be observed when stars get too close to supermassive black holes and are torn apart and accreted. The delay time distribution of TDEs, or rate of…
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…
XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy
Peter G. Boorman, Jiří Svoboda, Daniel Stern +23
Green Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local universe. They are believed to be analogues of high-redshift gala…
The origin of the nano-Hertz stochastic gravitational wave background: the contribution from supermassive black-hole binaries
Jean J. Somalwar, Vikram Ravi
The nano-Hertz gravitational wave background (GWB) is a key probe of supermassive black hole (SMBH) formation and evolution, if the background arises predominantly from binary SMBH…
Hyper Suprime-Cam Low Surface Brightness Galaxies II: A Hubble Space Telescope Study of the Globular Cluster Systems of Ultra-Diffuse Galaxies in Groups
Jean J. Somalwar, Jenny E. Greene, Johnny P. Greco +4
We increase the sample of ultra diffuse galaxies (UDGs) in lower density environments with characterized globular cluster (GC) populations using new Hubble Space Telescope observat…
Spatially-resolved UV diagnostics of AGN feedback: radiation pressure dominates in a prototypical quasar-driven superwind
Jean Somalwar, Sean D. Johnson, Jonathan Stern +5
Galactic-scale winds driven by active galactic nuclei (AGN) are often invoked to suppress star formation in galaxy evolution models, but the mechanisms driving these outflows are h…
