Counting the Unseen II: Tidal Disruption Event Rates in Nearby Galaxies with REPTiDE

Christian H. Hannah, Nicholas C. Stone, Anil C. Seth +1

Tidal disruption events (TDEs) are a class of transients that occur when a star is destroyed by the tides of a massive black hole (MBH). Their rates encode valuable MBH demographic…

Megahertz peaked-spectrum sources in the Boötes field I - a route towards finding high-redshift AGN?

Rocco Coppejans, David Cseh, Wendy L. Williams +2

We present a 324.5MHz image of the NOAO Boötes field that was made using Very Large Array (VLA) P-band observations. The image has a resolution of 5.6x5.1arcsec, a radius of $2.05^…
