The rate of stellar tidal disruption flares from SDSS data
Sjoert van Velzen, Glennys R. Farrar
We report an observational estimate of the rate of stellar tidal disruption flares (TDFs), based on our (successful) search for these events in archival Sloan Digital Sky Survey (S…
Constraints on off-axis jets from stellar tidal disruption flares
Sjoert van Velzen, Dale A. Frail, Elmar Koerding +1
Many decades of observations of active galactic nuclei and X-ray binaries have shown that relativistic jets are ubiquitous when compact objects accrete. One could therefore anticip…
Radio galaxies of the local universe: all-sky catalog, luminosity functions, and clustering
Sjoert van Velzen, Heino Falcke, Pim Schellart +2
To understand the feedback of black holes on their environment or the acceleration of ultra-high energy cosmic rays in the present cosmic epoch, a systematic, all-sky inventory of…
