A new sample of Little Red Dots at in DESI DR1: Broad Balmer lines, low ionization spectrum and no variability
Kevin Park, Alberto Torralba, Jorryt Matthee +4
JWST has unveiled an abundant population of compact broad-line emitters largely at , the Little Red Dots (LRDs), which might represent a previously unprobed supermassive…
Plato's view on supermassive black hole binaries: Exploring the faint limit of ESA's Plato space mission
Nicholas Jannsen, Pablo Huijse, Kevin Park +3
The search for supermassive black hole binaries (SMBHBs) has, in recent years, seen the dawn of exploration with several hundred candidates claimed from photometric and spectroscop…
Self-lensing flares from black hole binaries V: systematic searches in LSST
Kevin Park, Zoltan Haiman, Chengcheng Xin +3
The Vera C. Rubin Observatory has now seen first light, and over a 10 year duration, LSST is projected to catalogue tens of millions of quasars, many of which are expected to be as…
Self-lensing flares from black hole binaries IV: the number of detectable shadows
Kevin Park, Chengcheng Xin, Jordy Davelaar +1
Sub-parsec supermassive black hole (SMBH) binaries are expected to be common in active galactic nuclei (AGN), as a result of the hierarchical build-up of galaxies via mergers. Whil…
