Estimating Bolometric Luminosities of Type 1 Quasars with Self-organizing Maps

The Astrophysical Journal
We present a new method to calculate bolometric luminosities for unobscured, type 1 quasars with multiband photometric data. Bolometric luminosity is a fundamental property for understanding quasars, and it is commonly estimated from monochromatic ...

Quasars Can Signpost Supermassive Black Hole Binaries

The Astrophysical Journal
Supermassive black holes (SMBHs) are found in the centers of massive galaxies, and galaxy mergers should eventually lead to SMBH mergers. Quasar activity has long been associated with galaxy mergers, so here we investigate if supermassive black hole ...
