Chandra observations of Galaxy Zoo mergers : Frequency of binary active nuclei in massive mergers
(2012-07-10)
We present the results from a Chandra pilot study of 12 massive galaxy mergers selected from Galaxy Zoo. The sample includes major mergers down to a host galaxy mass of 1011 M ☉ that already have optical active galactic ...
Probing quasar shutdown timescales with Hanny's Voorwerp
(American Institute of Physics (AIP), 2012)
Galaxy formation is significantly modulated by energy output from supermassive black holes at the centers of galaxies which grow in highly efficient luminous quasar phases. The timescale on which black holes transition ...
