Astrophysical Journal, ISSN 0004-637X, 06/2015, Volume 805, Issue 2, pp. 124 - 8
Journal Article
ASTRONOMY & ASTROPHYSICS, ISSN 1432-0746, 08/2019, Volume 628, p. L6
While theoretical arguments predict that most of the early growth of supermassive black holes (SMBHs) happened during heavily obscured phases of accretion,...

Journal Article
Astronomy and Astrophysics, ISSN 0004-6361, 2012, Volume 537, p. L8
Most galaxy evolutionary models require quasar feedback to regulate star formation in their host galaxies. In particular, at high redshift, models expect that...
