We analyse a sample of 69 quasi-stellar objects (QSOs) which have been randomly selected in a complete sample of 104 QSOs (R ≤ 18,0.142 < z < 0.198,δ < 10°). 60 have been observed with the NTT/SUSI2 at La Silla, through two filters in the optical band (WB 655 and V 812), and the remaining nine are taken from archive data bases. The filter V 812 contains the redshifted H,β and forbidden [O III] emission lines, while WB 655 covers a spectral region devoid of emission lines, thus measuring the QSO…

In a popular scenario for the coevolution of massive black holes and galaxies, major mergers of gas-rich galaxies fuel vigorous star formation and obscured (type 2) quasar activity until energy
CORRELATION BETWEEN GALAXY MERGERS AND LUMINOUS ACTIVE GALACTIC NUCLEI
• Physics
• 2015
It is not yet clear what triggers the activity of active galactic nuclei (AGNs), but galaxy merging has been suspected to be one of the main mechanisms fuelling the activity. Using deep optical
Morphologies of z ∼ 0.7 AGN host galaxies in CANDELS: no trend of merger incidence with AGN luminosity
The processes that trigger active galactic nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger disturbances are
Detection of Far-Infrared Emission from Galaxies and Quasars in the Galactic Extinction Map by Stacking Analysis

We have performed stacking image analyses of galaxies over the Galactic extinction map constructed by Schlegel, Finkbeiner & Davis (1998). We select ~10^7 galaxies in total from the Sloan Digital Sky

Evidence for a Young Stellar Population in Nearby Type 1 Active Galaxies
• Physics
The Astrophysical Journal
• 2019
To understand the physical origin of the close connection between supermassive black holes and their host galaxies, it is vital to investigate star formation properties in active galaxies. Using a
Do we expect most AGN to live in discs
• Physics
• 2014
Recent observations have indicated that a large fraction of the low- to intermediate-luminosity AGN population lives in disc-dominated hosts, while the more luminous quasars live in bulge-dominated
