GOODS–Herschel: an infrared main sequence for star-forming galaxies

We present the deepest 100 to 500 μm far-infrared observations obtained with the Herschel Space Observatory as part of the GOODS-Herschel key program, and examine the infrared (IR) 3–500 μm spectral…

Defining the intrinsic AGN infrared spectral energy distribution and measuring its contribution to the infrared output of composite galaxies

ABSTRACT We use infrared spectroscopy and photometry to empirically define the intrinsic, thermal in-frared spectral energy distribution (i.e., 6-100µm SED) of typical active galactic nuclei…

Kiloparsec-scale outflows are prevalent among luminous AGN: outflows and feedback in the context of the overall AGN population

In this chapter we aim to address the question: how common are kilo-parsec scale ionised outflows in the host galaxies of powerful active galactic nuclei (AGN; i.e., quasars) and what are their…

Narrow-line region gas kinematics of 24 264 optically selected AGN: the radio connection

Using a sample of 24 264 optically selected active galactic nuclei (AGNs) from the SDSS DR7 data base, we characterize how the profile of the [O III] λ5007 emission line relates to bolometric…

THE HIDDEN “AGN MAIN SEQUENCE”: EVIDENCE FOR A UNIVERSAL BLACK HOLE ACCRETION TO STAR FORMATION RATE RATIO SINCE z ∼ 2 PRODUCING AN MBH–M* RELATION

Using X-ray stacking analyses we estimate the average amounts of supermassive black hole (SMBH) growth taking place in star-forming galaxies at z ∼ 1 and z ∼ 2 as a function of galaxy stellar mass…

A CORRELATION BETWEEN STAR FORMATION RATE AND AVERAGE BLACK HOLE ACCRETION IN STAR-FORMING GALAXIES

We present a measurement of the average supermassive black hole accretion rate (BHAR) as a function of the star formation rate (SFR) for galaxies in the redshift range 0.25 < z < 0.8. We study a…

Energetic galaxy-wide outflows in high-redshift ultraluminous infrared galaxies hosting AGN activity

We present integral field spectroscopy observations, covering the [O iii] λλ4959, 5007 emission-line doublet of eight high-redshift (z = 1.4–3.4) ultraluminous infrared galaxies (ULIRGs) that host…

DEEP SILICATE ABSORPTION FEATURES IN COMPTON-THICK ACTIVE GALACTIC NUCLEI PREDOMINANTLY ARISE DUE TO DUST IN THE HOST GALAXY

We explore the origin of mid-infrared (mid-IR) dust extinction in all 20 nearby (z < 0.05) bona fide Compton-thick (NH > 1.5 × 1024 cm−2) active galactic nuclei (AGNs) with hard energy (E > 10 keV)…

A UNIFIED EMPIRICAL MODEL FOR INFRARED GALAXY COUNTS BASED ON THE OBSERVED PHYSICAL EVOLUTION OF DISTANT GALAXIES

We reproduce the mid-infrared to radio galaxy counts with a new empirical model based on our current understanding of the evolution of main-sequence (MS) and starburst (SB) galaxies. We rely on a…

A remarkably flat relationship between the average star formation rate and AGN luminosity for distant X-ray AGN.

In this study, we investigate the relationship between the star formation rate (SFR) and AGN luminosity (LAGNLAGN) for ∼2000 X-ray detected AGN. The AGN span over three orders of magnitude in X-ray…
