Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

We review results from cosmic X-ray surveys of active galactic nuclei (AGNs) over the past
≈ 15≈ 15 years that have dramatically improved our understanding of growing …

We use the first systematic data sets of CO molecular line emission in z∼ 1–3 normal star-
forming galaxies (SFGs) for a comparison of the dependence of galaxy-averaged star …

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 …

We report the results from a systematic search for molecular (OH 119 μm) outflows with
Herschel/PACS in a sample of 43 nearby (z< 0.3) galaxy mergers, mostly ultraluminous …

We investigate the effect of active galactic nucleus (AGN) variability on the observed
connection between star formation and black hole accretion in extragalactic surveys. Recent …

" Research into active galactic nuclei (AGN)-the compact, luminous hearts of many galaxies-
is at the forefront of modern astrophysics. Understanding these objects requires extensive …

We study the dust content of galaxies from z= 0 to z= 9 in semi-analytic models of galaxy
formation that include new recipes to track the production and destruction of dust. We …

New surface photometry of all known elliptical galaxies in the Virgo cluster is combined with
published data to derive composite profiles of brightness, ellipticity, position angle, isophote …

Clumpy torus models with\mathstrut {\cal N} _ {0}\sim 5 {\mbox {--}} 15 dusty clouds along
radial equatorial rays successfully explain AGN infrared observations. The dust has …
