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 …

A significant fraction of nearby galaxies show evidence of weak nuclear activity unrelated to
normal stellar processes. Recent high-resolution, multiwavelength observations indicate that …

We aim to constrain the evolution of active galactic nuclei (AGNs) as a function of
obscuration using an X-ray-selected sample of∼ 2000 AGNs from a multi-tiered survey …

Context. The efficiency of the different processes responsible for the evolution of interstellar
dust on the scale of a galaxy are, to date, very uncertain, spanning several orders of …

It is well accepted that unabsorbed as well as absorbed active galactic nuclei (AGNs) are
needed to explain the nature and shape of the Cosmic X-ray background (CXB), even if the …

We present an updated mid-infrared (MIR) versus X-ray correlation for the local active
galactic nuclei (AGN) population based on the high angular resolution 12 and 18μm …

We present new photometry of 16 local Seyferts including 6 Compton-thick sources in N-
band filters around 12-μm, obtained with the VISIR instrument on the 8-m Very Large …

Observations of H 2 O masers from circumnuclear disks in active galaxies for the
Megamaser Cosmology Project (MCP) allow accurate measurement of the mass of …

We investigate the relation between X-ray nuclear emission, optical emission line
luminosities and black hole masses for a sample of 47 Seyfert galaxies. The sample, which …

We use new central stellar velocity dispersions and nuclear X-ray and Hα luminosities for
the Palomar survey of nearby galaxies to investigate the distribution of nuclear bolometric …
