Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

We summarize what large surveys of the contemporary Universe have taught us about the
physics and phenomenology of the processes that link the formation and evolution of …

The study of galaxy evolution hinges on our ability to interpret multiwavelength galaxy
observations in terms of their physical properties. To do this, we rely on spectral energy …

Source classifications, stellar masses, and star-formation rates are presented for≈ 80 000
radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey …

Far-infrared and submillimeter wavelength surveys have now established the important role
of dusty, star-forming galaxies (DSFGs) in the assembly of stellar mass and the evolution of …

ABSTRACT The Wide-field Infrared Survey Explorer (WISE) is an extremely capable and
efficient black hole finder. We present a simple mid-infrared color criterion, W1− W2⩾ 0.8 …

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 …

Spitzer/IRAC selection is a powerful tool for identifying luminous active galactic nuclei
(AGNs). For deep IRAC data, however, the AGN selection wedges currently in use are …

We have carried out a survey of the north and south ecliptic poles, EP-N and EP-S,
respectively, with the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer …

ABSTRACT A two-parameter semi-empirical model is presented for the spectral energy
distributions of galaxies with contributions to their infrared–submillimeter–radio emission …
