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 …

Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it
can control the critical process of transforming galaxies from star forming to quiescent …

Over the next 5 yr, the Dark Energy Spectroscopic Instrument (DESI) will use 10
spectrographs with 5000 fibers on the 4 m Mayall Telescope at Kitt Peak National …

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 …

Studies of the geometry and energy content of the Universe, physics of cosmic expansion,
fundamental properties of standard model particles, and growth of structure remain the key …

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 …

We study the abundance of substructure in the matter density near galaxies using ALMA
Science Verification observations of the strong lensing system SDP. 81. We present a …

We present new measurements of the evolution of the X-ray luminosity functions (XLFs) of
unabsorbed and absorbed active galactic nuclei (AGNs) out to z∼ 5. We construct samples …

We describe the design and data analysis of the DEEP2 Galaxy Redshift Survey, the
densest and largest high-precision redshift survey of galaxies at z∼ 1 completed to date …

We present two large catalogs of active galactic nucleus (AGN) candidates identified across
30,093 deg 2 of extragalactic sky from the Wide-field Infrared Survey Explorer's AllWISE …
