    HALF OF THE MOST LUMINOUS QUASARS MAY BE OBSCURED: INVESTIGATING THE NATURE OF WISE-SELECTED HOT DUST-OBSCURED GALAXIES by Assef, R. J., Eisenhardt, P. R. M., Stern, D., Tsai, C.-W., Wu, J., Wylezalek, D., Blain, A. W., Bridge, C. R., Donoso, E., Griffith, R. L., Jarrett, T. H., Gonzales, Alexandria

    Published 2015
    “…Alternatively, Hot DOGs may not be the torus-obscured counterparts of the known optically selected, largely unobscured, hyper-luminous QSOs, and may represent a new component of the galaxy evolution paradigm. Finally, we discuss the environments of Hot DOGs and statistically show that these objects are in regions as dense as those of known high-redshift proto-clusters.…”

    Published 2012
    “…Our goal is to produce deep galaxy number counts and redshift distributions below the confusion limit at SPIRE wavelengths (∼20 mJy), which we then use to place strong constraints on the origins of the cosmic infrared background and on models of galaxy evolution. Methods. We individually extracted the bright SPIRE sources (>20 mJy) in the COSMOS field with a method using the positions, the flux densities, and the redshifts of the 24 μm sources as a prior, and derived the number counts and redshift distributions of the bright SPIRE sources. …”

    Published 2023-01-01
    “…Despite the importance of active galactic nuclei (AGNs) in galaxy evolution, accurate AGN identification is often challenging, as common AGN diagnostics can be confused by contributions from star formation and other effects (e.g., Baldwin–Phillips–Terlevich diagrams). …”

    NuSTAR Observations of Four Mid-IR–Selected Dual AGN Candidates in Galaxy Mergers by Ryan W. Pfeifle, Kimberly Weaver, Shobita Satyapal, Claudio Ricci, Nathan J. Secrest, Mario Gliozzi, Laura Blecha, Barry Rothberg

    Published 2023-01-01
    “…Mergers of galaxies are a ubiquitous phenomenon in the universe and represent a natural consequence of the “bottom-up” mass accumulation and galaxy evolution cosmological paradigm. It is generally accepted that the peak of active galactic nucleus (AGN) accretion activity occurs at nuclear separations of ≲10 kpc for major mergers. …”

    Published 2023-01-01
    “…Dual active galactic nuclei (AGNs), which are the manifestation of two actively accreting supermassive black holes (SMBHs) hosted by a pair of merging galaxies, are a unique laboratory for studying the physics of SMBH feeding and feedback during an indispensable stage of galaxy evolution. In this work, we present NOEMA CO(2–1) observations of seven kiloparsec-scale dual-AGN candidates drawn from a recent Chandra survey of low redshift, optically classified AGN pairs. …”
