    Dust Reverberation Mapping in Distant Quasars from Optical and Mid-infrared Imaging Surveys

    The size of the dust torus in active galactic nuclei (AGNs) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV...

    Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations

    Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted)...

    Exploring the Mid-infrared SEDs of Six AGN Dusty Torus Models. I. Synthetic Spectra

    At distances from the active galaxy nucleus where the ambient temperature falls below ̃1500-1800 K, dust is able to survive. It is thus possible to have a large...

    Extragalactic Magnetism with SOFIA (SALSA Legacy Program): The Magnetic Fields in the Multiphase Interstellar Medium of the Antennae Galaxies

    Mergers are thought to be a fundamental channel for galaxy growth, perturbing the gas dynamics and the magnetic fields (B-fields) in the interstellar medium...

    The JCMT BISTRO Survey: Studying the Complex Magnetic Field of L43

    We present observations of polarized dust emission at 850 μm from the L43 molecular cloud, which sits in the Ophiuchus cloud complex. The data were taken using...
