    Jet-driven shocks and turbulence in radio-loud active galactic nuclei observed with JWST MIRI/MRS
    Jet─cloud interactions are a key manifestation of active galactic nucleus (AGN) feedback on nuclear scales, which is distinct from the large-scale radio-mode...

    Jet-induced molecular gas excitation and turbulence in the Teacup
    In order to investigate the impact of radio jets on the interstellar medium (ISM) of galaxies hosting active galactic nuclei (AGN), we present subarcsecond...

    Jets from Subparsec to Kiloparsec Scales: A Physical Connection
    The Chandra discovery of bright X-ray emission from kiloparsec-scale jets allows insight into the physical parameters of the jet flow at large scales. At the...

    Joint gas and stellar dynamical models of WLM: an isolated dwarf galaxy within a cored, prolate DM halo
    We present multitracer dynamical models of the low-mass (M * ∼ 10 7), isolated dwarf irregular galaxy WLM in order to simultaneously constrain the inner slope...

    JWST MIRI reveals the diversity of nuclear mid-infrared spectra of nearby type 2 quasars
    Type 2 quasars (QSO2s) are active galactic nuclei (AGN) seen through a significant amount of dust and gas that obscures the central supermassive black hole and...

    JWST reveals extended stellar disks for ALMA-bright dusty star-forming galaxies in the Spiderweb protocluster
    We present JWST/NIRCam imaging of dusty star-forming galaxies (DSFGs) detected by the Atacama Large Millimetre/submillimetre Array (ALMA) in the Spiderweb...

    JWST reveals the diversity of nuclear obscuring dust in nearby AGN: nuclear isolation of MIRI/MRS data cubes and continuum spectral fitting
    We investigate the capabilities of the mid-infrared instrument (MIRI) of JWST to advance our knowledge of active galactic nucleus (AGN) dust using the spectral...

    Keck HIRES Spectroscopy of Extragalactic H II Regions: C and O Abundances from Recombination Lines
    We present very deep spectrophotometry of 14 bright extragalactic H II regions belonging to spiral, irregular, and blue compact galaxies. The data for 13...
