Clumpy Disk, Interloper, or Merger? Nature of a Distant Galaxy Pair at 5 kpc Projected Separation

Hajar Aziz, Vivian U, Archana Aravindan +8

We present the morphological, photometric, and spectroscopic properties of a z ~ 1 galaxy, "lil gal", serendipitously detected in JWST Mid Infrared Instrument (MIRI) images of near…

Probing Heavily Obscured AGN in Major Galaxy Mergers Using the mm-X-ray Correlation

M. Droguett-Callejas, E. Treister, L. Barcos-Muñoz +10

The study of heavily obscured supermassive black hole (SMBH) growth in late-stage galaxy mergers is challenging: column densities can bloc…

Probing AGN Feedback in Dwarf Galaxies with Spatially Resolved NIR Coronal Lines from JWST

Archana Aravindan, Thomas Bohn, Gabriela Canalizo +20

We present the first spatially resolved investigation of near-infrared coronal lines in dwarf galaxies hosting active galactic nuclei (AGN), using JWST/NIRSpec integral field spect…

Constraining Nuclear Molecular Gas Content with High-resolution CO Imaging of GOALS Galaxies

James Agostino, Anne M. Medling, Loreto Barcos-Muñoz +11

We present measurements of the cool molecular gas mass around the nuclei of two gas-rich mergers, III Zw 035 and IRAS F01364-1042, whose enclosed masses (M) within t…

A precessing jet from an active galactic nucleus drives gas outflow from a disk galaxy

Justin A. Kader, Vivian U, Loreto Barcos-Muñoz +30

To reproduce observed galaxy properties, cosmological simulations require that massive galaxies experience feedback from active galactic nuclei, which regulates star formation with…

The molecular diversity of the ISM in galaxies across cosmic time

Mathilde Bouvier, Yiqing Song, Michael Romano +7

Submillimetre molecular lines (e.g., CO, HCN, SiO) provide a uniquely powerful view of the physical and chemical processes that govern star formation (SF) and galaxy evolution. Yet…
