JWST Reveals Compact Nuclear Starbursts Masquerading as AGNs in Metal-Poor Dwarfs: Where Are the Accreting Intermediate-Mass Black Holes?
William Matzko, Shobita Satyapal, Jeffrey D. Mckaig +19
We present JWST/NIRSpec spectroscopy of the low-mass, metal-poor galaxy SDSS~J160135.95+311353.7 (J1601), selected for its extreme mid-infrared colors and compact nuclear emission,…
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…
AGN versus Star-formation: A MUSE Analysis of NGC 1365
Kyla Mullaney, Kelly E. Whalen, Jenna Cann +3
Active galactic nuclei (AGN) and star formation feedback may heat and remove gas from galaxies in a process that quenches ongoing star formation and shapes the evolution of galaxie…
An Increase in the Prevalence of Ionized Outflows in Galaxies with Coronal Line Emission: Feedback in Action?
William Matzko, Shobita Satyapal, Michael Reefe +3
Coronal lines (CLs), which arise from collisionally excited forbidden transitions from highly ionized species, are a powerful diagnostic tool in uncovering active galactic nuclei (…
The CLASS Quasar Catalog: Coronal Line Activity in Type 1 SDSS Quasars
Sara Doan, Shobita Satyapal, Michael Reefe +7
We conduct the first systematic survey of a total of eleven optical coronal lines in the spectra of a large sample of low redshift (z < 0.8) Type 1 quasars observed by the Sloan Di…
Why are optical coronal lines faint in active galactic nuclei?
Jeffrey D. McKaig, Shobita Satyapal, Ari Laor +4
Forbidden collisionally excited optical atomic transitions from high ionization potential (IP54.8\,eV) ions, such as Ca, Ne, Fe$^{\mathrm{6+}}…
