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…
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…
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+}}…
