Investigating the ionization mechanisms powering the extreme emission lines in metal-poor galaxies
C. Daoutis, V. Lebouteiller, D. Schaerer +11
Extreme emission metal-poor galaxies (EEMPGs) are excellent local laboratories for understanding the extreme physical conditions and ionizing radiation fields in the early Universe…
Search for High-Ionization Nebular Emission (SHINE). I. A Systematically Selected [Ne V] Sample at z > 3 with JWST/NIRSpec PRISM
Shobita Satyapal, Sara Doan, Daniel Schaerer +8
We conduct the first systematic Search for High-Ionization Nebular Emission (SHINE) using [Ne V] in JWST/NIRSpec PRISM spectroscopy at . From more than 9,000 gala…
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,…
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+}}…
Local Analogs of Primordial Galaxies: In Search of Intermediate Mass Black Holes with JWST NIRSpec
Sara Doan, Shobita Satyapal, William Matzko +15
Local low metallicity galaxies with signatures of possible accretion activity are ideal laboratories in which to search for the lowest mass black holes and study their impact on th…
CLASS Survey Description: Coronal Line Needles in the SDSS Haystack
Michael Reefe, Remington O. Sexton, Sara M. Doan +3
Coronal lines are a powerful, yet poorly understood, tool to identify and characterize Active Galactic Nuclei (AGNs). There have been few large scale surveys of coronal lines in th…
CLASS: Coronal Line Activity Spectroscopic Survey
Michael Reefe, Shobita Satyapal, Remington O. Sexton +3
We conduct the first systematic survey of a comprehensive set of the twenty optical coronal lines in the spectra of nearly 1 million galaxies observed by the Sloan Digital Sky Surv…
