JWST/NIRSpec Reveals Diverse Nuclear Environments in Dwarf Galaxies Hosting AGN
Thomas Bohn, Archana Aravindan, Gabriela Canalizo +18
Dwarf galaxies, in the CDM framework, are expected to dominate the galaxy number density at all redshifts. As such, studying AGN in these systems, including characterizing their…
JWST Reveals a Candidate Supermassive Black Hole Binary at z=4.3 in the Brightest Sub-millimeter Galaxy in COSMOS-Web
Jed McKinney, Ansh Gupta, Julian B. Munoz +13
We present JWST/NIRSpec PRISM and G395M grating spectroscopy for AzTEC-1, a massive sub-mm bright galaxy at in the COSMOS extragalactic field. The PRISM spectrum reveals s…
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,…
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…
A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at
Tiger Yu-Yang Hsiao, John Chisholm, Danielle A. Berg +22
The competition between metal synthesis and feedback from massive stars establishes the mass-metallicity relation (MZR) at low-redshifts. Examining this relation at higher redshift…
GLIMPSED: Direct evidence for a fast active galactic nucleus-driven outflow from a z=6.64 little red dot host galaxy
Damien Korber, Rui Marques-Chaves, Daniel Schaerer +15
We report the discovery of GLIMPSED-329380, a z=6.64 galaxy behind Abell S1063, which shows signs of an extreme ionised outflow driven by an active galactic nucleus (AGN). The deep…
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…
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…
A High Resolution Search for Dual AGN Candidates in Mergers: A Pre-Selection Strategy using Keck AO
Camilo Vazquez, S. Satyapal, G. Canalizo +20
Accreting supermassive black holes (SMBHs) in galaxy mergers with separations 1 kpc are crucial to our understanding of SMBH growth, galaxy evolution, and SMBH binary evolution…
Selection of Dwarf Galaxies Hosting AGNs: A Measure of Bias and Contamination using Unsupervised Machine Learning Techniques
Sogol Sanjaripour, Archana Aravindan, Gabriela Canalizo +4
Identifying AGNs in dwarf galaxies is critical for understanding black hole formation but remains challenging due to their low luminosities, low metallicities, and star formation-d…
The JWST View of Cygnus A: Jet-Driven Coronal Outflow with a Twist
Patrick M. Ogle, B. Sebastian, A. Aravindan +29
We present first results from James Webb Space Telescope (JWST) Near-Infrared Spectrograph (NIRSpec), Mid-Infrared Instrument (MIRI), and Keck Cosmic Webb Imager (KCWI) integral fi…
A closer look at dwarf galaxies exhibiting MIR variability: AGN confirmation and comparison with non-variable dwarf galaxies
Archana Aravindan, Gabriela Canalizo, Nathan Secrest +2
Detecting active black holes in dwarf galaxies has proven to be a challenge due to their small size and weak electromagnetic signatures. Mid-infrared variability has emerged as a p…
Fast Outflows and Luminous He II Emission in Dwarf Galaxies with AGN
Weizhe Liu, Sylvain Veilleux, Gabriela Canalizo +6
While stellar processes are believed to be the main source of feedback in dwarf galaxies, the accumulating discoveries of AGN in dwarf galaxies over recent years arouse the interes…
A Comparison of Outflow Properties in AGN Dwarfs vs. Star Forming Dwarfs
Archana Aravindan, Weizhe Liu, Gabriela Canalizo +5
Feedback likely plays a crucial role in resolving discrepancies between observed and theoretical predictions of dwarf galaxy properties. Stellar feedback was once believed to be su…
Nuclear Activity in the Low Metallicity Dwarf Galaxy SDSS J0944-0038: A Glimpse into the Primordial Universe
Michael Reefe, Shobita Satyapal, Remington O. Sexton +11
Local low metallicity dwarf galaxies are relics of the early universe and hold clues into the origins of supermassive black holes (SMBHs). In recent work, coronal lines have been u…
