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,…
Jet-driven shocks and turbulence in radio-loud Active Galactic Nuclei observed with JWST MIRI/MRS
Rogemar A. Riffel, Gabriel L. Souza-Oliveira, Luis Colina +34
Jet-cloud interactions are a key manifestation of Active Galactic Nucleus (AGN) feedback on nuclear scales, distinct from the large-scale radio-mode feedback that suppresses gas co…
Revisiting the Claim for a Direct-Collapse Black Hole in UHZ1 at
Fan Zou, Elena Gallo, Zihao Zuo +8
We reassess the direct collapse black hole (DCBH) interpretation of UHZ1 (UNCOVER-26185), a gravitationally lensed galaxy at . That interpretation rests on…
ReveaLLAGN 1: JWST Emission-Line Spectra Reveal Low-Luminosity AGN with UV-Deficient SEDs and Warm Molecular Gas
Kameron Goold, Anil Seth, Mallory Molina +20
We present near- and mid-infrared spectra of eight Low-Luminosity Active Galactic Nuclei (LLAGN), spanning nearly four orders of magnitude in black hole mass and Eddington ratio, o…
Central Massive Black Holes Are Not Ubiquitous in Local Low-Mass Galaxies
Fan Zou, Elena Gallo, Anil C. Seth +13
The black-hole occupation fraction () defines the fraction of galaxies that harbor central massive black holes (MBHs), irrespective of their accretion activity leve…
WIggle Corrector Kit for NIRSpEc Data: WICKED
Antoine Dumont, Nadine Neumayer, Anil C. Seth +8
The point-spread function of the integral-field unit (IFU) mode of the JWST's NIRSpec is heavily under-sampled, creating resampling noise seen as low-frequency sinusoidal-like arti…
Counting the Unseen II: Tidal Disruption Event Rates in Nearby Galaxies with REPTiDE
Christian H. Hannah, Nicholas C. Stone, Anil C. Seth +1
Tidal disruption events (TDEs) are a class of transients that occur when a star is destroyed by the tides of a massive black hole (MBH). Their rates encode valuable MBH demographic…
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…
Counting the Unseen I: Nuclear Density Scaling Relations for Nucleated Galaxies
Christian H. Hannah, Anil C. Seth, Nicholas C. Stone +1
The volumetric rate of tidal disruption events (TDEs) encodes information on the still-unknown demographics of central massive black holes (MBHs) in low-mass galaxies ($\lesssim 10…
Hubble Space Telescope Imaging of the Ultra-Compact High Velocity Cloud AGC 226067: A stripped remnant in the Virgo Cluster
D. J. Sand, A. C. Seth, D. Crnojević +10
We analyze the optical counterpart to the ultra-compact high velocity cloud AGC 226067, utilizing imaging taken with the Advanced Camera for Surveys (ACS) on the Hubble Space Teles…
