SDSS-V Local Volume Mapper (LVM): The Integrated Light and Internal Rotation of Omega Centauri
Maximilian Häberle, Dmitry Bizyaev, Alina Boecker +34
The SDSS-V Local Volume Mapper (LVM) is a wide-field integral field spectroscopic survey of the Southern Milky Way plane, the Magellanic Clouds, and nearby Local Group galaxies. We…
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…
Shedding the envelope: JWST reveals a kiloparsec-scale [OIII]-weak Balmer shell around a z=7.64 quasar
Julien Wolf, Eduardo Bañados, Xiaohui Fan +25
Luminous quasars at the redshift frontier z>7 serve as stringent probes of super-massive black hole formation and they are thought to undergo much of their growth obscured by dense…
X-ray Constraints on Wandering Black Holes in Stripped Galaxy Nuclei in the Halo of NGC 5128
S. L. Feyan, R. Urquhart, J. Strader +6
A subset of galaxies have dense nuclei, and when these galaxies are accreted and tidally stripped, the nuclei can masquerade as globular clusters in the halos of large galaxies. If…
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…
Fast-moving stars around an intermediate-mass black hole in Omega Centauri
Maximilian Häberle, Nadine Neumayer, Anil Seth +15
Black holes have been found over a wide range of masses, from stellar remnants with masses of 5-150 solar masses (Msun), to those found at the centers of galaxies with Msu…
ReveaLLAGN 0: First Look at JWST MIRI data of Sombrero and NGC 1052
K. Goold, A. Seth, M. Molina +28
We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGN. We focus on two observations with th…
Investigating the Dark Matter Halo of NGC 5128 using a Discrete Dynamical Model
Antoine Dumont, Anil C. Seth, Jay Strader +7
As the nearest accessible massive early-type galaxy, NGC 5128 presents an exceptional opportunity to measure dark matter halo parameters for a representative elliptical galaxy. Her…
New Velocity Measurements of NGC 5128 Globular Clusters out to 130 kpc: Outer Halo Kinematics, Substructure and Dynamics
A. K. Hughes, D. J. Sand, A. Seth +11
We present new radial velocity measurements from the Magellan and the Anglo-Australian Telescopes for 174 previously known and 122 newly confirmed globular clusters (GCs) around NG…
A population of luminous globular clusters and stripped nuclei with elevated mass to light ratios around NGC 5128
Antoine Dumont, Anil C. Seth, Jay Strader +8
The dense central regions of tidally disrupted galaxies can survive as ultra-compact dwarfs (UCDs) that hide among the luminous globular clusters (GCs) in the halo of massive galax…
First direct dynamical detection of a dual supermassive black hole system at sub-kiloparsec separation
Karina. T. Voggel, Anil C. Seth, Holger Baumgardt +7
We investigated whether the two recently discovered nuclei in NGC7727 both host a super-massive black hole (SMBH). We used the high spatial resolution mode of the integral-field sp…
Spatially Resolving the Star Formation Histories of Three Nearby Nuclear Star Clusters
Christian H. Hannah, Anil C. Seth, Dieu D. Nguyen +4
The formation of nuclear star clusters (NSCs) remains an open question. In this work, we use spatially resolved HST/STIS spectroscopic observations of three nearby NSCs (hosted by…
NGC 5128 globular cluster candidates out to 150 kpc: a comprehensive catalog from Gaia and ground based data
Allison K. Hughes, David J. Sand, Anil Seth +9
We present a new catalog of 40502 globular cluster (GC) candidates in NGC 5128 out to a projected radius of 150 kpc, based on data from the Panoramic Imaging Survey of Centau…
Surprisingly Strong K-band Emission Found in Low Luminosity Active Galactic Nuclei
Antoine Dumont, Anil Seth, Jay Strader +3
We examine the near-infrared (NIR) emission from low-luminosity AGNs (LLAGNs). Our galaxy sample includes 15 objects with detected 2-10 keV X-ray emission, dynamical black hole mas…
Improved Dynamical Constraints on the Masses of the Central Black Holes in Nearby Low-mass Early-type Galactic Nuclei And the First Black Hole Determination for NGC 205
Dieu D. Nguyen, Anil C. Seth, Nadine Neumayer +17
We improve the dynamical black hole (BH) mass estimates in three nearby low-mass early-type galaxies--NGC 205, NGC 5102, and NGC 5206. We use new \hst/STIS spectroscopy to fit the…
