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…
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…
