Extragalactic globular clusters with Euclid and other wide surveys
Ariane Lançon, S. Larsen, K. Voggel +14
Globular clusters play a role in many areas of astrophysics, ranging from stellar physics to cosmology. New ground-based optical surveys complemented by observations from space-bas…
Resolved nuclear kinematics link the formation and growth of nuclear star clusters with the evolution of their early and late-type hosts
Francesca Pinna, Nadine Neumayer, Anil Seth +7
We present parsec-scale kinematics of eleven nearby galactic nuclei, derived from adaptive-optics assisted integral-field spectroscopy at (near-infrared) CO band-head wavelengths.…
The Loudest Stellar Heartbeat: Characterizing the most extreme amplitude heartbeat star system
T. Jayasinghe, C. S. Kochanek, J. Strader +16
We characterize the extreme heartbeat star system MACHO 80.7443.1718 in the LMC using TESS photometry and spectroscopic observations from the Magellan Inamori Kyocera Echelle (MIKE…
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…
A Gaia-based catalog of candidate stripped nuclei and luminous globular clusters in the halo of Centaurus A
Karina T. Voggel, Anil C. Seth, David J. Sand +4
Tidally stripped galaxy nuclei and luminous globular clusters (GCs) are important tracers of the halos and assembly histories of nearby galaxies, but are difficult to reliably iden…
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…
