A Long Period Stellar-Mass Black Hole Binary in Centauri
Matthew Whitaker, Evan Kerr, Anil Seth +16
Modern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited. We pr…
A spectroscopic map of the Galactic centre: Integrated light and dynamical modelling
A. Feldmeier-Krause, T. I. Maindl, G. van de Ven +3
The centre of the Milky Way is occupied by a nuclear star cluster that contains the supermassive black hole Sgr A*. The cluster is embedded in the larger surrounding nuclear stella…
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…
The SAMI Galaxy Survey: Quenching of Star Formation in Clusters III. Ram-Pressure-Affected Galaxy Populations
OÄuzhan Ãakır, Matt S. Owers, Luca Cortese +15
Cluster environments influence galaxy evolution by curtailing star formation activity, notably through ram-pressure stripping (RPS). In this study, using spatially resolved spectro…
Distance measurements from the internal dynamics of globular clusters: Application to the Sombrero galaxy (M104)
Katja Fahrion, Michael A. Beasley, Anastasia Gvozdenko +7
Globular clusters (GCs) are dense star clusters found in all massive galaxies. Recent work has established that they follow a tight relation between their internal stellar velocity…
Bar ages derived for the first time in nearby galaxies: Insights on secular evolution from the TIMER sample
Camila de Sá-Freitas, Dimitri A. Gadotti, Francesca Fragkoudi +9
Once galaxies settle their discs and become self-gravitating, stellar bars can form, driving the subsequent evolution of their host galaxy. Determining the ages of bars can therefo…
