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…
oMEGACat. X. Shedding light on the disrupted dwarf galaxy of Omega Centauri
Stefano Souza, Nadine Neumayer, Anil C. Seth +15
Omega Centauri (Cen) is the most massive and chemically complex star cluster in the Milky Way and is widely regarded as the surviving nuclear star cluster of an accreted dwarf…
oMEGACat. IX. Chemical Tagging of Omega Centauri Populations with Machine-Learning-Inferred Abundances from the MUSE Spectrograph
Z. Wang, A. C. Seth, C. Clontz +14
We present chemical abundance measurements for 7,302 red giant branch stars within the half-light radius (~5') of Centauri ( Cen), derived from MUSE spectra using the neural…
oMEGACat. VIII. A Subpopulation Census of ω Centauri
C. Clontz, A. C. Seth, Z. Wang +8
An understanding of the assembly history of the complex star cluster Omega Centauri has long been sought after, with many studies separating the stars on the color-magnitude diagra…
oMEGACat. VII. Tracing Interstellar and Intracluster Medium of Centauri using Sodium Absorptions
Z. Wang, A. C. Seth, M. Latour +14
We investigate the foreground interstellar medium along the line of sight and intracluster medium of Centauri ( Cen) by measuring the equivalent width of Na I D absorptions…
oMEGACat. VI. Analysis of the overall kinematics of Omega Centauri in 3D: velocity dispersion, kinematic distance, anisotropy, and energy equipartition
Maximilian Häberle, Nadine Neumayer, Callie Clontz +15
Omega Centauri ( Cen) is the Milky Way's most massive globular cluster and is likely the stripped nucleus of an accreted dwarf galaxy. In this paper, we analyze Cen's kinema…
Studying Binary Systems in Omega Centauri with MUSE: II. Observational constraints on the orbital period distribution
S. Saracino, S. Kamann, F. Wragg +8
Omega Centauri ( Cen) is one of the most complex star clusters in the Milky Way, and likely the stripped nucleus of an accreted dwarf galaxy. Being the subject of debate between…
oMEGACat V: Helium Enrichment in Centauri as a Function of Metallicity
C. Clontz, A. C. Seth, Z. Wang +12
Constraining the helium enhancement in stars is critical for understanding the formation mechanisms of multiple populations in star clusters. However, measuring helium variations f…
oMEGACat IV: Constraining Ages of Omega Centauri sub-giant branch stars with HST and MUSE
C. Clontz, A. C. Seth, A. Dotter +13
We present age estimates for over 8100 sub-giant branch (SGB) stars in Omega Centauri ( Cen) to study its star formation history. Our large data set, which combines multi-wavele…
oMEGACat III. Multi-band photometry and metallicities reveal spatially well-mixed populations within Centauri's half-light radius
M. S. Nitschai, N. Neumayer, M. Häberle +15
Centauri, the most massive globular cluster in the Milky Way, has long been suspected to be the stripped nucleus of a dwarf galaxy that fell into the Galaxy a long time ago. Th…
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…
oMEGACat II -- Photometry and proper motions for 1.4 million stars in Omega Centauri and its rotation in the plane of the sky
Maximilian Häberle, Nadine Neumayer, Andrea Bellini +15
Omega Centauri ( Cen) is the most massive globular cluster of the Milky Way. It is thought to be the nucleus of an accreted dwarf galaxy because of its high mass and its complex…
Centauri: A MUSE discovery of a counter-rotating core
Renuka Pechetti, Sebastian Kamann, Davor Krajnovic +7
Centauri is considered the most massive globular cluster of the Milky Way and likely the former nuclear star cluster of a galaxy accreted by the Milky Way. It is speculated to…
PHANGS-JWST: Data Processing Pipeline and First Full Public Data Release
Thomas G. Williams, Janice C. Lee, Kirsten L. Larson +55
The exquisite angular resolution and sensitivity of JWST is opening a new window for our understanding of the Universe. In nearby galaxies, JWST observations are revolutionizing ou…
Expanding on the Fundamental Metallicity Relation in Dwarf Galaxies with MUSE
Teodora-Elena Bulichi, Katja Fahrion, François Mernier +10
The mass-metallicity relation (MZR) represents one of the most important scaling relations in the context of galaxy evolution, comprising a positive correlation between stellar mas…
