A Deep View into the Nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. III. Discrete multi-component population-dynamical models based on the Jeans equations
Nikolay Kacharov, Mayte Alfaro-Cuello, Nadine Neumayer +12
We present comprehensive multi-component dynamical models of M54 (NGC6715), the nuclear star cluster of the Sagittarius dwarf galaxy (Sgr), which is undergoing a tidal disruption i…
Recovering age-metallicity distributions from integrated spectra: validation with MUSE data of a nearby nuclear star cluster
A. Boecker, M. Alfaro-Cuello, N. Neumayer +2
Current instruments and spectral analysis programs are now able to decompose the integrated spectrum of a stellar system into distributions of ages and metallicities. The reliabili…
A deep view into the nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. II. Kinematic characterization of the stellar populations
Mayte Alfaro-Cuello, Nikolay Kacharov, Nadine Neumayer +9
The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is in an advanced stage of disruption but still hosts its nuclear star cluster (NSC), M54, at its center. In this paper, we prese…
Light element variations within the different age-metallicity populations in the nucleus of the Sagittarius dwarf
Alison Sills, Emanuele Dalessandro, Mario Cadelano +2
The cluster M54 lies at the centre of the Sagittarius dwarf spheroidal galaxy, and therefore may be the closest example of a nuclear star cluster. Either in-situ star formation, in…
A deep view into the nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. I. Data and stellar population characterization
Mayte Alfaro-Cuello, Nikolay Kacharov, Nadine Neumayer +9
The center of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) hosts a nuclear star cluster, M54, which is the only galaxy nucleus that can be resolved into individual stars at o…
Constraining nuclear star cluster formation using MUSE-AO observations of the early-type galaxy FCC47
Katja Fahrion, Mariya Lyubenova, Glenn van de Ven +12
Nuclear star clusters (NSCs) are found in at least 70% of all galaxies, but their formation path is still unclear. In the most common scenarios, NSCs form in-situ from the galaxy's…
