The central mass and mass-to-light profile of the Galactic globular cluster M15
Mark den Brok, Glenn van de Ven, Remco van den Bosch +1
We analyze line-of-sight velocity and proper motion data of stars in the Galactic globular cluster M15 using a new method to fit dynamical models to discrete kinematic data. Our fi…
Discrete dynamical modelling of omega Centauri
Laura L. Watkins, Glenn van de Ven, Mark den Brok +1
We present a new framework for modelling discrete kinematic data. Current techniques typically involve binning. Our approach works directly with the discrete data and uses maximum-…
Bottom-heavy initial mass function in a nearby compact L*-galaxy
Ronald Läsker, Remco C. E. van den Bosch, Glenn van de Ven +4
We present orbit-based dynamical models and stellar population analysis of galaxy SDSS J151741.75-004217.6, a low-redshift (z=0.116) early-type galaxy (ETG) which, for its moderate…
The complex nature of the nuclear star cluster in FCC 277
Mariya Lyubenova, Remco C. E. van den Bosch, Patrick Cote +6
Recent observations have shown that compact nuclear star clusters (NSCs) are present in up to 80% of galaxies. However, detailed studies of their dynamical and chemical properties…
The VIRUS-P Exploration of Nearby Galaxies (VENGA): Survey Design, Data Processing, and Spectral Analysis Methods
Guillermo A. Blanc, Tim Weinzirl, Mimi Song +14
We present the survey design, data reduction, and spectral fitting pipeline for the VIRUS-P Exploration of Nearby Galaxies (VENGA). VENGA is an integral field spectroscopic survey,…
