Published in 2021 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab3705

Abstract: Velocity dispersion (σ) is a key driver for galaxy structure and evolution. We here present a comprehensive semi-empirical approach to compute σ via detailed Jeans modelling assuming both a constant and scale-dependent mass-to-light ratio M*/L.… read more here.

Published in 2017 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stx1114

Abstract: The internal dynamics of globular clusters (GCs) is strongly affected by two-body interactions that bring the systems to a state of partial energy equipartition. Using a set of Monte Carlo clusters simulations, we investigate the… read more here.

Published in 2017 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stx1573

Abstract: We analyse the stellar kinematics of the z = 0.169 brightest cluster galaxy in Abell 1201, using integral field observations acquired with the Multi-Unit Spectroscopic Explorer on the Very Large Telescope. This galaxy has a… read more here.

Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty523

Abstract: Mass models of a sample of 171 low- and high-surface brightness galaxies are presented in the context of the cold dark matter (CDM) theory using the NFW dark matter halo density distribution to extract a… read more here.
