Kinematics and Dynamics of Galaxies in Compact Groups for a sample of 31 groups

Astrophysics and Space Science, 2002
A long-term program based on Fabry-Perot Ha velocity field data of compact groups has been undertaken in order to analyse the kinematics of the compact group galaxies and the extent of their dark halos. The data are taken at the ESO and the CFH 3.6 m telescopes.

Stellar Kinematics and Dynamical Modeling of Two Seyfert Galaxies

2023
A crucial breakthrough in the study of galaxy evolution occurred with the discovery that black holes are ubiquitous in galaxy nuclei, and the masses of supermassive black holes scale with several properties of the host galaxies. The interpretation is that central black holes and their host galaxies co-evolve and regulate one anothers growth.

DARK MATTER OR MODIFIED DYNAMICS? HINTS FROM GALAXY KINEMATICS

Dark Matter in Astrophysics and Particle Physics, 2009
I show two observational projects I am involved in, which are aimed at understanding better the existence and nature of dark matter, and also aimed at testing alternatives to galactic dark matter such as MOND (Modified Newtonian Dynamics). I present new HI observations of the nearby dwarf galaxy NGC 3741.

The Dynamics and kinematics of galaxies in the Universe's Middle Ages

The evolutionary pathways a galaxy can follow are many and varied. Across billions of years of cosmic history, galaxies can experience numerous in situ and ex situ processes, each of which can leave a mark on their internal mass distribution and stellar kinematics.
