Connecting traces of galaxy evolution: the missing core mass -- morphological fine structure relation

P. Bonfini, T. Bitsakis, A. Zezas +5

Deep exposure imaging of early-type galaxies (ETGs) are revealing the second-order complexity of these objects, which have been long considered uniform, dispersion-supported sphero…

Collisionless Boltzmann equation approach for the study of stellar discs within barred galaxies

Olivier Bienaymé

We study the kinematics of stellar disc populations within the solar neighbourhood in order to find the imprints of the Galactic bar. We carry out the analysis by developing a nume…

New constraints on quasar broad absorption and emission line regions from gravitational microlensing

Damien Hutsemékers, Lorraine Braibant, Dominique Sluse +2

Gravitational microlensing is a powerful tool allowing one to probe the structure of quasars on sub-parsec scale. We report recent results, focusing on the broad absorption and emi…
