Deep imaging with Milanković telescope: Linking merger history to kinematics of elliptical galaxies
Ivana Ebrová, Michal Bílek, Ana Lalović +4
Kinematical and morphological features observed in early-type galaxies provide valuable insights into the evolution of their hosts. We studied the origin of prolate rotation (i.e.,…

Origin of the spectacular tidal shells of galaxy NGC474
Michal Bílek, Jérémy Fensch, Ivana Ebrová +4
The lenticular galaxy NGC474 hosts a rich system of tidal shells and streams, some of which are exceptionally bright. Two teams recently presented spectroscopic observations of the…
