GW190814 was a compact object binary coalescence detected in gravitational waves by
Advanced LIGO and Advanced Virgo that garnered exceptional community interest due to its …

Context. Observations have shown that inner discs and rings (IDs and IRs) are not
preferably found in barred galaxies, which indicates that their formation may differ from that …

General structural properties and low surface brightness tidal features hold important clues
to the formation of galaxies. In this paper, we study a sample of polar-ring galaxies (PRGs) …

In the latest ten years, a big effort has given to study the morphology and kinematics of polar
ring galaxies: many steps forward and new discoveries on the structure and formation …

Polar ring galaxies, where matter is in equilibrium in perpendicular orbits around spiral
galaxies, are ideal objects to probe the 3D shapes of dark matter halos. The conditions to …

We present a photometric study of PGC 1000714, a galaxy resembling Hoag's Object with a
complete detached outer ring, that has not yet been described in the literature. Since the …

We present a detailed photometric study of the peculiar double-ringed galaxy ESO 474−
G26. Near-infrared (NIR) and optical data have been used, with the main goal of …

The linear theory and N-body simulations are used to present a new, alternative model of
the galaxy A0035-324 (the “Cartwheel”), which is the most striking example of the relatively …

In this paper, we present a detailed study of the peculiar early-type galaxy NGC 1947. The
main goal of this work is to constrain the dynamical status and the formation history of NGC …
