Projection-Enhanced Disk Breaks: Evidence from Deep Photometric Decomposition
Sergey S. Savchenko, Ilia V. Chugunov, Alexander A. Marchuk +5
Radial brightness profiles of disk galaxies often exhibit so-called breaks -- locations where their exponential-scale length abruptly changes. Some galaxies have downbending (Type…
The Edge-on Galaxies in the DESI survey (EGIDE): sample building and photometry
Alexander A. Marchuk, Sergey S. Savchenko, Dmitry I. Makarov +7
We present the EGIDE (The Edge-on Galaxies in the DESI survey) project - a catalogue of 149,215 edge-on galaxy candidates created using the data of the DESI Legacy Imaging Survey D…
A New Cartwheel-like Collisional Ring Galaxy
Vladimir P. Reshetnikov, Sergey S. Savchenko, Alexander A. Marchuk +5
We report the discovery of a new Cartwheel-type collisional ring galaxy, PGC\,1112751, which we named ``Eridanus Wheel'' (EW). Such systems result from head-on collisions between g…
Galactic warps: from cosmic noon to the current epoch
Vladimir P. Reshetnikov, Ilia V. Chugunov, Alexander A. Marchuk +6
Approximately half of all disc galaxies exhibit appreciable warps in both their stellar and HI discs. The typical warp amplitude is small (a few degrees), and only becomes noticeab…
