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…
Analysis of Galactic cirrus filaments in HSC-SSP high-resolution deep images using artificial neural networks
Denis M. Poliakov, Anton A. Smirnov, Sergey S. Savchenko +6
The existence of Galactic optical cirrus poses a challenge for observing faint objects within our Galaxy and dim extragalactic structures. To investigate individual cirrus filament…
Boxy/Peanut Bulges: Comparative Analysis of EGIPS Galaxies and TNG50 Models
Anton Smirnov, Alexander Marchuk, Viktor Zozulia +2
We investigated the properties of boxy/peanut-shaped (B/PS) bulges in a sample of 71 galaxies from the Edge-on Galaxies in the Pan-STARRS Survey (EGIPS) and 20 simulated galaxies f…
