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…

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…

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…

Edge-on galaxies in the HST COSMOS field: the evolution of stellar discs up to z0.5

P. A. Usachev, V. P. Reshetnikov, S. S. Savchenko

We present a sample of 950 edge-on spiral galaxies found with the use of an artificial neural network in the Hubble Space Telescope COSMOS field. This is currently the largest samp…

Search for the edge-on galaxies using an artificial neural network

S. S. Savchenko, D. I. Makarov, A. V. Antipova +1

We present an application of an artificial neural network methodology to a modern wide-field sky survey Pan-STARRS1 in order to build a high-quality sample of disk galaxies visible…

The problem of dust attenuation in photometric decomposition of edge-on galaxies and possible solutions

Sergey Savchenko, Denis Poliakov, Aleksandr Mosenkov +6

The presence of dust in spiral galaxies affects the ability of photometric decompositions to retrieve the parameters of their main structural components. For galaxies in an edge-on…

Barless flocculent galaxies: a dynamic puzzle

Daria Zakharova, Natalia Ya. Sotnikova, Anton A. Smirnov +1

We draw attention to the bright galaxies that do not show a bar in their structure but have a flocculent spiral structure. Using the THINGS' and HERACLES' kinematic data for four b…

Discovery of X-ray polarization angle rotation in active galaxy Mrk 421

Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert +140

The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can trac…

The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics

C. M. Raiteri, M. Villata, S. G. Jorstad +13

In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…

A Three-Dimensional Analytical Model of the Interstellar Extinction within the Nearest Kiloparsec

G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6

We present a new version of our analytical model of the spatial interstellar extinction variations within the nearest kiloparsec. This model treats the 3D dust distribution as a su…

Prospects for future studies using deep imaging: Analysis of individual Galactic cirrus filaments

Anton A. Smirnov, Sergey S. Savchenko, Denis M. Poliakov +6

The presence of Galactic cirrus is an obstacle for studying both faint objects in our Galaxy and low surface brightness extragalactic structures. With the aim of studying individua…
