IMFIT-MW: Multiwavelength photometric decomposition with IMFIT
Ilia V. Chugunov
Photometric decomposition is often used to study galaxy structure by modelling surface brightness distribution in its components. However, most of the relevant codes are designed f…
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…
Clumps in spiral galaxies at : Disentangling two spatial modes of star formation
Ilia V. Chugunov, Alexander A. Marchuk
At high redshifts, star formation in galaxies is more often concentrated in clumps than in spiral arms. Although clumps are actively studied, it is rarely done considering spiral a…
Galactic disc warps from to modern epoch: ruling out observational effects
Ilia V. Chugunov, Vladimir P. Reshetnikov, Alexander A. Marchuk
A significant fraction of galaxies show warps in their discs, usually noticeable at its periphery. The exact origin of this phenomenon is not fully established, although multiple w…
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…
Examination of the functional form of the light and mass distribution in spiral arms
Ilia V. Chugunov, Alexander A. Marchuk, Sergey S. Savchenko
Spiral arms are a common feature of local galaxies, but the exact form of the distribution of mass and light in them is not well known. In this work, we aim to measure this distrib…
Accurate Decomposition of Galaxies with Spiral Arms: Dust Properties and Distribution
A. A. Marchuk, I. V. Chugunov, F. Galliano +8
We analyze three nearby spiral galaxies - NGC 1097, NGC 1566, and NGC 3627 - using images from the DustPedia database in seven infrared bands (3.6, 8, 24, 70, 100, 160, and 250 mic…
A Comprehensive Analysis on the Nature of the Spiral Arms in NGC 3686, NGC 4321, and NGC 2403
V. Kostiuk, A. Marchuk, A. Gusev +1
In theoretical investigations, various mechanisms have been put forward to explain the emergence of spiral patterns in galaxies. One of the few ways to find out the nature of spira…
Less Wound and More Asymmetric: JWST Confirms the Evolution of Spiral Structure in Galaxies at
Ilia V. Chugunov, Alexander A. Marchuk, Aleksandr V. Mosenkov
Spiral galaxies are ubiquitous in the local Universe. However the properties of spiral arms in them are still not well studied, and there is even less information concerning spiral…
Galaxies decomposition with spiral arms -- II: A multiwavelength case study of M 51
Alexander A. Marchuk, Ilia V. Chugunov, George A. Gontcharov +7
Spiral structure can contribute significantly to a galaxy's luminosity. However, only rarely are proper photometric models of spiral arms used in decompositions. As we show in the…
A multiwavelength study of spiral structure in galaxies. II. Spiral arms in deep optical observations
Aleksandr V. Mosenkov, Andrey D. Panasyuk, Savanah Turner +7
In this paper, we look to analyse the spiral features of grand-design, multiarmed, and flocculent spiral galaxies using deep optical imaging from DESI Legacy Imaging Surveys. We ex…
The possible evolution of pitch angles of spiral galaxies
V. P. Reshetnikov, A. A. Marchuk, I. V. Chugunov +2
The origin and maintenance of spiral structure in galaxies, the correlation between different types of spiral structure and several proposed mechanisms for their generation, and th…
Galaxies decomposition with spiral arms -- II: 29 galaxies from SG
Ilia V. Chugunov, Aleksandr V. Mosenkov, Alexander A. Marchuk +7
Spiral structure can occupy a significant part of the galaxy, but properly accounting for it in photometric decomposition is rarely done. This may lead to significant errors in the…
A new, purely photometric method for determination of resonance locations in spiral galaxies
Alexander A. Marchuk, Aleksandr V. Mosenkov, Ilia V. Chugunov +3
The knowledge of the positions of the corotation resonance in spiral arms is a key way to estimate their pattern speed, which is a fundamental parameter determining the galaxy dyna…
