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…
Isochrone Fitting of Galactic Globular Clusters -- VII. NGC1904 (M79), NGC4372, and revision of NGC288, NGC362, NGC5904 (M5), NGC6205 (M13), and NGC6218 (M12)
George A. Gontcharov, Sergey S. Savchenko, Olga S. Ryutina +8
We estimate key parameters for the Galactic globular clusters NGC1904 and NGC4372 and update the parameters for NGC288, NGC362, NGC5904, NGC6205, and NGC6218, which were analysed i…
Phase-space distortion as a key to unraveling galactic bar buckling
Viktor D. Zozulia, Natalia Ya. Sotnikova, Anton A. Smirnov
For the first time, we investigate the resonant structure of -body galactic bar at the stage of buckling using action-angle variables. We studied the evolution of vertical actio…
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…
Boxy/peanut shaping of a mature galactic bar in action-angle space
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova +1
We study vertical resonant trapping and resonant heating of orbits. These two processes both lead to the growth of a boxy/peanut-shaped bulge in a typical -body model. For the f…
Isochrone Fitting of Galactic Globular Clusters -- VI. High-latitude Clusters NGC5024 (M53), NGC5053, NGC5272 (M3), NGC5466, and NGC7099 (M30)
G. A. Gontcharov, S. S. Savchenko, A. A. Marchuk +7
We fit various colour-magnitude diagrams (CMDs) of the high-latitude Galactic globular clusters NGC\,5024 (M53), NGC\,5053, NGC\,5272 (M3), NGC\,5466, and NGC\,7099 (M30) by isochr…
Positive Lynden-Bell derivative as a ticket to the bar trap?
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova
We have translated the results of -body simulations of one barred model into the language of action variables and frequencies. Using this language, we analysed the behaviour of…
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…
Isochrone fitting of Galactic globular clusters -- V. NGC6397 and NGC6809 (M55)
George A. Gontcharov, Charles J. Bonatto, Olga S. Ryutina +8
We fit various colour-magnitude diagrams (CMDs) of the Galactic globular clusters NGC\,6397 and NGC\,6809 (M55) by isochrones from the Dartmouth Stellar Evolution Database (DSED) a…
B/PS bulges and barlenses from a kinematic viewpoint. II
Daria Zakharova, Iliya S. Tikhonenko, Natalia Ya. Sotnikova +1
Internal dynamics and kinematics of galaxies have imprints on the line-of-sight velocity distribution~(LOSVD). Gauss-Hermite parametrisation allows one to identify the kinematics f…
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…
Globular clusters and bar: captured or not captured?
Anton A. Smirnov, Anisa T. Bajkova, Vadim V. Bobylev
Studies of the dynamics of globular clusters assume different values of bar parameters (mass, velocity, size) and analyse the results of orbit classifications over the range of the…
B/PS bulges and barlenses from a kinematic viewpoint. I
Daria Zakharova, Iliya S. Tikhonenko, Natalia Ya. Sotnikova +1
A significant part of barred disc galaxies exhibits boxy/peanut-shaped structures (B/PS bulges) at high inclinations. Another structure also associated with the bar is a barlens, o…
Tilted outer and inner structures in edge-on galaxies?
Aleksandr V. Mosenkov, Anton A. Smirnov, Olga K. Sil'chenko +3
Tilted and warped discs inside tilted dark matter haloes are predicted from numerical and semi-analytical studies. In this paper, we use deep imaging to demonstrate the likely exis…
The Halos and Environments of Nearby Galaxies (HERON) II: The outer structure of edge-on galaxies
Aleksandr Mosenkov, R. Michael Rich, Andreas Koch +6
The HERON project is aimed at studying halos and low surface brightness details near galaxies. In this second HERON paper we consider in detail deep imaging (down to surface bright…
What determines the flatness of X-shaped structures in edge-on galaxies
Anton A. Smirnov, Natalia Ya. Sotnikova
Recent observational studies of X-shaped structures revealed that values of their opening angles lie in a narrow range: from 20 deg to 43 deg with smaller X-shaped structures appea…
