Extreme kinematic misalignment in IllustrisTNG galaxies: the origin, structure and internal dynamics of galaxies with a large-scale counterrotation
Sergey Khoperskov, Igor Zinchenko, Branislav Avramov +9
Modern galaxy formation theory suggests that the misalignment between stellar and gaseous components usually results from an external gas accretion and/or interaction with other ga…
Lagrange-Eulerian method for numerical integration of the gas dynamics equations: parallel implementation on GPUs
Sergey Khrapov, Alexander Khoperskov, Sergey Khoperskov
We describe a new CSPH-TVD method for numerical integration of hydrodynamical equations. The method is based on combined Lagrange-Euler approaches, and it has been devoted to simul…
A Malin 1 'cousin' with counter-rotation: internal dynamics and stellar content of the giant low surface brightness galaxy UGC 1922
Anna S. Saburova, Igor V. Chilingarian, Ivan Yu. Katkov +5
The formation scenario for giant low surface brightness (gLSB) galaxies with discs as large as 100 kpc still remains unclear. These stellar systems are rare and very hard to observ…
The study of two barred galaxies with curious kinematical features
A. S. Saburova, I. Yu. Katkov, S. A. Khoperskov +2
We performed long-slit spectral observations of two SB-type galaxies: NGC 5347, UGC 1344. They were previously suspected as the galaxies with unusually low mass-to-light ratios (on…
A Kennicutt-Schmidt relation at molecular cloud scales and beyond
Sergey A. Khoperskov, Evgenii O. Vasiliev
Using N-body/gasdynamic simulations of a Milky Way-like galaxy we analyse a Kennicutt-Schmidt relation, , at different spatial scales. We simulate synthe…
GMCs scaling relations: role of the cloud definition
S. A. Khoperskov, E. O. Vasiliev, D. A. Ladeyschikov +2
We investigate physical properties of molecular clouds in disc galaxies with different morphology: a galaxy without prominent structure, a spiral barred galaxy and a galaxy with fl…
Giant molecular clouds in M 33: are they susceptible to dynamical friction?
A. V. Zasov, S. A. Khoperskov
Most of giant molecular clouds (GMCs) in M 33 are connected with spiral-like gaseous arms (filaments) with the exception of the inner 2 kpc region where the link between the arms a…
Numerical code for multi-component galaxies: from N-body to chemistry and magnetic fields
S. A. Khoperskov, E. O. Vasiliev, A. V. Khoperskov +1
We present a numerical code for multi-component simulation of the galactic evolution. Our code includes the following parts: -body is used to evolve dark matter, stellar dynamic…
The simulation of molecular clouds formation in the Milky Way
S. A. Khoperskov, E. O. Vasiliev, A. M. Sobolev +1
Using 3D hydrodynamic calculations we simulate formation of molecular clouds in the Galaxy. The simulations take into account molecular hydrogen chemical kinetics, cooling and heat…
