Disc-halo gas outflows driven by stellar clusters as seen in multiwavelength tracers

Autor: Vasiliev, Evgenii O., Drozdov, Sergey A., Nath, Biman B., Dettmar, Ralf-Jürgen, Shchekinov, Yuri A.

We consider the dynamics of and emission from growing superbubbles in a stratified interstellar gaseous disc driven by energy release from supernovae explosions in stellar clusters with {masses $M_{cl}= 10^5-1.6\times 10^6~M_\odot$}. Supernovae are s

Dust-free starburst galaxies at redshifts $z>10$

Autor: Nath, Biman B., Vasiliev, Evgenii O., Drozdov, Sergey A., Shchekinov, Yuri A.

One of the most distant galaxies GN-z11 was formed when the Universe was $\le$ 400 Myr old, and it displays a burst-like star formation rate $\sim 25~M_\odot$ yr$^{-1}$ with a metallicity $Z\sim 0.2\pm 0.1Z_\odot$. It resembles $z=2-3$ galaxies (at `

Bubbles and OB associations

Autor: Drozdov Sergey A., Vasiliev Evgenii O., Ryabova Marina V., Shchekinov Yuri A., Nath Biman B.

Publikováno v: Open Astronomy, Vol 31, Iss 1, Pp 154-165 (2022)

Supernovae explosions (SNe) in a stratified interstellar disc can create large scale structures and outflows perpendicular to the disc. Their morphology and emission characteristics depend on interrelations between the number of exploded SNe, the ISM

Hα emission from gaseous structures above galactic discs

Autor: Vasiliev Evgenii O., Drozdov Sergey A., Shchekinov Yuri A.

Publikováno v: Open Astronomy, Vol 31, Iss 1, Pp 99-105 (2022)

Extraplanar structures of ionized gas are detected in numerous edge-on galaxies. Whether HII regions or supernovae (SNe) responsible for its ionization is still debated. Here, we consider the Hα{\rm{H}}\alpha emissivity from shells of superbubbles d

Investigation of the force effect of the vibrating working body of the slitter on the soil

Autor: Konstantinov Mikhail, Drozdov Sergey, Mukhamedov Vitaly, Nuralin Beket, Galiev Manarbek

Publikováno v: E3S Web of Conferences, Vol 193, p 01003 (2020)

The theory of the force action of the working body of the slitter on the ground is considered. It is proposed to divide this force into four components: the force of cutting the material, the force of overcoming the friction forces acting on the grou

Russian Revolution: triumph or tragedy?

Autor: Drozdov Sergey Valentinovich

Publikováno v: Studia Humanitatis, Vol 1 (2017)

The present paper focuses on the most important events that happened in Petrograd from February to October 1917 and radically changed the whole character of the country. The paper also deals with their participants’ actions which turned out to be c
