A new method for studying the blazar variability on the shortest time scales and its application to S5 1803+784

Autor: Butuzova, M. S., Guseva, V. A., Gorbachev, M. A., Krivenko, A. S., Nazarov, S. V.

Publikováno v: Journal of High Energy Astrophysics, Volume 45, March 2025, Pages 19-31

We propose a new method for investigating the evolution of the properties of the blazar brightness variability on timescales from a few hours to a few days. Its essence lies in detecting sequentially located time intervals along the entire light curv

Report

A negligible contribution of two luminous $z$ ~ 7.5 galaxies to the ionizing photon budget of reionization

Autor: Gazagnes, S., Chisholm, J., Endsley, Ryan, Berg, D. A., Leclercq, F., Jurlin, N., Saldana-Lopez, A., Finkelstein, S. L., Flury, S. R., Guseva, N. G., Henry, A., Izotov, Y. I., Jung, I., Matthee, J., Schaerer, D.

We present indirect constraints on the absolute escape fraction of ionizing photons ($f_{\rm esc}^{\rm LyC}$) of the system GN 42912 which comprises two luminous galaxies ($M_{\rm UV}$ magnitudes of -20.89 and -20.37) at $z\sim7.5$, GN 42912-NE and G

An Equilibrium Dynamic Traffic Assignment Model with Linear Programming Formulation

Autor: Guseva, Victoria, Sklonin, Ilya, Podlipnova, Irina, Yarmoshik, Demyan, Gasnikov, Alexander

In this paper, we consider a dynamic equilibrium transportation problem. There is a fixed number of cars moving from origin to destination areas. Preferences for arrival times are expressed as a cost of arriving before or after the preferred time at

Lagrangian flow networks for passive dispersal: tracers versus finite size particles

Autor: Valente, Deoclécio, Guseva, Ksenia, Feudel, Ulrike

The transport and distribution of organisms like larvae, seeds or litter in the ocean as well as particles in industrial flows is often approximated by a transport of tracer particles. We present a theoretical investigation to check the accuracy of t

Report

Run-away transition to turbulent strong-field dynamo

Autor: Guseva, Anna, Petitdemange, Ludovic, Tobias, Steven M.

Planets and stars are able to generate coherent large-scale magnetic fields by helical convective motions in their interiors. This process, known as hydromagnetic dynamo, involves nonlinear interaction between the flow and magnetic field. Nonlinearit
