Gas of thin tubes of massless scalar field as a possible model of unified dark fluid
Alexander Lelyakov, Stepan Lelyakov
In this work, we investigated the influence of constants that characterize the motion of thin tubes of a massless scalar field (TToMSF) in a gas on the global properties of such a…
Nanometer thick magneto-optical iron garnet films
Nika Gribova, Sebastyan Osmanov, Sergey Lyashko +8
Here we demonstrate nanometer thick iron garnet films suitable for the magneto-optical applica-tions. Bismuth-substituted iron garnet films of compositions Bi{_1}Y{_2}Fe{_5}O{_{12}…
Subgradient methods for non-smooth optimization problems with some relaxation of sharp minimum
S. S. Ablaev, D. V. Makarenko, F. S. Stonyakin +2
In this paper we propose a generalized condition for a sharp minimum, somewhat similar to the inexact oracle proposed recently by Devolder-Glineur-Nesterov. The proposed approach m…
On the nature of the anomalous event in 2021 in the dwarf nova SS Cygni and its multi-wavelength transition
Mariko Kimura, Shinya Yamada, Nozomi Nakaniwa +20
SS Cyg has long been recognized as the prototype of a group of dwarf novae that show only outbursts. However, this object has entered a quite anomalous event in 2021, which at firs…
Multiperiodic magnetoplasmonic gratings fabricated by the pulse force nanolithography
Savelii V. Lutsenko, Mikhail A. Kozhaev, Olga V. Borovkova +7
We propose a novel technique for the magnetoplasmonic nanostructures fabrication based on the pulse force nanolithography method. It allows one to create the high-quality magnetopl…
A new method of measuring center-of-mass velocities of radially pulsating stars from high-resolution spectroscopy
N. E. Britavskiy, E. Pancino, V. Tsymbal +2
We present a radial velocity analysis of 20 solar neighborhood RR Lyrae and 3 Population II Cepheids variables. We obtained high-resolution, moderate-to-high signal-to-noise ratio…
