Adiabatic Spectrum of Radio Emission of Plasma Clouds, Emitted by the Sun During Solar Flares, and Inhomogeneities of the Spectrum of Radio Emission of Clouds
AbstractIt is known that so-called solar flares systematically occur in the area of sunspots. They are accompanied by radiation in almost all...

Radio Emission Spectrum of Supernova Remnant G74.9+1.2
AbstractMeasurements of the flux densities of the supernova remnant (SNR) G74.9+1.2 (CTB 87) at frequencies of 4840 and 8450 MHz were carried out...

X-ray emission spectrum for axion–photon conversion in magnetospheres of strongly magnetized neutron stars
Detecting axionic dark matter (DM) could be possible in an X-ray spectrum from strongly magnetized neutron stars (NSs). We examine the possibility of...

Search for Pre-Burst Emission from Binary Neutron Star Mergers with Spectrum–Roentgen–Gamma
AbstractClose binary systems consisting of two neutron stars (BNS) emit gravitational waves, that allow them to merge on timescales shorter than...
