Superflare on a rapidly-rotating solar-type star captured in X-rays
Andrey Mukhin, Roman Krivonos, Ilfan Bikmaev +5
In this work, we studied X-ray source SRGe~J021932.4040154 (SRGe J021932), which we associated with a single X-ray active star of spectral class G2V-G4V and the rotational perio…

Strong limits on keV-scale galactic sterile neutrino dark matter with stray light from NuSTAR after 11 years of operation
R. A. Krivonos, V. V. Barinov, A. A. Mukhin +1
Using tremendous photon statistics gained with the stray light aperture of the NuSTAR telescope over 11 years of operation, we set strong limits on the emission of close to monochr…

Wavelet-based image decomposition method for NuSTAR stray light background studies
Andrey Mukhin, Roman Krivonos, Alexey Vikhlinin +3
The large side aperture of the NuSTAR telescope for unfocused photons (so-called stray light) is a known source of rich astrophysical information. To support many studies based on…
