An unidentified line in X-ray spectra of the Andromeda galaxy and Perseus galaxy cluster
Alexey Boyarsky, Oleg Ruchayskiy, Dmytro Iakubovskyi +1
We report a weak line at 3.52+/-0.02 keV in X-ray spectra of M31 galaxy and the Perseus galaxy cluster observed by MOS and PN cameras of XMM-Newton telescope. This line is not know…
Potential of LOFT telescope for the search of dark matter
A. Neronov, A. Boyarsky, D. Iakubovskyi +1
Large Observatory For X-ray Timing (LOFT) is a next generation X-ray telescope selected by European Space Agency as one of the space mission concepts within the ``Cosmic Vision'' p…
Gravitational lens equation. Critical solutions and magnification near folds and cusps
A. N. Alexandrov, S. M. Koval, V. I. Zhdanov
We study approximate solutions of the gravitational lens equation and corresponding lens magnification factor near the critical point. This consideration is based on the Taylor exp…
