Observations of Sy2 galaxy NGC 3281 by XMM-Newton and INTEGRAL satellites
Vasylenko, A. A.; Fedorova, E.; Zhdanov, V. I.
We present the results of the analysis of X-ray properties of the Seyfert 2 galaxy NGC 3281, based on the observational data obtained by XMM-Newton and INTEGRAL within the energy ranges 0.2-12 keV and 20-150 keV, respectively. The XMM-Newton spectrum of this object is presented for the first time. We show that fitting the X-ray spectrum of this ga…
Bright X-ray galaxies in SDSS filaments
Tugay, A. V.
Eighteen bright X-ray emitting galaxies were found in nearby filaments within the SDSS region. Basic X-ray spectral parameters were estimated for these galaxies using a power law model with photoelectric absorption. A close pair of X-ray galaxies was found.
Nonthermal emission model of isolated X-ray pulsar RX J0420.0-5022
Chkheidze, N.; Babyk, Iu.
In this paper, an alternative theoretical interpretation to the generally assumed thermal emission models of the observed X-ray spectrum of isolated pulsar RX J0420.0-5022 is presented. It is well-known that at a pulsar surface, the distribution function of relativistic particles is one-dimensional. However, cyclotron instability causes an appeara…
On the question of detecting granulation signal in CoRoT light curves of A and B stars
Ghazaryan, S.
We applied the procedure written by us to HgMn targets observed both through CoRoT astero and exo channels to check its usefulness for search of possible existence of solar-type granulation signature in their power spectrum. The point is that many articles appeared very recently considering this problem but, we did not find any paper on this issue…
