Discovery of An X-ray Photoionized Optical Nebula and A Radio Nebula Associated with the ULX NGC 4861 X-1
Hang Gong, Ryan Urquhart, Alexandr Vinokurov +5
We have conducted long-slit spectroscopic observations and analyzed archival radio data for the ultraluminous X-ray source (ULX) NGC 4861 X-1. Our spectral line analysis unveils th…
Modeling of extended atmospheres with temperatures below 40000K
A. Kostenkov, A. Vinokurov, Y. Solovyeva +2
We calculate models of extended stellar atmospheres with a temperature in the range of 12000-40000K and a mass loss rate of yr. A large number of…
NuSTAR and Swift observations of the ultraluminous X-ray source IC 342 X-1 in 2016: witnessing spectral evolution
Megumi Shidatsu, Yoshihiro Ueda, Sergei Fabrika
We report on an X-ray observing campaign of the ultraluminous X-ray source IC 342 X-1 with NuSTAR and Swift in 2016 October, in which we captured the very moment when the source sh…
X-ray radiation of the jets and the supercritical accretion disk in SS 433
S. Fabrika, A. Medvedev
The observed X-ray luminosity of SS 433 is ~10^36 erg/s, it is known that all the radiation is formed in the famous SS 433 jets. The bolometric luminosity of SS 433 is ~10^40 erg/s…
Evidences of the supercritical disc funnel radiation in X-ray spectra of SS 433
A. Medvedev, S. Fabrika
We have analysed the XMM-Newton spectra of SS 433 using a standard model of adiabatically and radiatively cooling X-ray jets. The multi-temperature thermal jet model reproduces wel…
