Optical Spectroscopy of the ULX-Associated Nebula MF16
Pavel Abolmasov, S. Fabrika, O. Sholukhova +1
We present the results of optical panoramic and long-slit spectroscopy of the nebula MF16 associated with the Ultraluminous X-ray Source NGC6946 ULX-1. More than 20 new emission li…
Kinematics of the Nebular Complex MH9/10/11 Associated with HoIX X-1
P. Abolmasov, A. V. Moiseev
We report the results of our observations of the nebular complex MH9/10/11, associated with the ULX HoIX X-1, with scanning Fabry-Perot Interferometer. Two regions differing by the…
Optical Spectroscopy of the environment of a ULX in NGC 7331
Pavel K. Abolmasov, Douglas A. Swartz, S. Fabrika +3
Optical photometric and spectroscopic data are presented that show an association of an ultraluminous X-ray source in NGC 7331 with a young star cluster of mass 1.1e5 solar masses…
Observation Campaign of SS 433 in April 2006
T. Kotani, K. Kubota, M. Namiki +19
A radio-IR-optical-X-ray observation campaign of SS 433 has been performed in April 2006, when the jet axis is almost perpendicular to the line of sight. Five flares have been dete…
Super-critically accreting stellar-mass black holes as ultraluminous X-ray sources
Juri Poutanen, Galina Lipunova, Sergei Fabrika +2
We derive the luminosity-temperature relation for the super-critically accreting black holes (BHs) and compare it to the data on ultraluminous X-ray sources (ULXs). At super-Edding…
Intergal field spectroscopy survey of classical LBV stars in M33
O. Sholukhova, P. Abolmasov, S. Fabrika +2
Five well-known LBV stars in M33 were observed with the Multi-Pupil Fiber Spectrograph (MPFS) on the 6-m Russian telescope. We observed LBVs varA, varB, varC, var2 and var83. In th…
