Detection of an intergalactic meteor particle with the 6-m telescope
V. L. Afanasiev, V. V. Kalenichenko, I. D. Karachentsev
On July 28, 2006 the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences recorded the spectrum of a faint meteor. We confidently identify the…
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…
Young Nuclei in Dwarf Elliptical Galaxies
Igor Chilingarian, Olga Sil'chenko, Victor Afanasiev +1
We report discovery of young embedded structures in three diffuse elliptical galaxies (dE) in the Virgo cluster: IC 783, IC 3468, and IC 3509. We performed 3D spectroscopic observa…
Ages, Metallicities, and [alpha/Fe] ratios of globular clusters in NGC 147, NGC 185, and NGC 205
M. E. Sharina, V. L. Afanasiev, T. H. Puzia
We present measurements of ages, metallicities, and [alpha/Fe] ratios for 16 globular clusters (GC) in NGC 147, NGC 185, and NGC 205 and of the central regions of the diffuse galax…
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…
Integral field spectroscopy of the ultraluminous X-ray source Holmberg II X-1
I. Lehmann, T. Becker, S. Fabrika +10
We present optical integral field observations of the H II region containing the ultraluminous X-ray source Holmberg II X-1. We confirm the existence of an X-ray ionized nebula as…
