Diffraction-limited 76 mas Speckle Masking Observations of the Core of NGC 1068 with the SAO 6m Telescope
M. Wittkowski, Y. Balega, T. Beckert +3
We present the first K-band bispectrum speckle interferometry of NGC 1068 with an angular resolution of 76 mas (~5.5pc). This angular resolution allows us to attribute the measured…
Spectral Observations of Faint Markarian Galaxies of the Second Byurakan Survey. II
L. Carrasco, H. M. Tovmassian, J. A. Stepanian +3
We continue the program of spectroscopic observations of objects from the Second Byurakan Survey (SBS). This survey contains more than 1300 galaxies and 1700 star-like objects with…
Did GRB 970228 and GRB 970508 present similar optical properties?
C. Bartolini, G. M. Beskin, A. Guarnieri +2
The analysis of the light curves of the optical counterparts of GRB 970228 and GRB 970508 points out remarkable similarities. The spectral distribution obtained from the color indi…
Optical spectrum of the IR-source IRC+10420 in 1992-1996
V. G. Klochkova, E. L. Chentsov, V. E. Panchuk
To understand the evolutionary stage of the peculiar supergiant IRC+10420, we have been taking spectra for several years at the 6m telescope. The optical spectrum of IRC+10420 of t…
Multicolor photometry of the GRB970508 optical remnant
V. V. Sokolov, A. I. Kopylov, S. V. Zharikov +5
We report results of follow-up multicolor photometry of the optical variable source that is a probable remnant of the gamma-ray burst GRB970508 discovered by the BeppoSAX satellite…
Deep photometric study of the region of the gamma-ray burst localization of June 13, 1979
V. V. Sokolov, V. G. Kurt, S. V. Zharikov +2
In the framework of the hypothesis on potential sources of some gamma-ray bursts being single compact objects of neutron star type with finite surface temperature in the vicinity o…
