Chemically Decoupled Nuclei in Five Lenticular Galaxies from SAURON Data

Sil'Chenko, O. K.

We analyze data from the SAURON integral-field spectrograph of the William Herschel 4-m telescope for five lenticular galaxies in which we previously found chemically decoupled nuclei from observations with the Multipupil Fiber Spectrograph of the 6-m Special Astrophysical Observatory telescope. In a larger field of view, we confirmed the presence…

New Observations of the Pulsar Wind Nebula in the Supernova Remnant CTB 80

Moiseev, A. V.; Blinnikov, S. I.; Lozinskaya, T. A. +1 more

We investigated the kinematics of the pulsar wind nebula (PWN) in the old supernova remnant CTB 80 using the Fabry-Perot interferometer of the 6-m Special Astrophysical Observatory telescope. In addition to the previously known expansion of the system of bright filaments with a velocity of 100 200 km s-1, we detected weak high-velocity features in…
