Thick discs in galaxies were most likely not accreted
The origin of thick discs in galaxies remains shrouded in mystery. A variety of formation scenarios has been proposed. Here we aim to test one such scenario...
The detailed study of the different structural components of nearby galaxies can supply vital information about the secular, or internal, evolution of these...
Thick Disks seen in the Spitzer Survey of Stellar Structure in Galaxies
Most, if not all, disk galaxies have a thin (classical) disk and a thick disk. In most models thick disks are thought to be a necessary consequence of the disk...
Three Dimensional Structure of Penumbral Filaments from Hinode Observations
We analyze spectropolarimetric observations of the penumbra of the NOAA AR 10953 at high spatial resolution (0.3 ″ ). The full Stokes profiles of the Fe i lines...
Three eclipsing white dwarf plus main sequence binaries from SDSS
We identify SDSS 0110+1326, SDSS 0303+0054 and SDSS 1435+3733 as three eclipsing white dwarf plus main sequence binaries from the Sloan Digital Sky Survey, and...
The MASTER auto-detection system at Tunka (Baykal Lake) detected a new transient source at the position (R.A., Dec) = 17h 29m 00.07s , +75d 18m 42s.5, (J2000)...
