Ionized Gas in the Irr Galaxy IC 10: The Emission Spectrum and Ionization Sources
V. P. Arkhipova, O. V. Egorov, T. A. Lozinskaya +1
We present the results of observations of the Irr galaxy IC 10 at the 6-m SAO telescope with the panoramic Multi-Pupil Fiber Spectrograph (MPFS). Based on the results of these obse…
Properties and Structural Features of Early-type Disk Galaxies with Multi-tier Disks
Marina A. Ilyina, Olga K. Sil'chenko
The results of photometric decomposition of surface brightness distributions in 85 early-type unbarred galaxies are presented. The SDSS r-images are analysed. Double-tiered exponen…
A tale of two GRB-SNe at a common redshift of z = 0.54
Z. Cano, D. Bersier, C. Guidorzi +71
We present ground-based and HST optical observations of the optical transients (OTs) of long-duration Gamma Ray Bursts (GRBs) 060729 and 090618, both at a redshift of z = 0.54. For…
Galactic disks and their evolution
A. V. Zasov, O. K. Sil'chenko
We consider the key problems related to measuring the mass of stellar disks and dark halos in galaxies and to explaining the observed properties of disks formed in massive dark hal…
Galactic chemical evolution in hierarchical formation models - II. The Intracluster Medium
Matías Arrigoni, Scott C. Trager, Rachel S. Somerville
We use the cosmological semi-analytic model (SAM) for galaxy formation presented in Paper I to study the metallicities and abundance ratios of the intracluster medium (ICM) within…
Star Formation History in the Central Region of the Barred Galaxy NGC 7177
Olga K. Sil'chenko, Aleksandrina A. Smirnova
Using the method of integral-field (3D) spectroscopy, we have investigated the kinematics and distribution of the gas and stars at the center of the early-type spiral galaxy with a…
The nature of proximate damped Lyman alpha systems
Sara L. Ellison, J. Xavier Prochaska, Joseph Hennawi +5
We present high resolution echelle spectra of 7 proximate damped Lyman alpha (PDLA) systems whose relative velocity separation from the background quasar is Delta V < 3000 km/s. Co…
Quasar variability limits on cosmological density of cosmic strings
Artem Tuntsov, Maxim Pshirkov
We put robust upper limits on the average cosmological density Ω_s of cosmic strings based on the variability properties of a large homogeneous sample of SDSS quasars. We search fo…
