Characterizing Distant Galaxies: Spectral Energy Distribution Analysis of X-ray Selected Star Forming Galaxies
galaxies - fundamental parameters Galaxies - high redshift Galaxies - submillimeter methods - statistical
2014/12/9
Comprehensive and robust analysis of galaxies found throughout cosmic time provides the means to probe the underlying characteristics of our Universe. Coupling observations and theory, spectral energy...
Oscillations of relativistic axisymmetric tori and implications for modelling kHz-QPOs in neutron-star X-ray binaries
X-rays: binaries – relativity – stars: neutron
2011/10/8
We perform a global linear perturbative analysis, and investigate the oscillation properties of relativistic, non-selfgravitating tori orbiting around neutron stars in the slow rotation limit approxim...
Variability of C III and Si III lines in the ultraviolet spectral region of the magnetic Bp star a Centauri
Variability ultraviolet spectral region magnetic Centauri
2011/9/30
The variability of twice ionized lines of carbon and silicon in the ultraviolet spectral region of the magnetic Bp star a Centauri is investigated. This study is based on the archival {\it Internation...

We report the discovery and detailed monitoring of X-ray emission associated with the Type IIb SN 2011dh using data from the Swift and Chandra satellites, placing it among the best studied X-ray super...
We report the results of a recent study of young star clusters (YSCs) in luminous blue compact galaxies (BCGs). The age distributions of the YSCs suggest that the starburst episode in Haro 11, ESO 185...

Chemistry of Carbon Rich Star IRAS 15194–5115
Molecular data—molecular processes—stars AGB—stars individual IRAS 15194–5115
2010/9/16
We have constructed two gas-phase models to study the chemistry of circumstellar envelope surrounding the carbon-rich variable star IRAS 15194–5115. The network used consists of 3893 reactions involvi...
