The Properties of Type Ia Supernova Host Galaxies from the Sloan Digital Sky Survey
galaxies fundamental parameters — galaxies statistics — supernovae general
2010/11/12
We investigate the properties and environments of Type Ia Supernova (SN Ia) host galaxies in
the Stripe 82 of the Sloan Digital Sky Survey-II Supernova Survey centered on the celestial equator.Host g...
Fundamental Properties of the Highly Ionized Plasmas in the Milky Way
Galaxy disk — ISM Clouds — ISM structure — ultraviolet ISM
2010/11/15
The cooling transition temperature gas in the interstellar medium (ISM), traced by the high ions,Si IV, C IV, N V and O VI, helps to constrain the flow of energy from the hot ISM with T > 106 K to the...
Molecular gas properties of galaxies: The SMA CO(2-1) B0DEGA legacy project
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
In the last two decades high resolution (< 5 arcsec) CO observations for ~ 150 galaxies have provided a wealth of information about the molecular gas morphologies in the circumnuclear regions.
Statistical study of dust properties in LMC molecular clouds
Galaxy Astrophysics (astro-ph.GA)
2011/1/5
The objective of this paper is to construct a catalog providing the dust properties and the star formation efficiency (SFE) of the molecular clouds in the Large Magellanic Cloud (LMC). We use the infr...
The Properties of X-ray Cold Fronts in a Statistical Sample of Simulated Galaxy Clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
We examine the incidence of cold fronts in a large sample of galaxy clusters extracted from a (512h^-1 Mpc) hydrodynamic/N-body cosmological simulation with adiabatic gas physics computed with the Enz...
Infrared properties of Active OB stars in the Magellanic Clouds from the Spitzer SAGE Survey
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We present a study of the infrared properties of 4922 spectroscopically confirmed massive stars in the Large and Small Magellanic Clouds, focusing on the active OB star population. Besides OB stars, o...
