Li - O anti-correlation in NGC 6752: evidence for Li-enriched polluting gas
stars abundances – globular clusters individual NGC6752 – stars late-type
2010/11/11
Context. Elemental correlations and anti-correlations are known to be present in globular clusters (GCs) owing to pollution by CNO cycled gas. Because of its fragility Li is destroyed at the temperatu...
The Global Gas and Dust budge of the Large Magellanic Cloud --- Importance of Asymptotic Giant Branch stars
The Global Gas Large Magellanic Cloud
2010/11/11
It is still an unresolved problemhowmuch AGB stars can contribute to the overall gas and dust enrichment processes in the interstellar medium within galaxies.We start tackling this problem, by using o...
A2163: Merger events in the hottest Abell galaxy cluster II. Subcluster accretion with galaxy-gas separation
Galaxies clusters general – Galaxies intergalactic medium – X-rays galaxies clusters
2010/11/16
Located at z = 0.203, A2163 is a rich galaxy cluster with an intra-cluster medium (ICM) that exhibits extraordinary properties,including an exceptionally high X-ray luminosity, average temperature, an...
The rates and modes of gas accretion on to galaxies and their gaseous haloes
galaxies evolution – galaxies formation – intergalactic medium – cos-mology theory
2010/11/15
We study the rate at which gas accretes on to galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures before reaching a galaxy.For this purpose we use a suite of ...
Active Disk Building in a local HI-Massive LIRG: The Synergy between Gas, Dust, and Star Formation
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/7
HIZOA J0836-43 is the most HI-massive (M_HI = 7.5x10^10 Msun) galaxy detected in the HIPASS volume and lies optically hidden behind the Milky Way. Markedly different from other extreme HI disks in 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.
On the evolution of intra-cluster gas within Galactic globular clusters
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2010/12/27
It has been known since the 1950's that the observed gas content of Galactic globular clusters (GCs) is 2-3 orders of magnitude less than the mass lost by stars between Galactic disk crossings.

A Self-similar Flow Behind a Shock Wave in a Gravitating or Non-gravitating Gas with Heat Conduction and Radiation Heat-flux
Shock wave self-similar flow self-gravitational effects heat transfer effects variable initial density variable total energy
2010/9/15
The propagation of a spherical shock wave in an ideal gas with heat conduction and radiation heat-flux, and with or without self-gravitational effects, is investigated. The initial density of the gas ...
