Dust-Obscured Star-Formation in Intermediate Redshift Galaxy Clusters
Dust-Obscured Star-Formation Intermediate Redshift Galaxy Clusters
2011/1/11
We present Spitzer MIPS 24-micron observations of 16 0.4rawn from the ESO Distant Cluster Survey (EDisCS). This is the first large 24-micron survey of clusters at intermediate ...
The star formation history of the Large Magellanic Cloud as seen by star clusters and stars
galaxies evolution - galaxies: individual galaxies stellar content - galaxies star clusters
2010/11/10
The aim of this work is to test to what extent the star cluster population of a galaxy can be
utilised to constrain or estimate the star formation history, with the Large Magellanic Cloud as our test...
Towards the Rosetta Stone of planet formation
Earth and Planetary Astrophysics (astro-ph.EP)
2011/1/5
Transiting exoplanets (TEPs) observed just about 10 Myrs after formation of their host systems may serve as the Rosetta Stone for planet formation theories. They would give strong constraints on sever...
Many theoretical and laboratory studies predict H2 to be formed in highly excited ro-vibrational states. The consequent relaxation of excited levels via a cascade of infrared transitions might be obse...
Star formation in the Taurus filament L1495: From Dense Cores to Stars
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We present a study of dense structures in the L1495 filament in the Taurus Molecular Cloud and examine its star-forming properties. In particular we construct a dust extinction map of the filament usi...
The formation of polycyclic aromatic hydrocarbons in evolved circumstellar environments
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2011/1/4
The formation of Polycyclic Aromatic Hydrocarbons in the circumstellar outflows of evolved stars is reviewed, with an emphasis on carbon stars on the Asymptotic Giant Branch. Evidence for PAHs present...
The Decrease of Specific Angular Momentum and the Hot Toroid Formation: The Massive Clump G10.6-0.4
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
This is the first paper of our series of high resolution (1") studies of the massive star forming region G10.6--0.4. We present the emission line observations of the hot core type tracers (O$^{13}$CS,...
Dust emission and star formation in Stephan's Quintet
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We analyse a comprehensive set of MIR/FIR observations of Stephan's Quintet (SQ), taken with the Spitzer Space Observatory. Our study reveals the presence of a luminous (L_{IR}\approx 4.6x10^43 erg/s)...
A closer view of the radio-FIR correlation: disentangling the contributions of star formation and AGN activity
Galaxy Astrophysics (astro-ph.GA)
2010/12/23
We extend the Unified Radio Catalog, a catalog of sources detected by various (NVSS, FIRST, WENSS, GB6) radio surveys, and SDSS, to IR wavelengths by matching it to the IRAS Point and Faint Source cat...
