An Ultraviolet Spectroscopic Atlas of Local Starbursts and Star-Forming Galaxies: The Legacy of FOS and GHRS
line profiles atlases ultraviolet galaxies galaxies high-redshift galaxies
2010/11/9
We present 46 rest-frame ultraviolet (UV) spectra of 28 local starburst and star-forming galaxies which were observed with the Faint Object Spectrograph (FOS) and the Goddard High Resolution Spectrogr...
Dense molecular gas toward W49A: A template for extragalactic starbursts?
Dense molecular gas toward W49A extragalactic starbursts
2011/1/10
The HCN, HCO+, and HNC molecules are commonly used as tracers of dense star-forming gas in external galaxies, but such observations are spatially unresolved. Reliably inferring the properties of galac...
A Multiwavelength Study on the Fate of Ionizing Radiation in Local Starbursts
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
The fate of ionizing radiation is vital for understanding cosmic ionization, energy budgets in the interstellar and intergalactic medium, and star formation rate indicators. The low observed escape fr...
Dense Molecular Gas Excitation in Nuclear Starbursts at High Redshift: HCN, HNC, and HCO+(J=6-5) Emission in the z=3.91 Quasar Host of APM08279+5255
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We report the detection of surprisingly strong HCN, HNC, and HCO+(J=6-5) emission in the host galaxy of the z=3.91 quasar APM08279+5255 through observations with CARMA. HCN, HNC, and HCO+ are typicall...

2010/3/8
We analyse Spitzer MIPS 24micron observations, and SDSS (DR7) optical broadband photometry and spectra, to investigate the star formation (SF) properties of galaxies residing in the Coma supercluster ...
