A Mid-Infrared Indicator for Total Infrared Luminosity and Star Formation Rate of Local and High-Redshift Galaxies
Indicator Total Infrared Luminosity High-Redshift Galaxies
2011/10/9
We present a new method to use 24 micron observations to estimate the total infrared luminosity, LIR, and the star formation rate of star-forming galaxies across the redshift range 0 < z < 3. This is ...
Star Formation Rates and Stellar Masses of H-alpha Selected Star-Forming Galaxies at z=0.84: A Quantification of the Downsizing
Star Formation Rates Stellar Masses H-alpha Selected Star-Forming Galaxies Quantification Downsizing
2011/10/13
In this work we analyze the physical properties of a sample of 153 star forming galaxies at z~0.84, selected by their H-alpha flux with a NB filter. B-band luminosities of the objects are higher than ...
Gas density and star formation in the rarified regions of discs of normal and LSB galaxies
Gas density star formation rarified regions discs normal
2011/10/11
We calculated the radial profiles of the azimuthally averaged midplane gas volume density $\rho_g$ for 11 high surface brightness (HSB) spiral galaxies, 7 low surface brightness (LSB) galaxies and 3 S...
The WiggleZ Dark Energy Survey: High Resolution Kinematics of Luminous Star-Forming Galaxies
galaxies: high-redshift – galaxies: kinematics and dynamics – galaxies: formation – galaxies: evolution
2011/10/10
We report evidence of ordered orbital motion in luminous star-forming galaxies at z~1.3. We present integral field spectroscopy (IFS) observations, performed with the OH Suppressing InfraRed Imaging S...
X-rays and hard UV radiation From the First Galaxies: Ionization Bubbles and 21 cm Observations
stars: Population III. galaxies: high-redshift. (galaxies:) quasars: general. galaxies: star formation. cosmology: theory. (cosmology:) dark ages, reionization, rst stars
2011/10/9
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light ...
The Cold Gas Content of Bulgeless Dwarf Galaxies
galaxies: dwarf– galaxies: evolution – galaxies: formation – methods:N-body simulations
2011/10/9
We present an analysis of the neutral hydrogen (HI) properties of a fully cosmological hydrodynamical dwarf galaxy, run with varying simulation parameters. As reported by Governato et al. (2010), the ...
The impact of quasars on their galaxy neighbors is an important factor in the understanding of the galaxy evolution models. The aim of this work is to characterize the close environments of quasars at...
Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies: the case of Arp 158
Galaxies: interactions – Galaxies: star formation
2011/9/28
Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt (KS) relation as in spiral disks, presenting a higher star formation rate (SFR) for a given ...
Probing cluster formation under extreme conditions: massive star clusters in blue compact galaxies
galaxies: starburst - galaxies: star clusters: general - galaxies: irregular- galaxies:star formation
2011/9/27
The numerous and massive young star clusters in blue compact galaxies (BCGs) are used to investigate the properties of their hosts. We test whether BCGs follow claimed relations between cluster popula...
