Radio-to-Far-Infrared Spectral Energy Distribution and Photometric Redshifts for Dusty Starburst Galaxies
galaxies photometric
2014/12/26
As a logical next step in improving the radio-to-submillimeter spectral index as a redshift indicator, we have investigated a technique of using the entire radio-to-far-infrared spectral energy distri...
Toward a precise measurement of matter clustering: Ly alpha forest data at redshifts 2-4
absorption lines large scale structure of universe
2014/12/26
We measure the filling factor, correlation function, and power spectrum of transmitted flux in a large sample of Lyα forest spectra, comprised of 30 Keck HIRES spectra and 23 Keck LRIS spectra. We inf...
The morphological diversities among star-forming galaxies at high redshifts in the great observatories origins deep survey
high-redshift fundamental parameters
2014/12/24
We used the deep, multiwavelength images obtained by the Great Observatories Origins Deep Survey (GOODS) to identify ~4700 Lyman break galaxies (LBGs) at z > 2.5, and 292 starburst galaxies at z ~ 1.2...
HI Fluctuations at Large Redshifts: III – Simulating the Signal Expected at GMRT
Cosmology large scale structures radiation
2009/5/19
We simulate the distribution of neutral hydrogen (HI) at
the redshifts z D 1:3 and 3:4 using a cosmological N-body simulation
along with a prescription for assigning HI masses to the particles. The...
