A GREEN BANK TELESCOPE SURVEY FOR H I 21 cm ABSORPTION IN THE DISKS AND HALOS OF LOW-REDSHIFT GALAXIES
21 cm absorption survey Green Bank Telescope
2014/12/20
We present an H I 21 cm absorption survey with the Green Bank Telescope (GBT) of galaxy-quasar pairs selected by combining galaxy data from the Sloan Digital Sky Survey (SDSS) and radio sources from t...
The clustering of galaxies around damped absorbers
Clustering damping Galaxy Wide-angle image The redshift slices. Bayesian metering redshift technology
2014/12/9
We measured the clustering of galaxies around damped absorbers, all at a redshift of approximately three. For this purpose, we used wide-field images that covered a total area of one square degree. We...
Measures of Star Formation Rates within Galaxies: the Impact of Diffuse Stellar Populations
galaxies:ISM ISM:structure infrared:galaxies infrared:ISM H{\sc ii} regions
2014/12/9
Thanks to the {\it Spitzer Space Telescope}, the infrared (IR) emission have been better studied in the past decades, as well as its relations to star formation rates (SFR) and the calibrations of IR ...
Cosmological implications from the full shape of the large-scale power spectrum of the SDSS DR7 luminous red galaxies
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
2011/10/12
We obtain cosmological constraints from a measurement of the spherically averaged power spectrum (PS) of the distribution of about 90000 luminous red galaxies (LRGs) across 7646 deg2 in the Northern G...
The Ks-band Tully–Fisher Relation – A Determination of the Hubble Parameter from 218 ScI Galaxies and 16 Galaxy Clusters
Distance scale—galaxies distances and redshifts
2010/9/15
The value of Hubble parameter (H0) is determined using the morphologically type dependent Ks-band Tully–Fisher Relation (K-TFR).The slope and zero point are determined using 36 calibrator galaxies wit...
