Keck Spectroscopy of Faint 3 Lyman Break Galaxies:- Evidence for a Declining Fraction of Emission Line Sources In the Redshift Range 6
Keck Spectroscopy Declining Fraction Emission Line Sources
2011/9/29
Using deep Keck spectroscopy of Lyman break galaxies selected from infrared imaging data taken with WFC3/IR onboard the Hubble Space Telescope, we present new evidence for a reversal in the redshift-d...

Hidden blazars and emission line variability of high redshift quasars。
With the launch of the Chandra X-ray Observatory, high resolution X-rayspectroscopy of cosmic sources has begun. Early, deep observations of three stellarcoronal sources桟apella, Pro cyon, and HR 1099梐...
