Dense Molecular Gas Excitation at High Redshift: Detection of HCO+(J=4-3) Emission in the Cloverleaf Quasar
galaxies active — galaxies starburst — galaxies formation — galaxies
2010/11/10
We report the detection of HCO+(J=4→3) emission in the Cloverleaf Quasar at z=2.56, using
the IRAM Plateau de Bure Interferometer. HCO+ emission is a star formation indicator similar
to HCN, tracing...
The HETDEX Pilot Survey III: The Low Metallicities of High-Redshift Lyman Alpha Galaxies
galaxies evolution
2010/11/9
We present the results of Keck/NIRSPEC spectroscopic observations of three Ly emitting galaxies (LAEs)at z∼ 2.3 discoveredwith the HETDEX pilot survey. We detectH , [O III], and H emission fro...
GRB 050502B optical afterglow: a jet break at high redshift
Gamma rays bursts observations individual GRB 050502B
2010/11/9
Aims. GRB050502B is well known for the very bright flare displayed in its X-ray light curve. Despite extensive studies, however, the optical light curve has never been discussed and its redshift is un...
