CO(1-0) in z gtrsim 4 Quasar Host Galaxies: No Evidence for Extended Molecular Gas Reservoirs
formation high-redshift
2014/12/24
We present 12CO(J = 1 → 0) observations of the high-redshift quasi-stellar objects (QSOs) BR 1202-0725 (z = 4.69), PSS J2322+1944 (z = 4.12), and APM 08279+5255 (z = 3.91) using the NRAO Green Bank Te...

Far-infrared Molecular CO Emission Host Galaxies Faint Quasars
2011/10/21
We present new millimeter and radio observations of nine z~6 quasars discovered in deep optical and near-infrared surveys. We observed the 250 GHz continuum in eight of the nine objects and detected t...
Using HST observations of 147 host galaxies of low-mass black holes (BHs), we systematically study the structures and scaling relations of these active galaxies. Our sample is selected to have central...
Preliminary Results on VLT K-band Imaging Observations of GRB Host Galaxies

We have obtained K-band imaging observations of Gamma-
Ray Burst (GRB) host galaxies with the near-infrared spectro-imager
ISAAC installed on the Very Large Telescope at Paranal (Chile). The
