24 Feb 2004 | | Subject: | astro-ph | | Affiliation: | NRAO), F. Bertoldi (MPIfR), F. Walter (NRAO), K.M. Menten (MPIfR), A. Beelen, P. Cox (UParis-Sud), A. Omont (IAP | | Abstract: | We review cm and mm observations of thermal molecular line emission from high redshift QSOs. These observations reveal the massive gas reservoirs (10^{10} to 10^{11} M_sun) required to fuel star formation at high rates. We discuss evidence for active star formation in QSO host galaxies, and we show that these high redshift, FIR-luminous QSOs follow the non-linear trend of increasing L_{FIR}/L’(CO) with increasing L_{FIR}. We conclude with a brief discussion of the recent CO detection of the most distant QSO at z=6.42, and its implications for cosmic reionization. | | Source: | arXiv, astro-ph/0402573 | | Services: | Forum | Review | PDF | Favorites | |
