Diffuse HI Disks in Isolated Galaxies
David E. Hogg, Morton S. Roberts, Martha P. Haynes +1
In order to investigate the contribution of diffuse components to their total HI emission, we have obtained high precision HI line flux densities with the 100m Green Bank Telescope…
CO(1-0) in z >/~ 4 Quasar Host Galaxies: No Evidence for Extended Molecular Gas Reservoirs
Dominik A. Riechers, Fabian Walter, Christopher L. Carilli +11
We present CO(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 B…
Starburst Driven Thermal and Non-thermal Structures in the Galactic Center Region
F. Yusef-Zadeh, W. Cotton, J. Hewitt +3
We briefly review the prominent thermal and nonthermal sources near the Galactic center. These sources include the young stellar clusters, the Sgr B complex as well as the large-sc…
High Redshift HCN Emission: Dense Star-Forming Molecular Gas in IRAS F10214+4724
P. A. Vanden Bout, P. M. Solomon, R. J. Maddalena
Hydrogen cyanide emission in the J=1-0 transition has been detected at redshift z=2.2858 in IRAS F10214+4724 using the Green Bank Telescope . This is the second detection of HCN em…
On the Continuing Formation of the Andromeda Galaxy: Detection of HI Clouds in the M31 Halo
David A. Thilker, Robert Braun, Rene A. M. Walterbos +4
Green Bank Telescope (GBT) 21cm observations have revealed a faint, yet extensive HI cloud population surrounding the Andromeda Galaxy (M31). The newfound objects are likely analog…
