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…
Young Stellar Clusters, WR-type Phenomenon and the Origin of the Galactic Center Nonthermal Radio Filaments
F. Yusef-Zadeh
Recent observations of the Arches cluster located within a projected distance of 30 pc from the dynamical center of the Galaxy have shown the presence of diffuse and discrete X-ray…
Discovery of an OH(1720 MHz) Maser in the LMC
D. A. Roberts, F. Yusef-Zadeh
We report the first study of OH(1720 MHz) masers in the LMC in order to probe regions where supernova remnants interact with adjacent molecular clouds. Using the ATCA, we observed…
A Jet Model of the Galactic Center Nonthermal Radio Filaments
F. Yusef-Zadeh, A. Königl
Protostellar sources in star forming regions are responsible for driving jets with flow velocities ranging between 300 and 400 km s. This class of jets consists of highly co…
The Nature of 3EG J1746-2851 in the Nucleus of the Galaxy
F. Yusef-Zadeh
There are a number of candidate sources that are considered to be responsible for the origin of the EGRET source 3EG J1746--2851 (Hartman et al. 1999). The lack of clear identifica…
Supernova OH (1720 MHz) Masers in Sgr A East, W28 and G359.1-0.5
F. Yusef-Zadeh, D. A. Roberts, G. Bower +1
A new class of OH (1720 MHz) masers unaccompanied by main-line transitions have recently been discovered (Frail, Goss and Slysh 1994). These masers lie at the interface between sup…
