چکیده
The Centre of our Galaxy the Central Molecular Zone (CMZ), contains 80% of all dense gas in the Galaxy, but holds only about 5% of current star formation. The CMZ is hotter, denser and more turbulent than anywhere else in the Galaxy. It is a truly unique place. It is also important as the CMZ has analogues in other galaxies that are typically used to estimate extragalactic star formation rates. Yet we do not understand the star formation in the CMZ. I will describe the CMZ and present recent models to explain the unusual star formation. I will also introduce a way to make a 3 dimensional model of the CMZ with the hope that this can be used to help us understand how star formation proceeds under extreme circumstances.

NRAO/Socorro Colloq. Abstract
Feedback from star formation is central to cosmological models of galaxy formation and evolution. Tuning the feedback prescription so that simulations reproduce the observed properties of the galaxy population has provided much insight into which galaxies might lose significant amounts of metals and gas via galactic winds. The challenge comes in testing these descriptions against empirical meas...
متن کاملNRAO/Socorro Colloq. Abstract
Mergers of galaxy clusters -some of the most energetic events in the Universe -produce disturbances in hot intracluster medium, such as shocks and cold fronts, that can be used as tools to study the physics of galaxy clusters. X-ray observations of shock fronts provide information on the shock Mach number and velocity, and for wellobserved shocks, constrain the microphysical properties of the i...
متن کاملNRAO/Socorro Colloq. Abstract
The giant molecular cloud G0.253+0.016 or "The Brick" is a massive (M~10^5 solar masses) cloud in the Galactic center. Its apparent lack of star formation given its large mass makes it unique in our Galaxy, and as such it has been the subject of more than a dozen papers in just the last 3 years. The properties of this cloud are being used to understand everything from the quiescent initial stag...

متن کاملPulsars identified from the NRAO VLA Sky Survey
Abstract. We identified 97 strong pulsars from the NRAO VLA Sky Survey (NVSS) at 1.4 GHz north of Dec(J2000) > −40◦. The total flux density, linear polarization intensity and polarization angle (PA) of all pulsars are extracted from the NVSS catalog. The well-calibrated PA measurement of 5 pulsars can be used for absolute PA calibrations in other observations. Comparing the source positions wit...
