"First results from the hard X-ray sensitive astronomical satellite NuSTAR "

Greg Madejski (Stanford University)

[Seminar] NuSTAR is a satellite-based astronomical observatory, sensitive in the hard X-ray band, over the range of 3 - 80 keV. It consisting of mirrors capable of focusing hard X-rays onto the pixelated CdZnTe detector. The observatory was launched in July 2012, and continues to operate flawlessly. This presentation will give a broad overview of the scientific results obtained with NuSTAR. Those will cover the new insights gleaned from sensitive observations of hard X-ray sources in our Galaxy, such as supernova remnants and the Galactic Center, and extragalactic sources such as active galaxies, and clusters of galaxies.
