Mapping the spectral index of Cas A: evidence for flattening from radio to infrared
V. Domček, J. Vink, J. V. Hernández Santisteban +2
Synchrotron radiation from supernova remnants are caused by electrons accelerated through diffusive shock acceleration (DSA). The standard DSA theory predicts an electron spectral…
The distribution of radioactive Ti in Cassiopeia A
Brian W. Grefenstette, Chris L. Fryer, Fiona A. Harrison +28
The distribution of elements produced in the inner-most layers of a supernova explosion is a key diagnostic for studying the collapse of massive stars. Here we present the results…
The NuSTAR Extragalactic Surveys: Initial Results and Catalog from the Extended Chandra Deep Field South
J. R. Mullaney, A. Del-Moro, J. Aird +33
We present initial results and the source catalog from the NuSTAR survey of the Extended Chandra Deep Field South (hereafter, ECDFS) - currently the deepest contiguous component of…
The NuSTAR Extragalactic Surveys: First Direct Measurements of the >10 keV X-Ray Luminosity Function for Active Galactic Nuclei at z>0.1
J. Aird, D. M. Alexander, D. R. Ballantyne +34
We present the first direct measurements of the rest-frame 10-40 keV X-ray luminosity function (XLF) of Active Galactic Nuclei (AGNs) based on a sample of 94 sources at 0.1 < z <3,…
Locating the most energetic electrons in Cassiopeia A
Brian W. Grefenstette, Stephen P. Reynolds, Fiona A. Harrison +17
We present deep (2.4 Ms) observations of the Cassiopeia A supernova remnant with {\it NuSTAR}, which operates in the 3--79 keV bandpass and is the first instrument capable of sp…
On the Expansion Rate, Age, and Distance of the Supernova Remnant G266.2-1.2 (Vela Jr.)
G. E. Allen, K. Chow, T. DeLaney +4
An analysis of Chandra ACIS data for two relatively bright and narrow portions of the northwestern rim of G266.2-1.2 (a.k.a. RX J0852.0-4622 or Vela Jr.) reveal evidence of a radia…
