New Evidence for Efficient Collisionless Heating of Electrons at the Reverse Shock of a Young Supernova Remnant
Hiroya Yamaguchi, Kristoffer A. Eriksen, Carles Badenes +7
Although collisionless shocks are ubiquitous in astrophysics, certain key aspects of them are not well understood. In particular, the process known as collisionless electron heatin…
A Chandra View Of Nonthermal Emission In The Northwestern Region Of Supernova Remnant RCW 86: Particle Acceleration And Magnetic Fields
Daniel Castro, Laura A. Lopez, Patrick O. Slane +3
The shocks of supernova remnants (SNRs) are believed to accelerate particles to cosmic ray (CR) energies. The amplification of the magnetic field due to CRs propagating in the shoc…
Unraveling the Origin of Overionized Plasma in the Galactic Supernova Remnant W49B
Laura A. Lopez, Sarah Pearson, Enrico Ramirez-Ruiz +4
Recent observations have shown several supernova remnants (SNRs) have overionized plasmas, those where ions are stripped of more electrons than they would be if in equilibrium with…
Asymmetric Ejecta Distribution in SN 1006
Hiroyuki Uchida, Hiroya Yamaguchi, Katsuji Koyama
We present the results from deep X-ray observations (~400 ks in total) of SN 1006 by the X-ray astronomy satellite Suzaku. The thermal spectrum from the entire supernova remnant (S…
