The Heating of Thermal Electrons in Fast Collisionless Shocks: The Integral Role of Cosmic Rays
Cara E. Rakowski, J. Martin Laming, Parviz Ghavamian
Understanding the heating of electrons to quasi-thermal energies at collisionless shocks has broad implications for plasma astrophysics. It directly impacts the interpretation of X…
A Physical Relationship Between Electron-Proton Temperature Equilibration and Mach Number in Fast Collisionless Shocks
Parviz Ghavamian, J. Martin Laming, Cara E. Rakowski
The analysis of Balmer-dominated optical spectra from non-radiative (adiabatic) SNRs has shown that the ratio of the electron to proton temperature temperature at the blast wave is…
[Ne V] Imaging of N49 in the Large Magellanic Cloud
Cara E. Rakowski, John C. Raymond, Andrew H. Szentgyorgyi
We present sub-arcsecond imaging in [Ne V] of N49, the brightest optical SNR in the LMC. Between the "cool" optical and "hot" X-ray regimes, [Ne V] emission indicates intermediate…
Extraordinarily Hot X-ray Emission from the 09 Emission Line Star HD 119682
C. E. Rakowski, N. S. Schulz, S. J. Wolk +1
We present new optical and X-ray observations to show that the X-ray source 1 WGA J1346.5--6255 previously associated with the SNR G309.2--0.6 can be unequivocally identified with…
The Chandra View of the Supernova Remnant 0506-68.0 in the Large Magellanic Cloud
John P. Hughes, Marc Rafelski, Jessica S. Warren +4
A new Chandra observation of SNR 0506-68.0 (also called N23) reveals a complex, highly structured morphology in the low energy X-ray band and an isolated compact central object in…
Can Ejecta-Dominated Supernova Remnants be Typed from their X-ray Spectra? The Case of G337.2-0.7
Cara E. Rakowski, Carles Badenes, B. M. Gaensler +3
In this paper we use recent X-ray and radio observations of the ejecta-rich Galactic supernova remnant (SNR) G337.2-0.7 to determine properties of the supernova (SN) explosion that…
