SN1006
SN1006 offers an ideal laboratory to probe into the physics of the collisionless processes, because of its high shock velocity and the low ambient density. Here we propose Resolve observations of the two SNR rims, SE and NW, both dominated by thermal X-ray emission from the extremely low-ionized plasma, but with different shock velocities. The minimal goal is to accurately measure the ion (neon) and electron temperatures to constrain the efficiency of the collisionless electron heating and its velocity dependence. The ideal goal is to measure the temperatures of various heavy elements (N, O, Ne, Mg, Si, and Fe) to investigate the relationship between their temperatures and atomic mass. A short observation of the SNR Center is also proposed to demonstrate the wide FoV of the Xtend.
