Deep XMM-Newton Observations Reveal the Origin of Recombining Plasma in the Supernova Remnant W44

Hiromichi Okon, Takaaki Tanaka, Hiroyuki Uchida +8

Recent X-ray studies revealed over-ionized recombining plasmas (RPs) in a dozen mixed-morphology (MM) supernova remnants (SNRs). However, the physical process of the over-ionizatio…
