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…

Ionization age of iron ejecta in the Galactic Type Ia supernova remnant G306.3-0.9
Makoto Sawada, Katsuhiro Tachibana, Hiroyuki Uchida +5
We present a 190 ks observation of the Galactic supernova remnant (SNR) G306.3-0.9 with Suzaku. To study ejecta properties of this possible Type Ia SNR, the absolute energy scale a…
