High Spectral Resolution X-ray Observations of the Evolved Supermassive Stellar Binary System Carinae - Iron K Band Profile Revealed with XRISM
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +138
The supermassive binary system, Carinae, is experiencing enormous wind-driven mass loss at a rate unparalleled in the rest of the Galaxy. Their wind-wind collision (WWC) contin…
XRISM Observation of the Supernova Remnant N103B: Velocity Structure and Thermal Properties
Tyler Holland-Ashford, Brian J. Williams
We present the first analysis of the X-ray Imaging and Spectroscopy Mission (XRISM) observation of the supernova remnant (SNR) N103B. We fit the X-ray spectrum taken with the Resol…
Comparing the three-dimensional morphological asymmetries in the ejecta of Kepler and Tycho in X-rays
Adrien Picquenot, Tyler Holland-Ashford, Brian J. Williams
Recent simulations have shown that asymmetries in the ejecta distribution of supernova remnants (SNRs) may be a reflection of asymmetries left over from the initial supernova explo…
Mapping thermal emission in the synchrotron-dominated SNRs 330.2+1.0, 3C58, and RX J1713.7-3946
Adrien Picquenot, Brian J. Williams, Fabio Acero +1
Since the discovery of synchrotron X-ray emission from the shell of the supernova remnant (SNR) SN 1006, multiple observations from Chandra and XMM-Newton have shown that many youn…
