Science of High Resolution X-ray Imaging
H. L. Marshall, K. Weaver, M. Schattenburg +34
This report summarizes potential studies of the Hi-ReX Science Analysis Group for an Ultra-High Angular Resolution X-ray Observatory. Many potential science cases are presented, sp…
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…
Taming the Tarantula: How Stellar Wind Feedback Shapes Gas and Dust in 30 Doradus
Jennifer A. Rodriguez, Laura A. Lopez, Lachlan Lancaster +5
Observations of massive star-forming regions show that classical stellar wind models over-predict the luminosity of the X-ray emitting gas, indicating a significant fraction of win…
Proper Motion of the Neutron Star in the Supernova Remnant G18.9-1.1
Tyler Holland-Ashford, Brian Williams, Patrick Slane +1
In this paper, we present the first direct measurement of the proper motion of the neutron star (NS) in the supernova remnant (SNR) G18.9-1.1 using a 15-year Chandra baseline. Afte…
Estimating Global Ejecta Mass Ratios in Tycho's SNR
Tyler Holland-Ashford, Patrick Slane, Brian Williams
In this work, as a follow-up to our similar analysis of Kepler's supernova remnant (SNR), we estimate total mass ratios of various ejecta elements in Tycho's SNR using Suzaku X-ray…
Updated Proper Motion of the Neutron Star in the Supernova Remnant Cassiopeia A
Tyler Holland-Ashford, Patrick Slane, Xi Long
In this paper, we present updated estimates of the velocity of the neutron star (NS) in the supernova remnant (SNR) Cassiopeia A using over two decades of Chandra observations. We…
