3D Kinematic Reconstruction of the Crab Nebula That Includes the Northern Ejecta `Jet'
Ziwei Ding, Dan Milisavljevic, Thomas Martin +4
We present new detailed three-dimensional kinematic reconstructions of the Crab Nebula created from hyperspectral cubes obtained with the SITELLE instrument mounted on the Canada--…
Dialogue Concerning the Two Shock Codes
Yifei Jin, John Raymond
In this paper, we summarize the shock physics and the treatment of radiative transfer in two well-established shock codes -- the MAPPINGS code (Dopita1976,Binette1985,Sutherland199…
Spectroscopy of Supernova Remnants and Candidates in M31
Nelson Caldwell, John C. Raymond, Knox S. Long +1
With a star formation rate of order 0.4 M yr, M31 should have significant population of supernova remnants (SNRs), and, in fact, 156 SNR and SNR candidates have bee…
Differentiating the acceleration mechanisms in the slow and Alfvénic slow solar wind
Yeimy J. Rivera, Samuel T. Badman, J. L. Verniero +18
In the corona, plasma is accelerated to hundreds of kilometers per second, and heated to temperatures hundreds of times hotter than the Sun's surface, before it escapes to form the…
The Distance to the S147 Supernova Remnant
C. S. Kochanek, J. C. Raymond, N. Caldwell
In the absence of a parallax distance to a pulsar or a surviving binary in a supernova remnant (SNR), distances to Galactic SNRs are generally very uncertain. However, by combining…
Solar Energetic Particle Charge States and Abundances with Nonthermal Electrons
Jin-Yi Lee, Stephen Kahler, John C. Raymond +1
An important aspect of solar energetic particle (SEP) events is their source populations. Elemental abundance enhancements of impulsive SEP events, originating in presumed coronal…
Investigating the impact of atomic data uncertainties on measured physical parameters of the Perseus galaxy cluster
Priyanka Chakraborty, Rachel Hemmer, Adam R. Foster +4
Accurate atomic data and plasma models are essential for interpreting the upcoming high-quality spectra from missions like XRISM and Athena. Estimating physical quantities, like te…
Front-row seat of the recent R Aqr periastron passage: X-ray multi-epoch spectral and spatial analysis
A. Sacchi, M. Karovska, J. Raymond +7
We report on the X-ray spectral and spatial evolution of the Symbiotic star R Aqr. Through a multi-epoch observational campaign performed with Chandra between 2017 and 2022, we stu…
New resonance scattering model in AtomDB: application to line suppression in galaxy clusters and elliptical galaxies
Priyanka Chakraborty, Adam Foster, Randall Smith +2
In this paper, we present a simple, one-step, self-consistent, and fast resonance scattering model rsapec based on the AtomDB database. This model can be used as an alternative to…
Disk-Wind Connection During the Heartbeats of GRS 1915+105
Abderahmen Zoghbi, J. M. Miller, A. L. King +14
Disk and wind signatures are seen in the soft state of Galactic black holes, while the jet is seen in the hard state. Here we study the disk-wind connection in the class of var…
An Ultra-Fast X-ray Disk Wind in the Neutron Star Binary GX 340+0
J. M. Miller, J. Raymond, E. Cackett +2
We present a spectral analysis of a brief Chandra/HETG observation of the neutron star low-mass X-ray binary GX~340+0. The high-resolution spectrum reveals evidence of ionized abso…
Powerful, Rotating Disk Winds from Stellar-mass Black Holes
J. M. Miller, A. C. Fabian, J. Kaastra +5
We present an analysis of ionized X-ray disk winds observed in the Fe K band of four stellar-mass black holes observed with Chandra, including 4U 1630-47, GRO J1655-40, H 1743-322,…
Chandra Spectroscopy of MAXI J1305-704: Detection of an Infalling Black Hole Disk Wind?
J. M. Miller, J. Raymond, T. R. Kallman +9
We report on a Chandra/HETG X-ray spectrum of the black hole candidate MAXI J1305-704. A rich absorption complex is detected in the Fe L band, including density-sensitive lines fro…
On the properties of thermal disk winds in X-ray transient sources: a case study of GRO J1655-40
S. Luketic, D. Proga, T. R. Kallman +2
We present the results of hydrodynamical simulations of the disk photosphere irradiated by strong X-rays produced in the inner most part of the disk. As expected, the irradiation h…
