Dust grain chemistry in the diffuse ISM towards the black hole transient GX 339-4
I. Psaradaki, L. Corrales, E. Costantini +10
We present results on X-ray absorption and the dust grain chemistry in the diffuse interstellar medium (ISM), based on a new Cycle 25 Chandra High Energy Transmission Grating Spect…
The Feasibility of Using Fe XXIII Metastable Transitions as a Density Diagnostic for LMXB Disk Winds
D. L. Moutard, L. R. Corrales, R. Tomaru +6
Low mass X-ray binaries (LMXBs) occasionally show signs of outflowing material from the accretion disk. Studying these outflows can inform the understanding of the geometry of the…
Complex Ionization and Velocity Structures in GX 340+0 X-ray Binary Revealed by XRISM
Priyanka Chakraborty, Randall Smith, Lia Corrales +11
We present the first high-resolution XRISM spectrum of the neutron star low-mass X-ray binary GX 340+0, revealing unprecedented detail in its emission and absorption features. The…
The Structure of the Relativistic Fe Line in GX 340+0 as Viewed with XRISM/Resolve, NICER, and NuSTAR
R. M. Ludlam, R. Ballhausen, P. Chakraborty +13
We present a 152 ks XRISM/Resolve observation of the persistently accreting Z source GX 340+0. Simultaneous observations also occurred with NuSTAR and NICER for 22.47 ks and 2.7 ks…
XRISM insights for interstellar Sulfur
Lia Corrales, Elisa Costantini, Sascha Zeegers +15
The X-ray Imaging Spectroscopy Mission (XRISM) provides the best spectral resolution with which to study Sulfur (S) K-shell photoabsorption features from the interstellar medium (I…
The XRISM/Resolve view of the Fe K region of Cyg X-3
XRISM Collaboration
The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes th…
