A first view of interstellar Fe-bearing dust grains with XRISM
I. Psaradaki, L. Corrales, E. Costantini +8
Understanding the reservoirs of iron (Fe) in our Galaxy is crucial for probing the mechanisms that drive dust grain growth in the interstellar medium (ISM). High-resolution X-ray a…
Investigation of Calcium Dust in the Interstellar Medium
Ya-Yu Chu, Sascha Zeegers, Hsien Shang +7
Calcium is a highly depleted element in the interstellar medium (ISM), however its composition in the solid phase remains elusive. The detection of Ca-bearing dust has been limited…
Investigating interstellar dust along the line of sight of GX 13+1 using different dust size distributions
B. Vaia, S. T. Zeegers, I. Abril-Cabezas +1
Context. High-resolution X-ray spectroscopy offers a powerful tool to investigate the physical and chemical properties of dust grains, especially through the analysis of absorption…
Silicon, sulfur and iron in the interstellar medium: a high-resolution X-ray spectral study of GX 340+0
Daniele Rogantini, Claude Canizares, Elisa Costantini +5
High-resolution X-ray spectroscopy provides a powerful probe of the interstellar medium (ISM), giving direct access to the composition and physical state of dust grains and atomic…
A Tale of Two Sightlines: Comparison of Hydrocarbon Dust Absorption Bands toward Cygnus OB2-12 and the Galactic Center
Yvonne J. Pendleton, T. R. Geballe, Laurie E. U. Chu +14
Infrared spectra of hydrocarbon dust absorption bands toward the bright hypergiant Cygnus OB2-12 are compared to published spectra of the Quintuplet Cluster, a sightline to the Gal…
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…
Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI
S. T. Zeegers, Jonathan P. Marshall, Karl D. Gordon +33
The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reac…
A first taste of MEAD (Measuring Extinction and Abundances of Dust) -- I. Diffuse Milky Way interstellar dust extinction features in JWST infrared spectra
Marjorie Decleir, Karl D. Gordon, Karl A. Misselt +3
We present the initial results of MEAD (Measuring Extinction and Abundances of Dust), with a focus on the dust extinction features observed in our JWST near- and mid-infrared spect…
Interstellar dust along the line of sight of GX 3+1
D. Rogantini, E. Costantini, S. T. Zeegers +6
Studying absorption and scattering of X-ray radiation by interstellar dust grains allows us to access the physical and chemical properties of cosmic grains even in the densest regi…
X-ray extinction from interstellar dust: Prospects of observing carbon, sulfur and other trace elements
E. Costantini, S. T. Zeegers, D. Rogantini +3
We present a study on the prospects of observing carbon, sulfur, and other lower abundance elements (namely Al, Ca, Ti and Ni) present in the interstellar medium using future X-ray…
Dust absorption and scattering in the silicon K-edge
S. T. Zeegers, E. Costantini, D. Rogantini +5
The composition and properties of interstellar silicate dust are not well understood. In X-rays, interstellar dust can be studied in detail by making use of the fine structure feat…
Absorption and scattering by interstellar dust in the silicon K-edge of GX 5-1
S. T. Zeegers, E. Costantini, C. P. de Vries +6
We study the absorption and scattering of X-ray radiation by interstellar dust particles, which allows us to access the physical and chemical properties of dust. The interstellar d…
