Interstellar absorption and dust scattering
Elisa Costantini, Lia Corrales
The study of the interstellar medium (ISM) in the X-rays has entered a golden age with the advent of the X-ray observatories XMM-Newton and Chandra. High-energy resolution allowed…
Astro2020: How does dust escape from galaxies?
Edmund Hodges-Kluck, Lía Corrales, Sylvain Veilleux +3
Whenever gas is blown out of a galaxy, chances are that it contains some cosmic dust. This dust is an important part of the metals budget for the circumgalactic and intergalactic m…
Si K Edge Structure and Variability in Galactic X-Ray Binaries
Norbert S. Schulz, Lia Corrales, Claude R. Canizares
We survey the Si K edge structure in various absorbed Galactic low-mass X-ray binaries (LMXBs) to study states of silicon in the inter- and circum-stellar medium. The bulk of these…
The Dust Scattering Halo of Cygnus X-3
Lia Corrales, Frits Paerels
Dust grains scatter X-ray light through small angles, producing a diffuse halo image around bright X-ray point sources situated behind a large amount of interstellar material. We p…
