Oxygen and iron in interstellar dust: an X-ray investigation

I. Psaradaki, E. Costantini, D. Rogantini +9

Understanding the chemistry of the interstellar medium (ISM) is fundamental for the comprehension of the Galactic and stellar evolution. X-rays provide an excellent way to study th…

Silicon X-ray absorption in the Galactic ISM: the gaseous component

E. Gatuzz, T. W. Gorczyca, M. F. Hasoglu +3

We present a detailed analysis of the gaseous component of the Si K edge using high-resolution Chandra spectra of low-mass X-ray binaries. We fit the spectra with amodified version…

The Chandra High Resolution X-ray Spectrum of Quiescent Emission from Sgr A*

L. Corrales, F. K. Baganoff, Q. D. Wang +7

In quiescence, Sgr A* is surprisingly dim, shining 100,000 times less than expected for its environment. This problem has motivated a host of theoretical models to explain radiativ…

Chandra Spectral and Timing Analysis of Sgr A*'s Brightest X-ray Flares

Daryl Haggard, Melania Nynka, Brayden Mon +17

We analyze the two brightest Chandra X-ray flares detected from Sagittarius A*, with peak luminosities more than 600 x and 245 x greater than the quiescent X-ray emission. The brig…

Astro2020 Science White Paper: Probing the Structure of Interstellar Dust from Micron to Kpc Scales with X-ray Imaging

Lynne Valencic, Lia Corrales, Sebastian Heinz +8

The X-ray regime is a largely underused resource for constraining interstellar dust grain models and improving our understanding of the physical processes that dictate how grains e…

High-Energy Photon and Particle Effects onExoplanet Atmospheres and Habitability

Jeremy J. Drake, Julián D. Alvarado-Gómez, Vladimir Airapetian +41

It is now recognized that energetic stellar photon and particle radiation evaporates and erodes planetary atmospheres and controls upper atmospheric chemistry. Key exoplanet host s…

The X-ray variable sky as seen by MAXI: the future of dust echo tomography with bright Galactic X-ray bursts

Lia Corrales, Brianna S. Mills, Sebastian Heinz +1

Bright, short duration X-ray flares from accreting compact objects produce thin, dust scattering rings that enable dust echo tomography: high precision distance measurements and ma…

The Advanced X-ray Imaging Satellite

Richard F. Mushotzky, James Aird, Amy J. Barger +41

Much of the baryonic matter in the Universe, including the most active and luminous sources, are best studied in the X-ray band. Key advances in X-ray optics and detectors have pav…

The Chandra Dust Scattering Halo of Galactic Center transient Swift J174540.7-290015

L. Corrales, B. Mon, D. Haggard +4

We report the detection of a dust scattering halo around a recently discovered X-ray transient, Swift J174540.7-290015, which in early February of 2016 underwent one of the brighte…

The Impact of Accurate Extinction Measurements for X-ray Spectral Models

Randall K. Smith, Lynne A. Valencic, Lia Corrales

Interstellar extinction includes both absorption and scattering of photons from interstellar gas and dust grains, and it has the effect of altering a source's spectrum and its tota…

The dust scattering component of X-ray extinction: Effects on continuum fitting and high-resolution absorption edge structure

L. Corrales, J. Garcia, J. Wilms +1

Small angle scattering by dust grains causes a significant contribution to the total interstellar extinction for any X-ray instrument with sub-arcminute resolution (Chandra, Swift,…

X-ray Scattering Echoes and Ghost Halos from the Intergalactic Medium: Relation to the nature of AGN variability

Lia Corrales

X-ray bright quasars might be used to trace dust in the circumgalactic and intergalactic medium through the phenomenon of X-ray scattering, which is observed around Galactic object…

Hydrodynamical Response of a Circumbinary Gas Disk to Black Hole Recoil and Mass Loss

Lia R. Corrales, Zoltán Haiman, Andrew MacFadyen

Finding electromagnetic (EM) counterparts of future gravitational wave (GW) sources would bring rich scientific benefits. A promising possibility, in the case of the coalescence of…
