Recent X-ray studies of starburst galaxies have found that charge exchange (CX) commonly occurs between outflowing hot plasma and cold gas, possibly from swept-up clouds. However, the total CX flux and the regions where CX occurs have been poorly und

The nature of Type Ia supernovae remains controversial. The youngest remnants of Ia supernovae hold clues to the explosion and to the immediate surroundings. We present a third epoch of Chandra observations of the ∼600 yr old Type Ia remnant 0519

Recent simulations have shown that asymmetries in the ejecta distribution of supernova remnants (SNR) can still reflect asymmetries from the initial supernova explosion. Thus, their study provides a great means to test and constrain model predictions

In high-energy astronomy, spectro-imaging instruments such as X-ray detectors allow investigation of the spatial and spectral properties of extended sources including galaxy clusters, galaxies, diffuse interstellar medium, supernova remnants, and pul

In this article, we investigate how the prior knowledge based on examples of physical spectra can be exploited in sparse Blind Source Separation (sBSS), based on the projection onto the barycentric span of these examples. For that purpose, we investi

Blind source separation (BSS) aims at recovering signals from linear mixtures. This problem has been extensively studied when the noise is additive and Gaussian. This is however not the case when the measurements follow Poisson or shot noise statisti
