Context 

In the last two decades, the X-ray view of our Universe has been transformed by the two large imaging telescopes Chandra X-ray Observatory, XMM-Newton or for surveys with eROSITA. In addition, microcalorimeter-equipped telescopes are now a reality with XRISM and the upcoming NewAthena satellite.

With 25 years of  X-ray archives, all-sky surveys and unprecedented high spectral resolution observations from microcalorimeters, X-ray data have never been more scientifically rich, but also more complex to analyze. Despite this huge improvement in data quality and quantity, the development of the analysis methods has stalled in the last decades and current methods cannot fully exploit the wealth of information encoded in these rich datasets.

Goals

This workshop aims at gathering experts across the high-energy astrophysics community to define a new generation of analysis tools using advanced algorithms to maximize the scientific return of our complex X-ray datasets.  The goals of this meeting is to present the limitations of existing tools and have an overview of the ongoing efforts and methods available towards a new generation of X-ray analysis tools.

Why organize it now?

The timing is ideal for organizing this type of workshop:

• The adoption of NewAthena (scheduled for 2027) is approaching, and a A&A special issue on this future mission is planned for late 2026. The tools presented during this workshop will be valuable assets for these upcoming articles and will showcase the full potential and feasibility of this telescope.
  
• XRISM PV data will become public in autumn 2025. European teams who had access to these data will share their experiences, challenges, and insights from their analyses.

 

Format 

This workshop does not have a typical conference format. We plan to have:

• A few general overview presentations
• Tutorials led by experts on topics such as innovative fitting tools and their comparisons, observation simulation software, and methods for accelerating analyses
  
• Short presentations by participants with a particular focus on innovative methods and the challenges in their research fields, both methodological and scientific.
• Ample free time for collaboration and discussions on key challenges within the community. 

 

Where

This workshop at the Institut Pascal, located on the campus of the Université Paris-Saclay in Orsay.
