Sherpa: a Mission-Independent Data Analysis Application
read the original abstract
The ever-increasing quality and complexity of astronomical data underscores the need for new and powerful data analysis applications. This need has led to the development of Sherpa, a modeling and fitting program in the CIAO software package that enables the analysis of multi-dimensional, multi-wavelength data. In this paper, we present an overview of Sherpa's features, which include: support for a wide variety of input and output data formats, including the new Model Descriptor List (MDL) format; a model language which permits the construction of arbitrarily complex model expressions, including ones representing instrument characteristics; a wide variety of fit statistics and methods of optimization, model comparison, and parameter estimation; multi-dimensional visualization, provided by ChIPS; and new interactive analysis capabilities provided by embedding the S-Lang interpreted scripting language. We conclude by showing example Sherpa analysis sessions.

Fe K$\alpha$ line from the Broad Line Region of PDS456 with XRISM/Resolve
XRISM/Resolve reveals a narrow, blueshifted neutral Fe Kα line (EW ≈ 9 eV, v_out ≈ 2700 km/s) in quasar PDS 456, likely from the outer Broad Line Region at the high-luminosity end of the X-ray Baldwin effect.

Origin of the Sloshing Spiral in the Abell 2107 Galaxy Cluster
A previously unknown sloshing spiral with three cold fronts is discovered in the ICM of the apparently relaxed cluster Abell 2107, pointing to a past off-axis merger with a possibly dark perturber.
