Data Analysis

The goal of this work package is to provide trans-national access (TA) to X-ray (and gamma-ray) data analysis methods including use of data tools, archives and space instruments via tutorials and mentoring by experienced scientists at the delivery institutes. The primary aim is to widen opportunities for scientists across Europe to exploit both European-funded and international X-ray astronomy facilities and X-ray data archives in order to enhance high-energy astrophysics science across Europe. The activities will be particularly designed to assist relatively inexperienced users in smaller institutes, but will be tailored to the needs of scientists with a wide range of experience. The delivery institute will provide the users with: a hands-on tutorial in the most up-to-date methods in X-ray data analysis (imaging, time series, spectroscopy); specific data analysis methods tailored to the users own research project(s); assistance with using software packages specific to European and international X-ray missions; given guidance in the exploitation of data archives located at the host institutions and elsewhere, including multi-waveband analysis; and mentoring in how to make use of the software and X-ray facilities when the user returns home, including a point of contact at the delivery institute for follow-up discussions. Thus, a visit will be part of a process to enable science for the user rather than a single end point.

All visits are fully supported for travel and subsistence expenses.

SRON Netherlands Institute for Space Research (NL)

SRON is the leading institute in Europe for the analysis of high-resolution X-ray spectra. The institute is Principal Investigator on the two grating instruments currently operational in the soft X-ray band (the ESA mission XMM-Newton and the NASA mission Chandra). For the analysis of the collected spectra, SRON developed dedicated analysis software, which allows analyzing high-resolution spectra in a self-consistent way based on atomic transition probabilities (SPEX, www.sron.nl/spex).Furthermore, SRON is leading the European contribution to the Japanese satellite XRISM. This mission, while having its own unique science capability, can also be considered as a pathfinder for the X-ray Integral Field Unit on ATHENA.
Services offered by the infrastructure:
SRON combines detailed knowledge about the instrument performance and the physical interpretation of the collected data, w.p.r.t. high spectral X-ray resolution. The SRON science is strongly linked to this expertise and includes clusters of galaxies (the physical properties of the hot gas, including the thermo-dynamical conditions), properties of matter close to AGNs and the relevant feedback, and properties of interstellar dust, which can be uniquely probed in X-rays as well. This expertise, together with the dedicated software to analyze high-resolution spectra are unique in the world. As part of this TNA, SRON will provide its facilities including expert knowledge for scientists in Europe on high-resolution data such as that provided by the forthcoming XRISM mission.
