Abstract

The workshop “Astrophysics of Hot Plasma in Extended X-ray Sources” was organized by the XMM-Newton Science Operations Center (XMM-Newton SOC). The XMM-Newton SOC organizes a large scientific conference every 3 years. In the years in between, the Center aims to organize scientific workshops, which are specifically aimed at hot topics of current astrophysical research where X-ray observations have a main impact on the recent developments. The 2006 workshop was focused on “Variable and Broad Iron Lines around Black Holes”; in 2007, the workshop had the title “XMM-Newton: The Next Decade” exploring scientific perspectives for the mission; in 2009, the workshop was devoted to “Supersoft X-ray Sources: New Developments”; in 2010, the participants focused on “Ultra-Luminous X-ray sources and Middle Weight Black Holes”; in 2012, the workshop concentrated on “Galaxy Clusters as Giant Cosmic Laboratories”; in 2013, the topic of the workshop was “The Fast and the Furious: Energetic Phenomena in Isolated Neutron Stars, Pulsar Wind Nebulae and Supernova Remnants”; in 2015, the participants discussed “The Extremes of Black Hole Accretion”; in 2016, the workshop reflected on “XMM-Newton: The Next Decade”; in 2018, the workshop discussed “Time-Domain Astronomy: a High Energy View.” “Astrophysics of Hot Plasma in Extended X-ray Sources” was the 10th workshop in this series. I would like to take this opportunity to thank A. Decourchelle for chairing the Scientific Organizing Committee and all members of the Scientific Organizing Committee for the excellent and fruitful cooperation. I would like to thank S. Migliari for chairing the Local Organizing Committee and for coordinating the refereeing process. I am especially grateful to all Local Organizing Committee members for the efficient and professional organization of the workshop, which was essential for the overall success of the meeting.
