XR SIG Seminar, 7 August 2026
A TDAMM Mission Concept Offered by the X-ray Timing Science Analysis Group: the Dynamic Extreme Universe in X-rays (DEUS-X) Machine The post XR SIG Seminar, 7 August 2026 appeared first on NASA Science .
On 7 August 2026, the X-ray Science Interest Group held a seminar focused on the future of X-ray astrophysics. The event was organized as part of the broader Physics of the Cosmos Community program. The seminar took place virtually, with details provided in the event announcement.
Physics of the Cosmos (PhysPAG) organized the seminar, which comprised several meetings and workshops for scientists at various stages of their careers. The organization sought to address gaps in current scientific understanding and explore new opportunities in the field.
The seminar featured a talk by Tom Maccarone, Krista Lynne Smith, and Zaven Arzoumanian, who discussed the "X-ray timing" approach to studying dynamic, often explosive cosmic phenomena. They emphasized that this method involves real-time analysis of lightcurves and spectroscopy across scales ranging from microseconds to years.
The researchers highlighted the need for advanced capabilities, such as wide-field surveys for X-ray transients and rapid multiwavelength follow-up of survey detections and other multi-messenger alerts. They presented the Dynamic Extreme Universe in X-rays (DEUS-X) mission concept, which envisions a fleet of spacecraft operating in two complementary configurations.
One configuration would provide uninterrupted coverage of the entire sky, excluding the Sun-avoidance cone, while the other would enable agile, highly efficient multiwavelength observations of new and known sources.
