SummaryThe Future Large Gamma-ray Mission Concepts working group will hold a hybrid work session to review progress and needed inputs for a technical report on gamma-ray instrumentation. Working group members will present updates and lead discussions to complete gathering of input on gamma-ray capabilities, mission concepts, and technologies. The group will work on identifying and filling gaps in the draft and refining the content of the report.

Session TitleHEAD: Toward the 2030 Decadal: Science Cases for Potential Future X-ray Mission Concepts
Session ChairBreanna Binder
SummaryThis special session will present outcomes from four X-ray Science Interest Group (XRSIG)-led Science Analysis Groups (SAGs) convened to evaluate potential future X-ray mission concepts and their scientific return. Over the past ~year, the SAGs conducted an initial exploration of science enabled by four candidate mission architectures: (1) a Lynx-like observatory concept with potential augmentations, (2) an ultra-high angular resolution X-ray interferometer mission, (3) a mission spanning a substantially broader energy band than would be feasible for a Lynx-like design, and (4) a dedicated X-ray timing mission concept. In this session, we will summarize the scope, activities, and key findings of each SAG, highlighting representative science cases, capability-driven requirements, and points of convergence and differentiation across the architectures. We will also review relevant technology developments identified by the SAGs that could improve mission feasibility and inform community discussions as planning proceeds toward the next Decadal Survey.

This cropped horizontal image has layers of semi-opaque rusty red colored gas and dust that starts at the bottom right and goes toward the top left. There are three prominent pillars rising toward the top left. The left pillar is the largest and widest. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines.
