August 18-20, 2026

Cambridge, MA

Organized by the Chandra X-ray Center

The landscape of time domain and multi-messenger astrophysics (TDAMM) is undergoing a rapid transformation. Chandra’s unprecedented angular and spectral resolutions offer unique diagnostic tools that have driven breakthroughs in time domain astronomy, and which are poised to continue driving valuable future discoveries.

In this workshop, we will explore exciting time domain science enabled by Chandra across various timescales, such as investigating supernova explosions and their remnants, characterizing X-ray counterparts to gravitational wave merger events, identifying new Galactic and extragalactic transients, discerning the structure of relativistic jets, uncovering stellar populations, monitoring stellar variability, studying end points of stellar evolution, detecting X-rays from tidal disruption events, and enabling studies of accretion in extreme regimes.

We will highlight Chandra’s unique science capabilities, such as localizing X-ray transients to arcsecond positions, long-term monitoring to very low flux levels, grating spectroscopy of bright transients, and monitoring rapid decay in transients. The workshop will also emphasize the critical role that Chandra plays in joint investigations with current and upcoming multi-wavelength and multi-messenger astronomical facilities.

As part of the workshop, we will explore ways in which Chandra can continue to best serve the evolving interests of the TDAMM community, including the possibility of community target-of-opportunity (TOO) programs, and other strategies to bolster the already-robust Chandra TOO program.
