Science theme: probing the physics of cosmic baryons with background light
Backlights and probes:
- CMB: kSZ, tSZ, and patchy screening
-
FRBs: dispersion measures
-
Quasars and galaxies: Lyα forest and absorption lines (including X-ray absorption)
-
Astrophysical systems: the halo–gas–galaxy connection in clusters, groups, galaxies, and the cosmic web
Simulations & methods:
-
Hydrodynamical simulations (CAMELS, TNG/TNG-Cluster, FLAMINGO, CROCODILE, COLIBRE, etc.)
-
Fast methods (Baryon pasting: Backlight, Gion, Mucho-Uchuu, AbacusSummit, AGORA, PINOCCHIO, etc)
-
New methods (AI/MI, SBI, etc)
Synergies and joint inference:
- combining backlights (e.g., kSZ x FRBs) and stacking on spectroscopic galaxy samples
The workshop follows the galaxy cluster conference at Tohoku University (May 10–14, 2027), so interested participants can attend both in a single trip to Japan. Those staying in Sendai over the weekend can also enjoy the Sendai Aoba Festival (May 15–16) and travel to Nagoya on Monday, May 17.
