Topics of Discussion
Theory of Halo Boundaries:
- Definitions and properties of various halo boundaries (splashback radius, depletion radius, edge radius, phase-space boundary, classical virial/turnaround radius).
- The interplay between different halo boundary definitions and their theoretical implications.
- Methods for halo finding and statistical analysis using new boundary definitions.
- Characterization of halo boundaries using different tracers (dark matter, subhalo, galaxy, halo star, gas).
- Insights from machine learning on the structure and boundaries of halos.
- Advances in modeling the non-equilibrium outer regions of halos.
Implications and Applications of New Halo Boundaries:
- Probing cosmology, gravity, dark matter, and dark energy using new halo boundary definitions.
- Application of new halo boundaries in halo models for large-scale structure.
- Understanding the origins, evolution, and profiles of halos based on novel boundary characteristics.
- Detailed subhalo classification and modeling using advanced boundary concepts.
- Examining galaxy-halo connections and their implications for galaxy formation and evolution.
- Comparative studies of classical and modern halo boundary definitions in various cosmological contexts.
Observational Advances:
- Techniques for detecting and measuring new halo boundaries using lensing, dynamics, galaxy clustering, and gas observations.
- Case studies of observational surveys that successfully identified new halo boundary features.
- Integration of observational data with theoretical models and simulations to refine halo boundary definitions.
- Challenges and future prospects in observing and measuring diverse halo boundaries.
