CDN-230: Separation Events

Key Points

The study aims to set the separation-event anchor rule for dark matter structures and analyze baryon contributions.
Investigated a two-component merger topology with collisional gas baryons and collisionless stars.
Analyzed gas-traced response dynamics relative to baryon survival rates and alignment with galaxy lenses.
Found that gas-traced response peaks near collisional baryons but fails overall.
Identified that lensing peaks align with galaxies when source survival of collisionless clusters is 8.71 times greater than gas sources.

Abstract

CDN-230 locks the separation-event anchor rule for the GCFT dark-matter arc. In a two-component merger topology with 90% collisional gas baryons and 10% collisionless galaxy/star baryons, a gas-traced response peaks near the gas and fails. Using the CDN-229 inherited response-to-baryon ratio, the lensing peak aligns with the galaxy side only when collisionless source survival is about 8.71 times gas-source survival. This is not an observed Bullet Cluster fit; it is the required GCFT condition for surviving Bullet-class separation topology.
