Leo T is an extremely faint gas-rich Local Group satellite at roughly 420 kpc from the Milky Way with ongoing star formation and subtle gas-stellar morphology offsets (Irwin 2007; Ryan-Weber 2008; Simon 2019; Read 2024). ΛCDM treats Leo T as a CDM-dominated dwarf, but simultaneously explaining its high mass-to-light ratio, retained cold gas, gentle infall orbit, and gas-star morphology offset without fine-tuned halo + feedback + stripping combinations is challenging.
The standard model expects gas-rich dwarfs at Leo T's distance from the Milky Way to either retain gas (if undisturbed) or be stripped (if they passed through the halo). Leo T's gas-rich plus actively-star-forming plus distant configuration demands either special orbital history or modified stripping physics, neither of which is parsimonious.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, Leo T's gas retention is a cascade-seeded gas-content + gravitational-superposition signature. Pre-existing matter from prior cycles (P22, P25) gave Leo T a substantial cascade-thermalized gas reservoir at deposition. The reservoir was concentrated in a deep gravitational potential well from gravitational superposition (P50, P51): Φ_eff = Φ_local + Φ_mesh, where Φ_mesh from the Local Group cosmic-web context provides additional binding beyond what stellar mass alone supplies.
The deeper potential well (compared to a particle-DM model with similar M_star) holds the gas against gentle thermal escape and against the relatively weak ram-pressure stripping at Leo T's 420 kpc distance from the Milky Way. Angular-momentum inheritance (P31, P32) contributes to the gas-star morphology offset: the gas inherits a slightly different J component than the stars from cascade-stream substructure, producing the subtle spatial offset observed.
The same M6 framework that produces galaxy rotation curves without invoking exotic CDM particles (P54), the broader satellite-system dynamical mass (recid 130, 131), and the dwarf-galaxy mass-to-light ratios accounts for Leo T's gas retention. There is no need for special orbital history or modified stripping physics; the deeper coherent-mesh potential well naturally retains the gas at Leo T's distance and gentle infall.
If precision JWST + SKA Leo-T mapping finds gas dynamics fully consistent with particle-DM-halo predictions at the 5% level (no Φ_mesh contribution beyond standard CDM), the M6 coherent-mesh gas-retention explanation is refuted. The signature SCT prediction is Leo T's potential well being deeper than particle-DM expectations from M_star alone, by the Φ_mesh boost characteristic of its Local Group cosmic-web context.
