ESSC v6.4 — Residual Structure of the Radial Acceleration Relation and a Geometric Transition Band

Puntos clave

• This work aims to analyze the residuals of the radial acceleration relation in SPARC galaxies.
• Analyzed the radial acceleration relation using the SPARC galaxy sample
• Removed the leading dependence on halo fraction
• Investigated the persistence of radial structure in the residuals
• Found a weak but persistent radial structure remains after adjustments
• Identified a broad band in the residuals around R/Rd ≈ 2.5–3.5
• Indicated that the radial acceleration relation contains internal dynamical structure
