Mass Dependence of the RECT Parameter C: Results from SPARC and NSA Galaxy Samples

Key Result

This paper provides a preprint and analysis code for the mass-dependent response of the RECT parameter C in spiral and mixed galaxy populations.

Key Points

This research aims to evaluate how the RECT parameter varies with mass in different types of galaxies.
Analysis of spiral and mixed galaxy populations from SPACE and NSA samples.
Utilization of empirical relations defined by C_eff = Σ_star^(-0.6).
Development of Python scripts for data reproduction and analysis.
The RECT parameter C shows a significant mass dependence in galaxy populations.
Empirical relations derived from SPACE samples align with those observed in NSA samples.

Abstract

This upload contains the preprint and supporting analysis code for the paper: "Mass-Dependent Response of RECT Parameter C in Spiral and Mixed Galaxy Populations: Evidence from SPACE and NSA Random Samples" The repository includes: - The full preprint PDF - Core Python scripts to reproduce Table 1 and the main figures - Additional analysis scripts for the SPACE and NSA samples All NSA-related codes use Cₑff = Σₛtar^ (-0. 6), following the empirical relation observed in the SPACE sample.
