abstract
In this paper we describe some analytical properties of the R^{1/m} law proposed by Sersic (1968) to categorize the photometric profiles of elliptical galaxies. In particular, we present the full asymptotic expansion for the dimensionless scale factor b(m) that is introduced when referring the profile to the standard effective radius. Surprisingly, our asymptotic analysis turns out to be useful even for values of m as low as unity, thus providing a unified analytical tool for observational and theoretical investigations based on the R^{1/m} law for the entire range of interesting photometric profiles, from spiral to elliptical galaxies.

Multi-scale radio observations of 15 local U/LIRGs decompose emission to show nuclear components contribute ~50% on average while diffuse SF-related emission dominates ~80% of total power, with radio excess linked to AGN rather than boosted star formation.
NIRCam-selected AGN hosts split into a 'bridge' group with moderate-to-low SFRs and a 'branch' group above the SFMS with SFR rising with AGN fraction; both populations show recent transitions between star formation and quiescence.
Simulations combining MICADO imaging and HARMONI kinematics show that variations in nuclear star cluster inner surface-brightness slope affect IMBH mass estimates derived via Jeans Anisotropic Modeling.
Dropout in an AlexNet-based CNN raises R² to ~0.96 and reduces SIE parameter errors by 60-76% on simulated galaxy-galaxy lens images.
