We present a comprehensive analysis of the evolution of the morphological and structural
properties of a large sample of galaxies at z= 3–9 using early James Webb Space …

We present a two-dimensional (2D) fitting algorithm (Galfit, ver. 3) with new capabilities to
study the structural components of galaxies and other astronomical objects in digital images …

We present global structural parameter measurements of 109,533 unique, H F160W-
selected objects from the CANDELS multi-cycle treasury program. Sérsic model fits for these …

We analyze the dependence of galaxy structure (size and Sérsic index) and mode of star
formation (Σ SFR and SFR IR/SFR UV) on the position of galaxies in the star formation rate …

The tight correlations between the masses of supermassive black holes (BHs) and the
properties of their host galaxies suggest that BHs co-evolve with galaxies. However, what is …

ABSTRACT I describe a new, open-source astronomical image-fitting program called imfit,
specialized for galaxies but potentially useful for other sources, which is fast, flexible, and …

We present single-Sérsic two-dimensional (2D) model fits to 167 600 galaxies modelled
independently in the ugrizYJHK bandpasses using reprocessed Sloan Digital Sky Survey …

Systematic studies,,–have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the
nearby Universe. With half-light radii rh of approximately 10–100 parsecs and stellar masses …

We have performed 2D bulge/bar/disc decompositions using g, r and i-band images of a
representative sample of nearly 1000 galaxies from the Sloan Digital Sky Survey. We show …
