Beyond the Disc--Spheroid Dichotomy at : Evidence for a Morphological Indeterminacy Regime from JWST

Igor Kolesnikov, Reinaldo Ramos de Carvalho, Jeong Hwan Lee +3

Galaxy morphology is a fundamental tracer of galaxy assembly, but its characterization becomes increasingly uncertain in the early Universe. We investigate morphological classifica…

The assembly of bulge-dominated galaxies: two evolutionary channels traced through morphology, kinematics, and environment with a hybrid classification pipeline

R. Flores-Freitas, R. R. de Carvalho, K. V. Nedkova +3

We investigate the physical origin of the bimodality in bulge-dominated galaxies, originally identified by Sampaio et al. (2025), by combining non-parametric morphological metrics,…

Morphology across cosmic time: assessing the evolution and interplay of disk and bulge-dominated galaxies in the CANDELS survey

Vitor M. Sampaio, Igor Kolesnikov, Reinaldo R. de Carvalho +2

We investigate the redshift evolution of disk and bulge-dominated galaxies using a mass-complete sample of 14,000 galaxies from the CANDELS survey, selected with $H_{\rm mag}…

Galaxy Morphology in CANDELS: Addressing Evolutionary Changes Across with Hybrid Classification Approach

I. Kolesnikov, V. M. Sampaio, R. R. de Carvalho +1

Morphological classification of galaxies becomes increasingly challenging with redshift. We apply a hybrid supervised-unsupervised method to classify galaxies in the…

Unveiling Galaxy Morphology through an Unsupervised-Supervised Hybrid Approach

I. Kolesnikov, V. M. Sampaio, R. R. de Carvalho +4

Galaxy morphology offers significant insights into the evolutionary pathways and underlying physics of galaxies. As astronomical data grows with surveys such as Euclid and Vera C.…
