Morphological Distribution of Galaxies in Some Nearby Clusters

open access: yesOpen Astronomy, 2019
We study the morphological distribution of galaxies in some nearby clusters, using the Sloan Digital Sky Survey – Data Release 9 (SDSS-DR9). The segregation between early-type galaxies and late-type ones is investigated in g – r / u – g color space ...

The Classification of Galaxy Morphology in the H Band of the COSMOS-DASH Field: A Combination-based Machine-learning Clustering Model

open access: yesThe Astrophysical Journal Supplement Series, 2023
By applying our previously developed two-step scheme for galaxy morphology classification, we present a catalog of galaxy morphology for H -band-selected massive galaxies in the COSMOS-DASH field, which includes 17,292 galaxies with stellar mass M _ ...

The minor role of gas-rich major mergers in the rise of intermediate-mass early types at z <~ 1 [PDF]

open access: yes, 2010
We study the evolution of galaxy structure since z ~ 1 to the present. From a GOODS-S multi-band catalog we define (blue) luminosity- and mass-weighted samples, limited by M_B = 10^10 M_Sun, comprising 1122 and 987 galaxies, respectively.

Age-density relation of Main galaxies at fixed parameters or for different galaxy families

open access: yesOpen Physics, 2015
Using two volume-limited Main galaxy samples of the Sloan Digital Sky Survey Data Release 10 (SDSS DR10), we examine the environmental dependence of galaxy age at fixed parameters or for different galaxy families.

The size distribution of galaxies in the Sloan Digital Sky Survey [PDF]

open access: yes, 2003
abridged: We use a complete sample of about 140,000 galaxies from the Sloan Digital Sky Survey (SDSS) to study the size distribution of galaxies and its dependence on their luminosity, stellar mass, and morphological type.

Intrinsic galaxy shapes and alignments I: Measuring and modelling COSMOS intrinsic galaxy ellipticities [PDF]

open access: yes, 2013
The statistical properties of the ellipticities of galaxy images depend on how galaxies form and evolve, and therefore constrain models of galaxy morphology, which are key to the removal of the intrinsic alignment contamination of cosmological weak ...

Galaxy morphology classification: are stellar circularities enough? [PDF]

open access: yesSerbian Astronomical Journal
We present a preliminary study exploring whether the stellar orbital circularity of simulated galaxies, available from precomputed catalogs in the IllustrisTNG project, can be used as a proxy for a broad morphological classification. We focus on

The population of early-type galaxies: how it evolves with time and how it differs from passive and late-type galaxies [PDF]

open access: yes, 2014
The aim of our analysis is twofold. On the one hand we are interested in addressing whether a sample of ETGs morphologically selected differs from a sample of passive galaxies in terms of galaxy statistics.
