The morphological diversities among star-forming galaxies at high redshifts in the great observatories origins deep survey
high-redshift fundamental parameters
2014/12/24
We used the deep, multiwavelength images obtained by the Great Observatories Origins Deep Survey (GOODS) to identify ~4700 Lyman break galaxies (LBGs) at z > 2.5, and 292 starburst galaxies at z ~ 1.2...
Advanced Morphological Galaxy Classification: A Comparison of Real and Simulated Galaxies
galaxies: structure — galaxies: evolution — methods: numerical
2011/10/18
Encoded within the morphological structure of galaxies are clues related to their formation and evolutionary history. Recent advances pertaining to the statistics of galaxy morphology include sophisti...
From Bipolar to Elliptical: Simulating the Morphological Evolution of Planetary Nebulae
From Bipolar Elliptical: Simulating Morphological Evolution Planetary Nebulae
2011/9/27
The majority of Proto-planetary nebulae (PPN) are observed to have bipolar morphologies. The majority of mature PN are observed to have elliptical shapes. In this paper we address the evolution of PPN...
Galaxy stellar mass functions of different morphological types in clusters, and their evolution between z=0.8 and z=0
Galaxy stellar mass functions morphological types
2011/1/10
We present the galaxy stellar mass function (MF) and its evolution in clusters from z~0.8 to the current epoch, based on the WIde-field Nearby Galaxy-cluster Survey (WINGS) (0.04
Automated Morphological Classification of SDSS Red Sequence Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
In the last decade, the advent of enormous galaxy surveys has motivated the development of automated morphological classification schemes to deal with large data volumes. Existing automated schemes ca...
Morphological Properties of Superclusters of Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We studied superclusters of galaxies in a volume-limited sample extracted from the Sloan Digital Sky Survey Data Release 7 (SDSS/DR7) and from mock catalogues based on a semi-analytical model of galax...
