The Distribution of Galaxies in Relation to Their Formation and Evolution [PDF]
Symposium - International Astronomical Union, 1974 The distribution of galaxies on the sky is not random, but has structure on a scale of ~ 30 Mpc. Similar structure in the cosmic background radiation is not present. Another expected source of structure in the background radiation is the finite size of the light horizon in the early Universe. The lack of observable structure in the background radiation

Chemical evolution of galaxies and galaxy formation mechanisms [PDF]
Proceedings of Baryons in Dark Matter Halos — PoS(BDMH2004), 2004 I will describe the results if models for the chemical evolution of galaxies of different morphological type (ellipticals, spirals and irregulars), and compare them with observations in order to impose constraints on the mechianisms of formation and evolution of galaxies.

Evolution of the star formation efficiency in galaxies [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractThe physical and chemical evolution of galaxies is intimately linked to star formation, We present evidence that molecular gas (H2) is transformed into stars more quickly in smaller and/or subsolar metallicity galaxies than in large spirals – which we consider to be equivalent to a star formation efficiency (SFE).

A Survey of Galaxy Pairs in the SDSS Photometric Images based on Faster-RCNN
The Astronomical JournalGalaxy pairs hold significant importance in understanding the evolution of galaxies, and the extensive search for a large sample of galaxy pairs is meaningful.

SNe feedback and the formation of elliptical galaxies
, 2006 The processes governing both the formation and evolution of elliptical galaxies are discussed by means of a new multi-zone photo-chemical evolution model for elliptical galaxies, taking into account detailed nucleosynthetic yields, feedback from ...

Dissipative N - body code for galaxy evolution
, 2000 The evolving galaxy is considered as a system of baryonic fragments embedded into the static dark nonbaryonic (DH) and baryonic (BH) halo and subjected to gravitational and viscous interactions.

The Open Journal of AstrophysicsRadial metallicity gradients are fundamental to understanding galaxy formation and evolution. In our high-resolution simulation of a NIHAO-UHD Milky Way analogue, we analyze the linearity, scatter, spatial coherence, and age-related variations of ...
