Galaxy Star Formation as a function of Environment

TLDR
In this article, the authors studied the galaxy star formation rate as a function of environment using the SDSS EDR data and found that the suppression of the SFR starts to be noticeable at around 4 virial radii.
Abstract
We study the galaxy star formation rate (SFR) as a function of environment using the SDSS EDR data. We nd that the SFR is depressed in dense environments (clusters and groups) compared to the eld. We nd that the suppression of the SFR starts to be noticeable at around 4 virial radii. We nd no evidence for SF triggering as galaxies fall into the clusters. We also present a project to study these eects in cluster pairs systems where the eects of lamen ts and large scale structure may be noticeable.

The physical properties of star-forming galaxies in the low-redshift universe

TL;DR: In this article, the authors present a comprehensive study of the physical properties of ∼ 10 5 galaxies with measurable star formation in the Sloan Digital Sky Survey (SDSS) by comparing physical information extracted from the emission lines with continuum properties, and build up a picture of the nature of star-forming galaxies at z < 0.2.

The environmental dependence of the relations between stellar mass, structure, star formation and nuclear activity in galaxies

TL;DR: In this article, the authors used a sample of galaxies drawn from the Sloan Digital Sky Survey to study how structure, star formation and nuclear activity depend on local density and on stellar mass.

Semi‐empirical analysis of Sloan Digital Sky Survey galaxies – I. Spectral synthesis method

TL;DR: In this paper, the authors investigate the power of spectral synthesis as a means to estimate the physical properties of galaxies, including stellar mass, velocity dispersion, extinction, and emission lines.

The Sloan Digital Sky Survey: Technical Summary

Donald G. York
- 27 Jun 2000 - 
TL;DR: The Sloan Digital Sky Survey (SDSS) as mentioned in this paper provides the data to support detailed investigations of the distribution of luminous and non-luminous matter in the Universe: a photometrically and astrometrically calibrated digital imaging survey of pi steradians above about Galactic latitude 30 degrees in five broad optical bands.

The Luminosity function and stellar evolution

TL;DR: In this paper, the evolutionary significance of the observed luminosity function for main-sequence stars in the solar neighborhood is discussed and it is shown that stars move off the main sequence after burning about 10 per cent of their hydrogen mass and that stars have been created at a uniform rate in a solar neighborhood for the last five billion years.

The Structure of cold dark matter halos

TL;DR: In this article, high-resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple universal profile.

Star formation in galaxies along the hubble sequence

TL;DR: In this article, the authors focus on the broad patterns in the star formation properties of galaxies along the Hubble sequence and their implications for understanding galaxy evolution and the physical processes that drive the evolution.
