Star Formation Rate and Environment in the SDSS-DR4 | | G. Sorrentino

26 Jan 2007 | | Abstract: | We investigate the environmental dependence of galaxies with the star formation rate (SFR) in a complete volume limited sample of 91566 galaxies, in the redshift range $0.05 le z le 0.095$, and with $M_r=-20.0$ (that is M$^*$ + 1.45), selected from the Sloan Digital Sky Survey Data Release 4 (SDSS-DR4). The environment is characterized by the local number density of galaxies, defined by the parameter $Sigma_{N}(frac{N}{pi*r_{N}^{2}})$, with N=5. We find a reletaion between the distance of the nearest neighbour and the SFR, and confirm the general trend for the SFR of decreasesing with increasing density. | | Source: | arXiv, astro-ph/0701760 | | Services: | Forum | Review | PDF | Favorites | |
