Local redshift surveys and galaxy evolution

چکیده
We present observations of galaxy environmental dependencies using data from the 2dF Galaxy Redshift Survey. From a combined analysis of the luminosity function, Butcher-Oemler effect and trends in Hα line strengths we find support for a model where galaxy properties are mainly set by initial conditions at the time of their formation.

baryonic matter distribution in the large-scale structures is one of the main questions in cosmology. This distribution can provide valuable information regarding the processes of galaxy formation and evolution. On the other hand, the missing baryon problem is still under debate. One of the most important cosmological structures for studying the rate and the distribution of the baryons is gal...
متن کاملLas Campanas Redshift Survey Results: the 3d Power Spectrumand the Luminosity Function
Some recent results on the galaxy 3D power spectrum and the luminosity function derived from the Las Campanas Redshift Survey (LCRS) are discussed. We will present the LCRS power spectrum, compare it against results from other local redshift surveys, and use it to constrain a number of cold dark matter structure formation models. Then we will proceed to describe the LCRS luminosity function, as...
متن کاملThe local FIR Galaxy Colour-Luminosity distribution: A reference for BLAST, and Herschel/SPIRE sub-mm surveys
We measure the local galaxy far-infrared (FIR) 60-to-100μm colour-luminosity distribution using an all-sky IRAS survey. This distribution is an important reference for the next generation of FIR–submillimetre surveys that have and will conduct deep extra-galactic surveys at 250–500μm. With the peak in dust-obscured star-forming activity leading to present-day giant ellipticals now believed to o...

Recent observations have revealed a population of blue galaxies at intermediate redshift with a space density well in excess of expectations from the local luminosity function and standard cosmology. The colors and luminosities of these faint blue galaxies are similar to nearby low surface-brightness (LSB) galaxies. Such galaxies are severely underrepresented in surveys used to de ne the local ...

Galaxy redshift surveys are outstanding tools for observational cosmology because they produce large sample of standard galaxies at different cosmic epochs. Redshift acquisition has undergome tremendous progress thanks to advances in technology, and redshift surveys appear nowdays as routine. Even though they may look simple at face-value, the strategy of a survey and the galaxy-selection crite...
