A Halo-Based Galaxy Group Finder: Calibration and Application to the 2dFGRS
We use the halo occupation model to calibrate galaxy group finders in magnitudelimited redshift surveys. Since, according to the current scenario of structure formation, galaxy groups are associated with cold dark matter halos, we make use of the properties of the halo population in the design of our group finder. The method starts with an assumed mass-to-light ratio to assign a tentative mass ...
متن کاملGalaxy groups in the 2dFGRS: the group-finding algorithm and the 2PIGG catalogue
The construction of a catalogue of galaxy groups from the 2-degree Field Galaxy Redshift Survey (2dFGRS) is described. Groups are identified by means of a friends-offriends percolation algorithm which has been thoroughly tested on mock versions of the 2dFGRS generated from cosmological N-body simulations. The tests suggest that the algorithm groups all galaxies that it should be grouping, with ...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولGALAXY SPECTRAL TYPES AND THEIR APPLICATIONS IN THE 2dFGRS
The 2dF Galaxy Redshift Survey (2dFGRS) has already measured over 200,000 redshifts of nearby (median redshift z ∼ 0.1) galaxies. This is the single largest set of galaxy spectra ever collected. It allows us to subdivide the survey into subsets according to the galaxy intrinsic properties. We outline here a method (based on Principal Component Analysis) for spectrally classifying these galaxies...
متن کاملGalaxy groups in the 2dFGRS: the number density of groups
The abundance of galaxy clusters as a function of mass is determined using the 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue. This is used to estimate the amplitude of the matter fluctuation spectrum, parametrised by the linear theory rms density fluctuations in spheres of 8h Mpc, σ8. The best-fitting value for this parameter is highly correlated with the mean matter density in the...
