Large Scale Structure survey
Galaxy groups and low-mass clusters provide important laboratories in which to study X-ray gas physics and the interplay between galaxy evolution and environmental effects. The X-ray Multi-Mirror (XMM) Large Scale Structure (LSS) survey has currently imaged 5 deg 2 to a nominal extended source flux limit of order 10 −14 ergs s −1 cm −2 and is dominated numerically by low-mass groups and cluster...
متن کاملLarge scale structure
I give a review of catalogues of galaxies, clusters of galaxies and superclusters – sources of information to study the large-scale structure of the Universe. Thereafter I shall discuss the power spectrum of density perturbations, and the correlation function – principal description functions which characterize the large-scale structure. I shall pay special attention to the geometric interpreta...
متن کاملSimulating Large - Scale Structure
After two decades of direct dynamical simulation of large–scale structure in the universe, it is safe to say the subject is now " mature ". Still, there are parts of the problem that are less well developed than others. In general, the collisionless dynamics of the dark matter component is better understood than the collisional gas dynamics of the baryonic component. In situations where the gas...
متن کاملInflation for Large Scale Structure
Two extensions of ideas lying in the basis of the inflationary scenario of the early Universe and their effect on the large scale structure of the present-day Universe are discussed. The first of them is the possibility of fast phase transitions in physical fields other than an inflaton scalar field during inflation and nor far from the end of it. This results in the appearance of specific feat...
متن کاملLarge-Scale Structure & Future Surveys
As the 2dF Galaxy Redshift Survey and Sloan Digital Sky Survey move toward completion, it is time to ask what the next generation of survey of large-scale structure should be. I discuss some of the cosmological justifications for such surveys and conclude that surveys at z = 3 offer a critical advantage in their ability to access linear-regime clustering at scales smaller than any current surve...
