A New Approach to Large-Scale Nuclear Structure Calculations
A new approach to large-scale nuclear structure calculations, based on the Density Matrix Renormalization Group (DMRG), is described. The method is tested in the context of a problem involving many identical nucleons constrained to move in a single large-j shell and interacting via a pairing plus quadrupole interaction. In cases in which exact diagonalization of the hamiltonian is possible, the...
متن کاملRecent Advances in Large-Scale Structure and Galaxy Formation Studies
I review recent progress in the study of the large-scale structure of the Universe, covering the following areas: (1) Results from recently completed or ongoing redshift surveys of galaxies and X-ray clusters; (2) Measurements of the power spectrum of fluctuations approaching Gpc scales; (3) Redshift-space distortions and their cosmological use; (4) Structure at high redshifts and its connectio...
متن کاملLarge 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...
