Compact groups in theory and practice - III. Compact groups of galaxies in the Sixth Data Release of the Sloan Digital Sky Survey
Alan McConnachie, David Patton, Sara Ellison +1
We present the largest publicly available catalogue of compact groups of galaxies identified using the original selection criteria of Hickson, selected from the Sixth Data Release…
Predictability on finite horizon for processes with exponential decrease of energy on higher frequencies
Nikolai Dokuchaev
The paper presents sufficient conditions of predictability for continuous time processes in deterministic setting. We found that processes with exponential decay on energy for high…
Compact groups in theory and practice - II. Comparing the observed and predicted nature of galaxies in compact groups
Crystal M. Brasseur, Alan W. McConnachie, Sara L. Ellison +1
We examine the properties of galaxies in compact groups identified in a mock galaxy catalogue based upon the Millennium Run simulation. The overall properties of groups identified…
Effect of CuO chains on the local density of states in the vortex phase of YBa_2Cu_3O_7
W. A. Atkinson
We examine the effects of the CuO chains on the density of states in the vortex phase in YBa_2Cu_3O_7, via a calculation based on the tight-binding proximity model. In this model,…
The Luminosity Dependence of the Galaxy Merger Rate
D. R. Patton, J. E. Atfield
We measure the number of companions per galaxy (Nc) as a function of r-band absolute magnitude for both the Sloan Digital Sky Survey and the Croton et al. (2006) semi-analytic cata…
Compact groups in theory and practice - I. The spatial properties of compact groups
Alan W. McConnachie, Sara L. Ellison, David R. Patton
We use a mock galaxy catalogue based upon the Millennium Run simulation to investigate the intrinsic spatial properties of compact groups of galaxies. We find that approximately 30…
