Clustering of HI galaxies in the HI parkes all sky survey and arecibo legacy fast alfa survey
(Oxford University Press, 2011)
We investigate the clustering of H I-selected galaxies in the Arecibo Legacy Fast ALFA
Survey (ALFALFA) and compare results with those obtained for the H I Parkes All Sky
Survey (HIPASS). Measurements of the angular ...
Disentangling non-gaussianity, bias, and general relativistic effects in the galaxy distribution
(American Physical Society, 2012)
Local non-Gaussianity, parametrized by
f
NL
, introduces a scale-dependent bias that is strongest at large scales, precisely where general relativistic (GR) effects also become significant. With future data, it should ...
Nonlinear galactic dynamos and the magnetic pitch angle
(American Astronomical Society, 2015)
Pitch angles p of the large-scale magnetic fields B of spiral galaxies have previously been inferred from
observations to be systematically larger in magnitude than predicted by standard mean-field dynamo theory. ...
