Effects of correlation between merging steps on the global halo formation
Jun Pan, Yougang Wang, Xuelei Chen +1
The excursion set theory of halo formation is modified by adopting the fractional Brownian motion, to account for possible correlation between merging steps. We worked out analytic…
Scale Transformations, Tree-level Perturbation Theory, and the Cosmological Matter Bispectrum
Jun Pan, Peter Coles, Istvan Szapudi
Scale transformations have played an extremely successful role in studies of cosmological large-scale structure by relating the non-linear spectrum of cosmological density fluctuat…
The fractional Brownian motion and the halo mass function
Jun Pan
The fractional Brownian motion with index is introduced to construct the fractional excursion set model. A new mass function with single parameter is derived within the for…
Colour Dependence of the Distribution of IRAS Galaxies revealed by Multifractal Measures
Jun Pan
Multifractal measures are applied to three IRAS galaxy subsamples selected by colour from the PSCz catalogue. As shown by generalised dimension spectrum, hot IRAS galaxies are foun…
The Monopole Moment of the Three-Point Correlation Function of the 2-degree Field Galaxy Redshift Survey
Jun Pan, Istvan Szapudi
We measure the monopole moment of the three-point correlation function on scales $1\mpc-70\mpc$ in the Two degree Field Galaxy Redshift Survey (2dFGRS). Volume limited samples are…
Fast Edge Corrected Measurement of the Two-Point Correlation Function and the Power Spectrum
István Szapudi, Jun Pan, Simon Prunet +1
We present two related techniques to measure the two-point correlation function and the power spectrum with edge correction in any spatial dimensions. The underlying algorithm uses…
