Adaptive Multiscale Detection of Filamentary Structures Embedded in a Background of Uniform Random Points
Multiscale Geometric Analysis Pattern Recognition
2015/8/21
We are given a set of n points that appears uniformly distributed in the unit square [0,1]2.
We wish to test whether the set actually is generated from a non-uniform distribution having
a small frac...
A deep spectroscopic study of the filamentary nebulosity in NGC4696, the brightest cluster galaxy in the Centaurus cluster

2011/10/12
We present results of deep integral field spectroscopy observations using high resolution optical (4150-7200 A) VIMOS VLT spectra, of NGC 4696, the dominant galaxy in the Centaurus cluster (Abell 3526...

2010/12/16
The recently introduced discrete persistent structure extractor (DisPerSE Soubie 2010, paper I) is implemented on realistic 3D cosmological simulations and observed redshift catalogues; it is found th...

We construct a filament catalogue using an extension of the halo based filament finder
of Zhang et al. (2009), in a 250 Mpc/h side N-body simulation, and study the prop-
erties of filaments ending u...
Filamentary structure in the 2dFGRS

We have designed and applied a simple algorithm for defining filamentary structures in galaxy redshift surveys.

We present DisPerSE, a novel approach to the coherent multi-scale identification of all types of astrophysical structures, and in particular the filaments, in the large scale distribution of matter in...
