Answers from the void: VIDE and its applications
  We discuss various applications of VIDE, the Void IDentification and
Examination toolkit, an open-source Python/C++ code for finding cosmic voids in
galaxy redshift surveys and N-body simulations. Based on a substantially
enhanced version of ZOBOV, VIDE not only finds voids, but also summarizes their
properties, extracts statistical information, and provides a Python-based
platform for more detailed analysis, such as manipulating void catalogs and
particle members, filtering, plotting, computing clustering statistics,
stacking, comparing catalogs, and fitting density profiles. VIDE also provides
significant additional functionality for pre-processing inputs: for example,
VIDE can work with volume- or magnitude-limited galaxy samples with arbitrary
survey geometries, or dark matter particles or halo catalogs in a variety of
common formats. It can also randomly subsample inputs and includes a Halo
Occupation Distribution model for constructing mock galaxy populations. VIDE
has been used for a wide variety of applications, from discovering a universal
density profile to estimating primordial magnetic fields, and is publicly
available at http://bitbucket.org/cosmicvoids/vide_public and
http://www.cosmicvoids.net.
