The Void Phenomenon

By P. Peebles, Joseph Henry. 2001

273 citations recorded by the source corpus.

Advances in theoretical ideas on how galaxies formed have not been strongly influenced by the advances in observations of what might be in the voids between the concentrations of ordinary optically selected galaxies. The theory and observations are maturing, and the search for a reconciliation offers a promising opportunity to improve our understanding of cosmic evolution. I comment on the development of this situation and present an update of a nearest neighbor measure of the void phenomenon that may be of use in evaluating theories of galaxy formation.

Is there a "too big to fail" problem in the field? (2014, background): “…discrepancies have been discovered in the field in various contexts, e.g. related to the paucity of low-mass galaxies in voids (“void phenomenon”; Peebles 2001), the sizes of mini-voids in the Local Volume (Tikhonov & Klypin 2009), or the slowly rising galaxy velocity function (Zwaan et al.…”

Cosmic Voids in Sloan Digital Sky Survey Data Release 7 (2011, background): “Peebles (2001) describes the “void phenomenon”: galaxies of all types appear to respect the same voids, in contrast to the prediction of CDM that low density regions should contain many low mass objects.”
The Dependence of Halo Clustering on Halo Formation History, Concentration, and Occupation (2005, background): “The currently favored CDM model predicts substantial mass in voids, so the absence of galaxies in these regions has been suggested to be a potentially serious problem for the prevailing paradigm (Peebles 2001).”
A hierarchy of voids: much ado about nothing (2003, background): “In recent years, the possibility that void galaxies are a systematically different population has received considerable attention (see e.g. Szomoru et al. 1996; El-Ad & Piran 2000; Peebles 2001; Mathis & White 2002, Rojas et al. 2003; Benson et al. 2003).”

Unusually Large Fluctuations in the Statistics of Galaxy Formation at High Redshift (2003, background): “However, voids are observed to be rather deficient in dwarf galaxies as well as in larger galaxies on the scale of the Milky Way (e.g., Kirshner et al. 1981; Eder et al. 1989; Grogin & Geller 1999, 2000; El-Ad & Piran 2000; Peebles 2001).”
