Nexus of the Cosmic Web
Marius Cautun, Rien van de Weygaert, Bernard J. T. Jones +2
One of the important unknowns of current cosmology concerns the effects of the large scale distribution of matter on the formation and evolution of dark matter haloes and galaxies.…
Less is more: How cosmic voids can shed light on dark energy
E. G. Patrick Bos, Rien van de Weygaert, Jarno Ruwen +2
We showed how the shape of cosmic voids can be used to distinguish between different models of dark energy using galaxy positions.
NEXUS: Tracing the Cosmic Web Connection
Marius Cautun, Rien van de Weygaert, Bernard J. T. Jones
We introduce the NEXUS algorithm for the identification of Cosmic Web environments: clusters, filaments, walls and voids. This is a multiscale and automatic morphological analysis…
The darkness that shaped the void: dark energy and cosmic voids
E. G. Patrick Bos, Rien van de Weygaert, Klaus Dolag +1
Aims: We assess the sensitivity of void shapes to the nature of dark energy that was pointed out in recent studies. We investigate whether or not void shapes are useable as an obse…
Hot and cold spots counts as probes of non-Gaussianity in the CMB
Pravabati Chingangbam, Changbom Park, K. P. Yogendran +1
We introduce the numbers of hot and cold spots, and , of excursion sets of the CMB temperature anisotropy maps as statistical observables that can discriminate different…
The Sticky Geometry of the Cosmic Web
Johan Hidding, Rien van de Weygaert, Gert Vegter +2
In this video we highlight the application of Computational Geometry to our understanding of the formation and dynamics of the Cosmic Web. The emergence of this intricate and perva…
Skewness as a probe of Baryon Acoustic Oscillations
Roman Juszkiewicz, Wojciech A. Hellwing, Rien van de Weygaert
In this study we show that the skewness S_3 of the cosmic density field contains a significant and potentially detectable and clean imprint of Baryonic Acoustic Oscillations. Altho…
The Void Galaxy Survey: Optical Properties and H I Morphology and Kinematics
K. Kreckel, E. Platen, M. A. Aragón-Calvo +4
We have carefully selected a sample of 60 galaxies that reside in the deepest underdensities of geometrically identified voids within the SDSS. HI imaging of 55 galaxies with the W…
