Neutron detection at the extremes of sensitivity in the cosmic environment. [PDF]
, 2000 This paper compares and contrasts the use of MOSFET dosimeters and extended rem counters for neutron detection in cosmic radiation fields. These technologies have been exposed to a reference field and data are presented that demonstrate the contrasting ...

The Astrophysical Journal, 2017 Abstract The network of filaments with embedded clusters surrounding voids, which has been seen in maps derived from redshift surveys and reproduced in simulations, has been referred to as the cosmic web. A complementary description is provided by considering the shear in the velocity field of galaxies.

Understanding the cosmic web [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractWe investigate the characteristics and the time evolution of the cosmic web from redshift,z=2, to present time, within the framework of the \nexus{} algorithm. This necessitates the introduction of new analysis tools optimally suited to describe the very intricate and hierarchical pattern that is the cosmic web. In particular, we characterising

Jupiter as a giant cosmic ray detector [PDF]
, 2014 All authors highlight financial support of the European Community under the FP7 by an ERC starting grant.We explore the feasibility of using the atmosphere of Jupiter to detect ultra-high-energy cosmic rays (UHECRs).

The Observational Signatures of Cosmic Strings [PDF]
, 2009 Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification models and in theories with extended additional dimensions.

Multiscale Phenomenology of the Cosmic Web
Monthly Notices of the Royal Astronomical Society, 2010 We analyze the structure and connectivity of the distinct morphologies that define the Cosmic Web. With the help of our Multiscale Morphology Filter (MMF), we dissect the matter distribution of a cosmological $Λ$CDM N-body computer simulation into cluster, filaments and walls.

Electrons in the cosmic radiation [PDF]
, 1990 The nature of cosmic ray electrons and their radiation in the Universe has been studied. A convection associated diffusion model is proposed to describe the main characteristics of the large-scale distribution of cosmic ray electrons in the Galaxy: (1) a

Voids and the Cosmic Web: cosmic depression & spatial complexity [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractVoids form a prominent aspect of the Megaparsec distribution of galaxies and matter. Not only do they represent a key constituent of the Cosmic Web, they also are one of the cleanest probes and measures of global cosmological parameters. The shape and evolution of voids are highly sensitive to the nature of dark energy, while their substructure

Connecting clustering and the cosmic web
Astronomy & AstrophysicsContext. Cosmological simulations predict significant secondary dependences of halo clustering on a variety of internal halo properties, and on environmental factors.
