The alignments between galaxies, their underlying matter structures, and the cosmic web
constitute vital ingredients for a comprehensive understanding of gravity, the nature of …

Abstract Weak isosinglet Neutral Heavy Leptons (vm) have been searched for using data
collected by the DELPHI detector corresponding to 3.3× 10 6 hadronic Z 0 decays at LEP1 …

We measure the anisotropy of dark matter flows on small scales (∼ 500 kpc) in the near
environment of haloes using a large set of simulations. We rely on two different approaches …

The large-scale structure (LSS) in the Universe comprises a complicated filamentary
network of matter. We study this network using a high-resolution simulation of structure …

We have identified over 2000 well-resolved cluster halos, and also their associated bound
subhalos, from the output of a 1024 3 particle cosmological N-body simulation (of box size …

ABSTRACT We present VIMOS-Very Large Telescope (VLT) spectroscopy of the Frontier
Fields cluster MACS J0416. 1-2403 (z= 0.397). Taken as part of the CLASH-VLT survey, the …

In this paper we study the iron content of a sample of 22 nearby hot clusters observed with
BeppoSAX. We find that the global iron mass of clusters is tightly related to the cluster …

Results of a systematic study of substructure in X-ray surface brightness distributions of a
combined sample of 470 REFLEX+ BCS clusters of galaxies are presented. The fully …

Nearby clusters such as Virgo and Coma possess galaxy distributions that tend to be
aligned with the principal axis of the cluster itself. This has also been confirmed by a recent …

We search for and find fossil evidence that the spin axes of galaxies in cosmic web filaments
relative to their host filaments are not randomly distributed. This indicates the fact that the …
