How well does galaxy clustering constrain cosmology?
On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...
Hunting down systematics in baryon acoustic oscillations after cosmic high noon
Future dark energy experiments will require accurate theoretical predictions for the baryon acoustic oscillations (BAOs). Here, we use large N-body simulations...
Hunting for VIPERS red nuggets - traces of the past
Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...
Hyper Suprime-Cam (HSC) project for the SUBARU telescope
In 2006, NAOJ proposed to construct the Hyper Suprime-Cam (HSC) as a second generation instrument for Subaru telescope. This is a very wide-field camera...
Hα kinematics of the Spitzer Infrared Nearby Galaxies Survey - II
This is the second part of an Hα kinematics follow-up survey of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample. The aim of this paper is to shed new...
Impact of baryon physics on dark matter structures: a detailed simulation study of halo density profiles
The back-reaction of baryons on the dark matter halo density profile is of great interest, not least because it is an important systematic uncertainty when...
Impact of internal bremsstrahlung on the detection of γ rays from neutralinos
We present a detailed study of the effect of internal bremsstrahlung photons in the context of the minimal supersymmetric standard models and their impact on γ...
Implications for galaxy formation models from observations of globular clusters around ultradiffuse galaxies
We present an analysis of Hubble Space Telescope observations of globular clusters (GCs) in six ultradiffuse galaxies (UDGs) in the Coma cluster, a sample that...
Intracluster light: a luminous tracer for dark matter in clusters of galaxies
The bulk of stars in galaxy clusters are confined within their constituent galaxies. Those stars do not trace the extended distribution of dark matter well as...
