Euclid preparation. Sensitivity to non-standard particle dark matter model
/ Euclid Collaboration
The Euclid mission of the European Space Agency will provide weak gravitational lensing and galaxy clustering surveys that can be used to constrain the standard cosmological model and its extensions, with an opportunity to test the properties of dark matter beyond the minimal cold dark matter paradigm. [...]

Gravitational waves $\times$ HI intensity mapping: cosmological and astrophysical applications

Two of the most rapidly growing observables in cosmology and astrophysics are gravitational waves (GW) and the neutral hydrogen (HI) distribution. In this work, we investigate the cross-correlation between resolved gravitational wave detections and HI signal from intensity mapping (IM) experiments. [...]

Lyman-$\alpha$ forest constraints on Primordial Black Holes as Dark Matter
/ Murgia, Riccardo (SISSA, Trieste ; IFPU, Trieste ; INFN, Trieste) ; Scelfo, Giulio (SISSA, Trieste ; INFN, Trieste ; IFPU, Trieste) ; Viel, Matteo (SISSA, Trieste ; IFPU, Trieste ; Trieste Observ.) ; Raccanelli, Alvise (CERN)
The renewed interest in the possibility that primordial black holes (PBHs) may constitute a significant part of the dark matter has motivated revisiting old observational constraints, as well as developing new ones. We present new limits on the PBH abundance, from a comprehensive analysis of high-resolution, high-redshift Lyman-$\alpha$ forest data. [...]

A White Paper on keV Sterile Neutrino Dark Matter

(Jamia Millia Islamia) ; Agostini, M. (Gran Sasso) ; Ky, N.Anh (Hanoi, Inst. Phys. ; Vietnam Natl. U.) ; Araki, T. (Saitama U.) ; Archidiacono, M. (Aarhus U.) ; Bahr, M. (UC, Santa Barbara) et al.
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and particle physics - in each case viewed from both theoretical and experimental/observational perspectives. After reviewing the role of active neutrinos in particle physics, astrophysics, and cosmology, we focus on sterile neutrinos in the context of the Dark Matter puzzle. [...]

Neutrino masses and cosmology with Lyman-alpha forest power spectrum

We present constraints on neutrino masses, the primordial fluctuation spectrum from inflation, and other parameters of the $\Lambda$CDM model, using the one-dimensional Ly$\alpha$-forest power spectrum measured by Palanque-Delabrouille et al. (2013) from SDSS-III/BOSS, complemented by Planck 2015 cosmic microwave background (CMB) data and other cosmological probes. [...]

Planck 2015 results. XIV. Dark energy and modified gravity
/ Planck Collaboration
We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG), beyond the cosmological constant scenario. We start with cases where the DE only directly affects the background evolution, considering Taylor expansions of the equation of state, principal component analysis and parameterizations related to the potential of a minimally coupled DE scalar field.

Planck 2015 results. I. Overview of products and scientific results
/ Planck Collaboration
The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14~May 2009 and scanned the microwave and submillimetre sky continuously between 12~August 2009 and 23~October 2013. In February~2015, ESA and the Planck Collaboration released the second set of cosmology products based on data from the entire Planck mission, including both temperature and polarization, along with a set of scientific and technical papers and a web-based explanatory supplement.
