Impact of Warm Dark Matter on the Cosmic Neutrino Background Anisotropies

  title={Impact of Warm Dark Matter on the Cosmic Neutrino Background Anisotropies},
  author={Christopher G. Tully and Gemma Zhang},
The Cosmic Neutrino Background (CνB) anisotropies for massive neutrinos are a unique probe of large-scale structure formation. The redshift-distance measure is completely different for massive neutrinos as compared to electromagnetic radiation. The CνB anisotropies in massive neutrinos grow in response to non-relativistic motion in gravitational potentials seeded by relatively high k-modes. Differences in the early phases of large-scale structure formation in warm dark matter (WDM) versus cold…

Implementation and optimization of the PTOLEMY transverse drift electromagnetic filter

The PTOLEMY transverse drift filter is a new concept to enable precision analysis of the energy spectrum of electrons near the tritium β-decay endpoint. This paper details the implementation and



Multi-messenger astrophysics with the cosmic neutrino background

The massive neutrinos of the Cosmic Neutrino Background (CνB) are fundamental ingredients of the radiation-dominated early universe and are important non-relativistic probes of the large-scale


▪ Abstract In forthcoming years, connections between cosmology and particle physics will become increasingly important with the advent of a new generation of cosmic microwave background (CMB)

The non-linear matter power spectrum in warm dark matter cosmologies

We investigate the non-linear evolution of the matter power spectrum by using a large set of high-resolution N-body/hydrodynamic simulations. The linear matter power in the initial conditions is

On general features of warm dark matter with reduced relativistic gas

Reduced relativistic gas (RRG) is a useful approach to describe the warm dark matter (WDM) or the warmness of baryonic matter in the approximation when the interaction between the particles is

Quantum induced broadening: A challenge for cosmic neutrino background discovery

A recent preprint by Cheipesh et al. pointed out that the zero-point motion of Tritium atoms bound to Graphene may blur the measured energies of β electrons. Smearing due to zero point motion is well

Equation of state, universal profiles, scaling and macroscopic quantum effects in warm dark matter galaxies

The Thomas–Fermi approach to galaxy structure determines self-consistently and non-linearly the gravitational potential of the fermionic warm dark matter (WDM) particles given their quantum

First direct neutrino-mass measurement with sub-eV sensitivity

We report the results of the second measurement campaign of the Karlsruhe Tritium Neutrino (KATRIN) experiment. KATRIN probes the effective electron anti-neutrino mass, mν, via a high-precision

νCONCEPT: cosmological neutrino simulations from the non-linear Boltzmann hierarchy

In this paper the non-linear effect of massive neutrinos on cosmological structures is studied in a conceptually new way. We have solved the non-linear continuity and Euler equations for the

Heisenberg ’ s uncertainty as a limiting factor for neutrino mass detection in β-decay

In order to explore the potential of beta-decay experiments to detect relic neutrinos (CνB), we study the intrinsic irreducible uncertainty in energy of electrons resulting from the zero-point motion
