Implications of Large- QCD for the NN Interaction
Thomas R. Richardson, Matthias R. Schindler, Roxanne P. Springer
We present a method for ordering two-nucleon interactions based upon their scaling with the number of QCD colors, , in the limit that becomes large. Available data in th…
A non-parametric approach to the relation between the halo mass function and internal dark matter structure of haloes
T. R. G. Richardson, P. -S. Corasaniti
Context. Galaxy cluster masses are usually defined as the mass within a spherical region enclosing a given matter overdensity (in units of the critical density). Converting masses…
Forecasting cosmological parameter constraints using multiple sparsity measurements as tracers of the mass profiles of dark matter haloes
P. S. Corasaniti, A. M. C. Le Brun, T. R. G. Richardson +4
The dark matter halo sparsity, i.e. the ratio between spherical halo masses enclosing two different overdensities, provides a non-parametric proxy of the halo mass distribution whi…
Timing the last major merger of galaxy clusters with large halo sparsity
T. R. G. Richardson, P. -S. Corasaniti
Numerical simulations have shown that massive dark matter haloes, which today host galaxy clusters, assemble their mass over time alternating periods of quiescent accretion and pha…
Large- constraints for elastic dark matter-light nucleus scattering in pionless effective field theory
Thomas R. Richardson, Xincheng Lin, Son T. Nguyen
Recent proposals for the use of light nuclei as dark matter direct detection targets necessitate a strong theoretical understanding of the nuclear physics involved. We perform rele…
Large- analysis of two-nucleon neutrinoless double beta decay and charge-independence-breaking contact terms
Thomas R. Richardson, Matthias R. Schindler, Saori Pastore +1
The interpretation of experiments that search for neutrinoless double beta decay relies on input from nuclear theory. Cirigliano et al. recently showed that, for the light Majorana…
Non-Halo Structures and their Effects on Gravitational Lensing
T. R. G. Richardson, J. Stücker, R. E. Angulo +1
Anomalies in the flux-ratios of the images of quadruply-lensed quasars have been used to constrain the nature of dark matter. Assuming these lensing perturbations are caused by dar…
Large- analysis of magnetic and axial two-nucleon currents in pionless effective field theory
Thomas R. Richardson, Matthias R. Schindler
We analyze magnetic and axial two-nucleon contact terms in a combined large- and pionless effective field theory expansion. These terms play important roles in correctly descr…
On the dark matter profile in Sculptor: Breaking the degeneracy with Virial shape parameters
Thomas Richardson, Malcolm Fairbairn
We present a new method for studying tracers in gravitational systems where higher moments of the line-of-sight velocity distribution are introduced via Virial equations rather tha…
Plan beta: Core or Cusp?
Thomas Richardson, Douglas Spolyar, Matt Lehnert
The inner profile of Dark Matter (DM) halos remains one of the central problems in small-scale cosmology. At present, the problem can not be resolved in dwarf spheroidal galaxies d…
Cores in Classical Dwarf Spheroidal Galaxies? A Dispersion-Kurtosis Jeans Analysis Without Restricted Anisotropy
Thomas Richardson, Malcolm Fairbairn
We attempt to measure the density of dark matter in the two Dwarf Spheroidal Galaxies Fornax and Sculptor using a new method which employs Jeans equations based on both the second…
Analytical Solutions to the Mass-Anisotropy Degeneracy with Higher Order Jeans Analysis: A General Method
Thomas Richardson, Malcolm Fairbairn
The Jeans analysis is often used to infer the total density of a system by relating the velocity moments of an observable tracer population to the underlying gravitational potentia…
