Halo uncertainties in electron recoil events at direct detection experiments

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The dark matter direct detection rates are highly correlated with the phase space distribution of dark matter particles in our galactic neighbourhood.

Refinement of the standard halo model for dark matter searches in light of the Gaia Sausage

open access: yesPhysical Review D, 2019
Predicting signals in experiments to directly detect dark matter (DM) requires a form for the local DM velocity distribution. Hitherto, the standard halo model (SHM), in which velocities are isotropic and follow a truncated Gaussian law, has performed ...

An accurate tool for the fast generation of dark matter halo catalogues. [PDF]

open access: yes, 2013
We present a new parallel implementation of the PINpointing Orbit Crossing-Collapsed HIerarchical Objects (PINOCCHIO) algorithm, a quick tool, based on Lagrangian Perturbation Theory, for the hierarchical build-up of dark matter (DM) haloes in ...

On the Spatial Distribution of Dark Matter Halos [PDF]

open access: yesThe Astrophysical Journal, 1998
We study the spatial distribution of dark matter halos in the Universe in terms of their number density contrast, related to the underlying dark matter fluctuation via a non-local and non-linear bias random field. The description of the matter dynamics is simplified by adopting the `truncated' Zel'dovich approximation to obtain both analytical results ...

A New Method for Estimating Dark Matter Halo Masses using Globular Cluster Systems

open access: yes, 2008
All galaxies are thought to reside within large halos of dark matter, whose properties can only be determined from indirect observations. The formation and assembly of galaxies is determined from the interplay between these dark matter halos and the ...

Landscape of BRAF transcript variants in human cancer

open access: yesMolecular Oncology, EarlyView.
We investigate the annotation of BRAF variants, focusing on protein‐coding BRAF‐220 (formerly BRAF‐reference) and BRAF‐204 (BRAF‐X1). The IsoWorm pipeline allows us to quantify these variants in human cancer, starting from RNA‐sequencing data. BRAF‐204 is more abundant than BRAF‐220 and impacts patient survival.

Constraining the Gravitational Potential from the Projected Morphology of Extragalactic Tidal Streams

open access: yesThe Astrophysical Journal, 2023
The positions and velocities of stellar streams have been used to constrain the mass and shape of the Milky Way's dark matter halo. Several extragalactic streams have already been detected, though it has remained unclear what can be inferred about the ...

On the Possible Asymmetry in Gamma Rays from Andromeda Due to Inverse Compton Scattering of Star Light on Electrons from Dark Matter Annihilation

open access: yesGalaxies, 2023
Dark matter is a popular candidate to a new source of primary-charged particles, especially positrons in cosmic rays, which are proposed to account for observable anomalies.

CONSTRAINTS ON THE SHAPE OF THE MILKY WAY DARK MATTER HALO FROM THE SAGITTARIUS STREAM [PDF]

open access: yes, 2013
We propose a new model for the dark matter halo of the Milky Way that fits the properties of the stellar stream associated with the Sagittarius dwarf galaxy.

Effects of halo triaxiality, anisotropy and small scale clumping on WIMP direct detection exclusion limits

open access: yes, 2002
Weakly Interacting Massive Particle (WIMP) direct detection experiments are closing in on the region of parameter space where neutralinos may constitute the Galactic halo dark matter.
