Physicists new dark matter detection strategy
2017/11/23
Physicists from Brown University have devised a new strategy for directly detecting dark matter, the elusive material thought to account for the majority of matter in the universe.The new strategy, wh...
Dark Energy Survey reveals most accurate measurement of dark matter structure in the universe（图）
Dark Energy Survey most accurate measurement dark matter structure the universe

Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof tha...
Dark matter is likely ‘cold,’ not ‘fuzzy,’ scientists report after new simulations（图）
Dark matter cold not fuzzy scientists new simulations
2017/9/1
Scientists have never directly detected dark matter. But over decades, they have proposed a variety of theories about what type of material — from new particles to primordial black holes — could compr...

World most sensitive dark matter detector releases
2017/7/20
Scientists behind XENON1T, the largest dark matter experiment of its kind ever built, are encouraged by early results, describing them as the best so far in the search for dark matter.Dark matter is o...
A Yale-led team has produced one of the highest-resolution maps of dark matter ever created, offering a detailed case for the existence of cold dark matter — sluggish particles that comprise the bulk ...

The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its searc...
Galactic center's gamma rays unlikely to originate from dark matter,evidence shows
Galactic center gamma rays dark matter
2016/2/23
Bursts of gamma rays from the center of our galaxy are not likely to be signals of dark matter but rather other astrophysical phenomena such as fast-rotating stars called millisecond pulsars, accordin...
Dark matter is called "dark" for a good reason. Although they outweigh particles of regular matter by more than a factor of 5, particles of dark matter are elusive. Their existence is inferred by thei...
Fine-Tuning Implications of Direct Dark Matter Searches in the MSSM
Fine-Tuning Implications Direct Dark Matter Searches
2011/10/14
We study theoretical implications of direct dark matter searches in the minimal supersymmetric standard model (MSSM). We assume that no accidental cancellations occur in the spin-independent elastic n...
Light dark matter in the singlet-extended MSSM
Light dark matter the singlet-extended MSSM
2011/1/13
We discuss the possibility of light dark matter in a general singlet extension of the MSSM. Singlino LSPs with masses of a few GeV can explain the signals reported by the CRESST, CoGeNT and possibly ...
Evidence Against Dark Matter Halos Surrounding the Globular Clusters MGC1 and NGC 2419
Dark Matter Halos Surrounding the Globular Clusters MGC1 NGC 2419
2011/1/11
The conjecture that the ancient globular clusters (GCs) formed at the center of their own dark matter halos was first proposed by Peebles (1984), and has recently been revived to explain the puzzling ...
Latest results of the direct dark matter search with the EDELWEISS-2 experiment

2011/1/13
EDELWEISS-2 is a Ge-bolometer experiment located in the underground laboratory Laboratoire Souterrain de Modane (LSM, France). For the second phase of the experiment, the collaboration has developed n...
Dark Matter Halos: The Dynamical Basis of Effective Empirical Models
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We investigate the dynamical basis of the classic empirical models (specifically, Sersic-Einasto and generalized NFW) that are widely used to describe the distributions of collisionless matter in gala...
The Origin of Dark Matter Halo Profiles
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
A longstanding puzzle of fundamental importance in modern cosmology has been the origin of the nearly universal density profiles of dark matter halos found in N-body simulations -- the so-called NFW p...
Bound and unbound substructures in Galaxy-scale Dark Matter haloes
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We analyse the coarse-grained phase-space structure of the six Galaxy-scale dark matter haloes of the Aquarius Project using a state-of-the-art 6D substructure finder. Within r_50, we find that about ...
