Baryon dark matter
웹We propose new searches for n ′, a dark baryon that can mix with the Standard Model neutron.We show that IsoDAR, a proposal to place an intense cyclotron near a large-volume neutrino detector deep underground, can look for n → n ′ → n transitions with much lower backgrounds than surface experiments.

INTRODUCTION … 웹2014년 1월 24일 · In this figure dark matter is blue, baryons are green, and photons are red. Both recombination the baryon-photon fluid is red plus green which is yellow. After recombination the photons go off at the speed of light and baryons are left sitting in a spherical shell around the initial excess density of dark matter.

It is also found that such interactions affect the dark matter-baryon elastic scattering cross-section. The study also indicates the presence of multi component dark matter of different mass range in the Universe. png national housing corporation웹Due to the small shape noise and the shape of the lensing kernel, we find that a Dark Energy Task Force Stage IV version of such KWL survey can detect the BAO feature in dark matter by 3σ and measure the BAO scale at the precision level of 4 per cent, while it will be difficult to detect the feature in photometry-based weak lensing surveys. png national pandemic act웹The dark matter halo concentration can in that case increase by as much as 30 (10) per cent on galaxy (cluster) scales. The most significant effects occur in galaxies at high redshift, where there is a strong anticorrelation between the baryon fraction in the halo centre and the inner slope of both the total and the dark matter density profiles. png national maritime safety authority logo
