“…There are five (cryogenic) resonant mass detectors which are now operating: NIOBE [300] (Perth, Australia), ALLEGRO [301] (Baton Rouge, Lousiana, USA), AURIGA [302] (Legnaro, Italy), EXPLORER [303] (Geneva, Switzerland) and NAU-TILUS [304] (Frascati, Italy). They all have cylindrical shape (the are "bars").…”

This review presents, in a self-consistent manner, those analytical tools that are relevant for the analysis of the physics of CMB anisotropies generated in different theoretical models of the early Universe. After introducing the physical foundations of the Sachs-Wolfe effect, the origin and evolution of the scalar, tensor and vector modes of the geometry is treated in both gauge-invariant and gauge-dependent descriptions. Some of the recent progresses in the theory of cosmological perturbations are scrutinized with particular attention to their implications for the adiabatic and isocurvature paradigms, whose description is reviewed both within conventional fluid approaches and within the the Einstein-Boltzmann treatment. Open problems and theoretical challenges for a unified theory of the early Universe are outlined in light of their implications for the generation of large-scale anisotropies in the CMB sky and in light of the generation of stochastic backgrounds of relic gravitons between few Hz and the GHz.

“…The heat and vibration energy generated in ordinary matter due to the passage of mirror matter dust particles can potentially be observed in sensitive cryogenic detectors, such as the NAUTILUS gravitational wave detector [25]. NAUTILUS consists of an aluminum 2300 Kg bar cooled to 0.1 Kelvin.…”

Slow-moving (v ∼ 15 km/s) 'dark matter particles' have allegedly been discovered in a recent experiment. We explore the possibility that these slow moving dark matter particles are small mirror matter dust particles originating from our solar system. Ways of further testing our hypothesis, including the possibility of observing these dust particles in cryogenic detectors such as NAUTILUS, are also discussed.

“…The experimental efforts are converging towards the possibility of direct detection of stochastically distributed gravitational waves [19,20]. Various resonant mass detectors are now operating at a typical frequency of the order of kHz (Allegro [21], Auriga [22], Explorer [23], Nautilus [24], Niobe [25]) and four Michelson interferometers (GEO-600 [26],TAMA-400 [27], LIGO [29] and VIRGO [28]) will soon be operating in a wide frequency band from a few Hz up to 10 kHz. It is interesting, in the context of ABBN, to elaborate on the possibility that the additional relativistic species are of gravitational origin.…”

Big bang nucleosynthesis, matter-antimatter regions, extra relativistic species, and relic gravitational waves

Provided that matter-antimatter domains are present at the onset of big bang nucleosynthesis (BBN), the number of allowed additional relativistic species increases, compared to the standard scenario when matter-antimatter domains are absent. The extra relativistic species may take the form of massless fermions or even massless bosons, like relic gravitons. The number of additional degrees of freedom compatible with BBN depends, in this framework, upon the typical scale of the domains and the antimatter fraction. Since the presence of matter-antimatter domains allows a reduction of the neutron to proton ratio prior to the formation of 4 He, large amounts of radiation-like energy density are allowed. Our results are compared with other constraints on the number of supplementary relativistic degrees of freedom and with different nonstandard BBN scenarios where the reduction of the neutron to proton ratio occurs via a different physical mechanism. The implications of our considerations for the upper limits on stochastic gravitational waves backgrounds of cosmological origin are outlined.
