“…For example, upgraded LSW experiments [195][196][197], experiments using atomic transitions [125,198,199], or Aharanov-Bohm experiments [200,201] may improve the purely-laboratory bounds on DPs. Whereas searches using X-ray [202] and radio [203,204] telescopes, fast radio burst timing [205], or asteroseismology [206], may improve upon existing astrophysical bounds.…”

The dark photon is a massive hypothetical particle that interacts with the Standard Model by kinetically mixing with the visible photon. For small values of the mixing parameter, dark photons can evade cosmological bounds to be a viable dark matter candidate. Due to the similarities with the electromagnetic signals generated by axions, several bounds on dark photon signals are simply reinterpretations of historical bounds set by axion haloscopes. However, the dark photon has a property that the axion does not: an intrinsic polarisation. Due to the rotation of the Earth, accurately accounting for this polarisation is nontrivial, and highly experiment-dependent. We show that if one does account for this polarisation, and the rotation of the Earth, experimental sensitivity to the dark photon's kinetic mixing parameter can be improved by over an order of magnitude. We detail the strategies that would need to be taken to properly optimise a dark photon search. These include judiciously choosing the location and orientation of the experiment, as well as strategically timing any repeated measurements. We also point out that several well-known searches for axions employ techniques for testing signals that preclude their ability to set exclusion limits on dark photons, and hence should not be reinterpreted as such.

“…They concluded that f DM in MACHO is constrained to < 0.001 when there were no search of multiplepeaked FRBs for time intervals larger than 1 ms and flux ratio less than 10 3 . These methods of using FRBs to find dark matter in MACHO is widely studied later [261][262][263][264][265].…”

In 2007, a very bright radio pulse was identified in the archival data of the Parkes Telescope in Australia, marking the beginning of a new research branch in astrophysics. In 2013, this kind of millisecond bursts with extremely high brightness temperature takes a unified name, fast radio burst (FRB). Over the first few years, FRBs seemed very mysterious because the sample of known events was limited. With the improvement of instruments over the last five years, hundreds of new FRBs have been discovered. The field is now undergoing a revolution and understanding of FRB has rapidly increased as new observational data increasingly accumulate. In this review, we will summarize the basic physics of FRBs and discuss the current research progress in this area. We have tried to cover a wide range of FRB topics, including the observational property, propagation effect, population study, radiation mechanism, source model, and application in cosmology. A framework based on the latest observational facts is now under construction. In the near future, this exciting field is expected to make significant breakthroughs. fast radio burst, neutron star, cosmology

“…Many authors [3][4][5][6] propose to discuss rotation curves of spiral galaxies with a spin integral S via gravi-magnetic fields or spin-spin interactions in general relativity (GR) to avoid the dark matter mystery. Despite a lot of thematic discussions and research efforts, the dark matter problem is still "one the biggest puzzles in cosmology" [7].…”

Temporal derivatives of the attracting mass in Newton’s law of distant interactions can balance the centripetal and centrifugal accelerations for the rotating periphery of a spiral galaxy. Thermal losses of the mass-energy integral inside the circle of rotation are the cause of the mega-vortex organization of the emitting galaxy. To reject dark matter in cosmic distributions, a conceptual modification of the Euler/Navier–Stokes hydrodynamics is required using adaptive tensor responses with metric waves but not gravimagnetic corrections from General Relativity.
