Search for nonvirialized axionic dark matter

چکیده
Cold dark matter in the Milky Way halo may have structure defined by flows with low velocity dispersion. The Axion Dark Matter eXperiment high resolution channel is especially sensitive to axions in such low velocity dispersion flows. Results from a combined power spectra analysis of the high resolution channel axion search are presented along with a discussion of the assumptions underlying such an analysis. We exclude Kim-Shifman-Vainshtein-Zakharov axion dark matter densities of * 0:2 GeV=cm and Dine-Fischler-Srednicki-Zhitnitskii densities of * 1:4 GeV=cm over a mass range of ma 1⁄4 3:3 eV to 3:69 eV for models having velocity dispersions of & 3 10 .

Ultra Light Axionic Dark Matter: Galactic Halos and Implications for Observations with Pulsar Timing Arrays
The cold dark matter (CDM) paradigm successfully explains the cosmic structure over an enormous span of redshifts. However, it fails when probing the innermost regions of dark matter halos and the properties of the Milky Way’s dwarf galaxy satellites. Moreover, the lack of experimental detection of Weakly Interacting Massive Particle (WIMP) favors alternative candidates such as light axionic da...
متن کاملWeak Gravitational Lensing by Dark Clusters
We calculate the abundance of dark-matter concentrations that are sufficiently overdense to produce a detectable weak-gravitational-lensing signal. Most of these overdensities are virialized halos containing identifiable X-ray and/or optical clusters. However, a significant fraction are nonvirialized, cluster-mass, overdensities still in the process of gravitational collapse—these should produc...
متن کاملPossible resonance effect of axionic dark matter in S/N/S Josephson junctions
We provide theoretical arguments that dark matter axions from the galactic halo that pass through the earth may generate a small observable signal in resonant S/N/S Josephson junctions. The corresponding interaction process is based on uniqueness of the gauge-invariant axion Josephson phase angle modulo 2π and is predicted to produce a small Shapiro step-like feature without externally applied ...
متن کاملAxion physics in a Josephson junction environment
We show that recent experiments based on Josephson junctions, SQUIDs, and coupled Josephson qubits have a cosmological interpretation in terms of axionic dark matter physics, in the sense that they allow for analogue simulation of early-universe axion physics. We discuss new experimental setups in which SQUID-like axionic interactions in a resonant Josephson junction environment can be tested, ...
