Search for Invisible Axion Dark Matter with the Axion Dark Matter Experiment. [PDF]

Physical Review Letters, 2018
This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81  μeV. The search excludes the range of axion-photon couplings predicted by plausible models of the invisible axion.

THE DARK-MATTER WORLD: ARE THERE DARK-MATTER GALAXIES? [PDF]

International Journal of Modern Physics: Conference Series, 2012
We attempt to answer whether neutrinos and antineutrinos, such as those in the cosmic neutrino background, would clusterize among themselves or even with other dark-matter particles, under certain time span, say 1 Gyr. With neutrino masses in place, the similarity with the ordinary matter increases and so is our confidence for neutrino clustering if ...

An Investigation of the Loop Oscillations after a Solar Flare

Universe
We study the loop oscillations after a solar flare on 19 January 2023, in the active region N11E40 3196, which is well observed by the SDO/AIA. After tracing the loop position and fitting, we find that the loop oscillations have a period between 3 and 9 ...

First Dark Matter Search Results from the XENON1T Experiment. [PDF]

Physical Review Letters, 2017
We report the first dark matter search results from XENON1T, a ∼2000-kg-target-mass dual-phase (liquid-gas) xenon time projection chamber in operation at the Laboratori Nazionali del Gran Sasso in Italy and the first ton-scale detector of this kind.

Gravitational effects of condensate dark matter on compact stellar objects

, 2012
We study the gravitational effect of non-self-annihilating dark matter on compact stellar objects. The self-interaction of condensate dark matter can give high accretion rate of dark matter onto stars.

Evolution of the Dark Matter Distribution at the Galactic Center [PDF]

, 2003
Annihilation radiation from neutralino dark matter at the Galactic center (GC) would be greatly enhanced if the dark matter were strongly clustered around the supermassive black hole (SBH).

Probable evidence for a transient mega-electron volt emission line in the GRB 221023A

Nature Communications
Detection of spectral line in gamma-ray bursts (GRBs) is importance for studying GRB physics, as it provides insights into the composition and physical conditions of the GRB environment.

AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space [PDF]

Experimental astronomy (Print), 2019
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range between the most sensitive ranges of LISA and the terrestrial LIGO/Virgo ...

WIMP Dark Matter and Baryogenesis

, 2010
In the present universe visible and dark matter contribute comparable energy density although they have different properties. This coincidence can be elegantly explained if the dark matter relic density, originating from a dark matter asymmetry, is fully

Getting the astrophysics and particle physics of dark matter out of next-generation direct detection experiments [PDF]

, 2010
The next decade will bring massive new data sets from experiments of the direct detection of weakly interacting massive particle (WIMP) dark matter. The primary goal of these experiments is to identify and characterize the dark-matter particle species ...
