The ultrafast time-integrated diagnosis of ions plays a vital role in high-energy-density physics research. However, it is extremely challenging to measure in experiment.

Source Count Distribution of Fermi LAT Gamma-Ray Blazars Using Novel Nonparametric Methods
We utilized a sample from the Fermi-LAT 14-year Source Catalog by adjusting the flux detection threshold, enabling us to derive the intrinsic source count distribution dN/dF25 of extragalactic blazars using nonparametric, unbinned methods developed by ...

In this paper, we report our multi-angle observations of the transverse oscillation of a prominence and a filament induced by an EUV wave originating from the far side of the Sun on 2014 September 1. The prominence oscillation was simultaneously observed

Searches for dark matter particles through cosmic ray measurements
We consider the hypothesis that dark matter is made of weakly interacting massive particles (WIMPs) and describe how their pair annihilation in the galactic halo generates exotic cosmic ray fluxes.

Precise measurement of CP violating τ EDM through e + e − → γ *, ψ(2s) → τ + τ −
A nonzero electric dipole moment of a tauon, d τ , signals CP violation and provides an important probe for new physics. We study methods to measure d τ at low energy e + e − colliders through the processes e + e − → γ *, ψ(2S) → τ + τ − with τ ± decays ...

Dark matter in Sa galaxies: NGC 2179 and NGC 2775
We present measurements of the stellar and ionized gas velocity curves and velocity dispersion profiles along the major axis for two Sa galaxies, NGC 2179 and NGC 2775. The luminosity profiles and the stellar kinematics of each galaxy are used to compute

Molecular hydrogen as dark mass in dwarf galaxies
We report here an example of a series of computer simulations of the formation of disk galaxies, including a standard cold dark matter component, gas, and star formation, which result in objects which closely resemble observed giant galaxies, with a ...

Dark Matter Ring and Dark Matter - Book: "Philosophy Unscrambles Dark Matter"
This section of the book deals with the official claim that Dark Matter Ring is like an evidence or at least a solid indicator for the the existence of dark matter. This section evaluates and rejects this claim.

Extending global fits of 4D Composite Higgs Models with partially composite leptons
We perform the first convergent Bayesian global fits of 4D Composite Higgs Models with partially-composite third generation quarks and leptons based on the minimal SO(5) → SO(4) symmetry breaking pattern.

Is dark matter made up of massive quark objects? [Elektronisk resurs]
We suggest that dark matter is made up of massive quark objects that have survived from the Big Bang, representing the ground state of "baryonic'' matter. Hence, there was no overall phase transition of the original quark matter, but only a split-up into
