Search for Gamma-Ray Spectral Lines from Dark Matter Annihilation up to 100 TeV toward the Galactic Center with MAGIC.

Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV.

Random laser as a potential tool for the determination of the scattering coefficient.

The determination of the optical properties of a turbid medium is a major topic in the field of optics. Generally, they comprise the parameters , , and . There is, however, a lack of techniques for the direct determination of the scattering coefficient .

From da Vinci's Flying Machines to a Theory of the Creative Process.

Steps involved in the creative process have been described in previous research, yet the exact nature of the process still remains unclear. In the current study, we take this investigation further, referring to two flying machines developed by Leonardo da Vinci and his other notes. Nine iterative steps are described with a focus on motivation and cognition: (a) vision and curiosity; (b) social recognition; (c) asking questions; (d) analogical thinking; (e) trial and error; (f) abductive reasoning; (g) incubation and forgetting; (h) overinclusive thinking, latent inhibition, and illumination; and (i) schema elaboration.

Original Unity.

Thomas Merton's vision of the original unity of humankind speaks of the oneness of the inner life of the Trinity. It is a vision that we need and one that the healers among us can offer us, whether they are acting as doctors or simply as Christians.

Bounds on Lorentz Invariance Violation from MAGIC Observation of GRB 190114C.

On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. We use this unique observation to probe an energy dependence of the speed of light in vacuo for photons as predicted by several quantum gravity models.
