09/11/2023 10:00

We analyse in all generality beyond Horndeski theories of shift symmetry in a static and spherically symmetric spacetime. By introducing four auxiliary functions, we write the field equations in a particularly compact form. We show that assuming additionally parity symmetry renders the system directly integrable giving multiple families of black-hole solutions. These have typically an...

42. Diffuse gamma-ray and neutrino background from Galactic Ridge
Dmitri Semikoz
14/11/2023 11:30

We show that the IceCube observation of the Galactic neutrino flux component confirms the hint of detection of neutrinos from the Galactic Ridge (the inner part of the Milky Way disk within the Galactic longitude |l|<30 degrees), previously reported by the ANTARES collaboration. This confirmation indicates that the bulk of the high-energy flux from the Galactic Ridge in multi-TeV band is...

Imagine a world where each "thing" comes with AI built-in. Your phone video app, to assure that you enjoy uninterrupted service, intelligently buffers the video and requests a varying number of packets ahead, using predictive models about you, the video you are watching, and the world. The mobile base station allocates frequencies, roams phones, focuses beams intelligently to serve all phones...
