Introduction to high-energy gamma-ray astronomy [PDF]

, 2015
The present issue is the first of of a two-volume review devoted to gamma-ray astronomy above 100 MeV which has witnessed considerable progress over the last 20 years.

Rényi divergences from Euclidean quenches

Journal of High Energy Physics, 2020
We study the generalisation of relative entropy, the Rényi divergence D α (ρ∥ρ β ) in 2d CFTs between an excited state density matrix ρ, created by deforming the Hamiltonian, and the thermal density matrix ρ β .

Gravitational Waves and Time Domain Astronomy [PDF]

, 2011
The gravitational wave window onto the universe will open in roughly five years, when Advanced LIGO and Virgo achieve the first detections of high frequency gravitational waves, most likely coming from compact binary mergers. Electromagnetic follow-up of

A Thousand Invisible Cords Binding Astronomy and High-Energy Physics

, 2007
The traditional realm of astronomy is the observation and study of the largest objects in the Universe, while the traditional domain of high-energy physics is the study of the smallest things in nature. But these two sciences concerned with opposite ends

GrAviPaSt’s Lens to the Past: Unveiling the Evolution of Filamentary Structures

The Astrophysical Journal
This paper examines the evolution of cosmic filaments across redshifts 1, 0.5, and 0 using the IllustrisTNG100-1 magnetohydrodynamical simulation. To achieve this, we introduce GrAviPaSt, a simple, efficient, and parameter-free filament identification ...

Highest Energy Cosmic Rays

, 2004
We review the current state and future prospect of ultra high energy cosmic ray physics and the relationship between cosmic rays and gamma-ray astrophysics.Comment: 12 pages, in the proceedings of the Gamma 2004 Symposium on High-Energy Gamma-Ray ...

High energy processes in microquasars [PDF]

, 2005
Microquasars are X-ray binary stars with the capability to generate relativisticjets. It is expected that microquasars are gamma-ray sources, because of the analogy with quasars and because the theoretical models predict emission at such energy range. In

Highlights from the Telescope Array

EPJ Web of Conferences, 2016
The Telescope Array measures the properties of ultra high energy cosmic ray induced extensive air showers. We do this using a variety of techniques including an array of scintillator detectors to sample the footprint of the air shower when it reaches the

Long-lived biνo at the LHC

Journal of High Energy Physics, 2021
We examine the detection prospects for a long-lived biνo, a pseudo-Dirac bino which is responsible for neutrino masses, at the LHC and at dedicated long-lived particle detectors.
