GrailQuest: hunting for atoms of space and time hidden in the wrinkle of Space-Time [PDF]

Experimental Astronomy, 2021
AbstractGrailQuest(Gamma Ray Astronomy International Laboratory for QUantum Exploration of Space-Time) is a mission concept based on a constellation (hundreds/thousands) of nano/micro/small-satellites in low (or near) Earth orbits. Each satellite hosts a non-collimated array of scintillator crystals coupled with Silicon Drift Detectors with broad ...

Lorentz violation at high energy: Concepts, phenomena, and astrophysical constraints [PDF]

Annals of Physics, 2006
We consider here the possibility of quantum gravity induced violation of Lorentz symmetry (LV). Even if suppressed by the inverse Planck mass such LV can be tested by current experiments and astrophysical observations. We review the effective field theory approach to describing LV, the issue of naturalness, and many phenomena characteristic of LV.

The Phenomena of High Energy Astrophysics [PDF]

Symposium - International Astronomical Union, 2003
A brief summary of some highlights in the study of high energy astrophysical sources over the past decade is presented. It is argued that the great progress that has been made derives largely from the application of new technology to observation throughout all of the electromagnetic and other spectra and that, on this basis, the next decade should be ...

Similarity Properties and Scaling Laws of Radiation Hydrodynamic Flows in Laboratory Astrophysics [PDF]

, 2011
The spectacular recent development of modern high-energy density laboratory facilities which concentrate more and more energy in millimetric volumes allows the astrophysical community to reproduce and to explore, in millimeter-scale targets and during ...

A UNIFIED MODEL OF HIGH-ENERGY ASTROPHYSICAL PHENOMENA [PDF]

International Journal of Modern Physics A, 2005
I outline a unified model of high-energy astrophysics, in which the gamma background radiation, cluster "cooling flows", gamma-ray bursts, X-ray flashes and cosmic-ray electrons and nuclei of all energies — share a common origin. The mechanism underlying these phenomena is the emission of relativistic "cannonballs" by ordinary supernovae, analogous to

HIGH ENERGY APPROACHES TO LOW ENERGY PHENOMENA IN ASTROPHYSICS [PDF]

Electromagnetic Interactions in Nuclear and Hadron Physics, 2002
Studies in nuclear astrophysics have long been associated with long runs at small accelerators, measuring ever-decreasing cross sections as one approached (but rarely reached) the energy of reactions in stars. But in recent years pioneering studies have shown that studies at high-energy accelerators can often yield the same information, and in some ...

Oscillations and waves in solar spicules [PDF]

, 2009
Since their discovery, spicules have attracted increased attention as energy/mass bridges between the dense and dynamic photosphere and the tenuous hot solar corona.

Similar phenomena at different scales: Black Holes, the Sun, Gamma-ray Bursts, Supernovae, Galaxies and Galaxy Clusters [PDF]

, 2007
Many similar phenomena occur in astrophysical systems with spatial and mass scales different by many orders of magnitudes. For examples, collimated outflows are produced from the Sun, proto-stellar systems, gamma-ray bursts, neutron star and black hole X-

General relativity and relativistic astrophysics

, 2016
Einstein established the theory of general relativity and the corresponding field equation in 1915 and its vacuum solutions were obtained by Schwarzschild and Kerr for, respectively, static and rotating black holes, in 1916 and 1963, respectively.
