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

open access: yesInternational 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

The Phenomena of High Energy Astrophysics [PDF]

open access: yesSymposium - 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 ...

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

open access: yesExperimental 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]

open access: yesAnnals 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.

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

open access: yes, 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 ...

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

open access: yesElectromagnetic 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 ...

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

open access: yes, 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-

Oscillations and waves in solar spicules [PDF]

open access: yes, 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.

Galaxy Formation Theory [PDF]

open access: yes, 2010
We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of baryonic material we describe the analytical and numerical

Observation of collapsing radiative shocks in laboratory experiments [PDF]

open access: yes, 2006
This article reports the observation of the dense, collapsed layer produced by a radiative shock in a laboratory experiment. The experiment uses laser irradiation to accelerate a thin layer of solid-density material to above 100 km/s100km∕s, the first to
