Gamma-ray Astronomy

, 2007
The relevance of gamma-ray astronomy to the search for the origin of the galactic and, to a lesser extent, the ultra-high-energy cosmic rays has long been recognised. The current renaissance in the TeV gamma-ray field has resulted in a wealth of new data on galactic and extragalactic particle accelerators, and almost all the new results in this field ...

Real‐Time Rendering Framework for Holography

Computer Graphics Forum, EarlyView.
Abstract With the advent of holographic near‐eye displays, the need for rendering algorithms that output holograms instead of color images emerged. These holograms usually encode phase maps that alter the phase of coherent light sources such that images result from diffraction effects.

Experimental Gamma-Ray Astronomy [PDF]

Journal of Physics: Conference Series, 2012
Our knowledge of the γ-ray sky has dramatically changed due to the advent of the new ground-based Imaging Atmospheric Cherenkov Telescopes (H.E.S.S., MAGIC and VEPJTAS) and the satellite-borne instruments (AGILE and Fermi). These facilities boosted the number of γ-ray sources by one order of magnitude in the last 6 years, providing us with about 2000 ...

Empirical Functions for Highly Charged Ion Abundances in Solar Wind Charge Exchange Models: Addressing Post‐2011 ACE Data Limitations

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Upcoming imaging missions—NASA's LEXI and ESA/CAS's SMILE—will target solar wind charge exchange X‐ray (SWCX) emission from Earth's magnetosheath. This emission is generated by highly charged ions colliding with neutrals in Earth's exosphere.

Journey of X-ray astronomy: Indian perspectives [PDF]

arXiv
X-ray astronomy is a mature area of observational astronomy. After the discovery of the first non-solar X-ray source in 1962, X-ray astronomy proliferated during the Apollo era's space race. Then, it matured as an established area of research during the period of Great Observatories, and now it has become an indispensable tool to understand a wide ...

Astronomy in Argentina [PDF]

arXiv, 2012
This article analyses the current state of Astronomy in Argentina and describes its origins. We briefly describe the institutions where astronomical research takes place, the observational facilities available, the training of staff and professionals, and the role of the institutions in scientific promotion.

Efficiency of Thermoremanent Magnetization Acquisition in Vortex‐State Particle Assemblies

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Magmatic rocks record ambient magnetic fields during cooling, preserving them for billions of years through thermoremanent magnetization (TRM). TRM accuracy depends on particle size, shape, magnetic properties, and the number of particles available to record the field.
