The status of gamma-ray astronomy

open access: yes, 2011
Gamma-ray studies are an essential tool in our search for the origin of cosmic rays. Instruments like the Fermi-LAT, H.E.S.S., MAGIC and VERITAS have revolutionized our understanding of the high energy Universe. This paper describes the status of the very rich field of gamma-ray astrophysics that contains a wealth of data on Galactic and extragalactic ...

Ferrimagnetic Structure of 3C Pyrrhotite (Fe7S8) From Neutron Diffraction

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Pyrrhotite is a paleomagnetically important magnetic mineral in many geological settings. It forms numerous polytypes with different stacking patterns of the NiAs structure along the crystallographic c axis to produce different vacancy‐ordered superstructures.

On the Crustal Architecture of the Terrestrial Planets

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Understanding the structure and composition of planetary crusts is fundamental for unraveling the diverse geologic pathways of rocky bodies in the solar system. In recent years, geophysical missions have shed light on the crustal architecture of the Moon and Mars.

Python For Gamma-Ray Astronomy

open access: yes, 2016
Gamma-ray astronomy is a relatively new window on the cosmos. The first source detected from the ground was the Crab nebula, seen by the Whipple telescope in Arizona in 1989. Today, about 150 sources have been detected at TeV energies using gamma-ray telescopes from the ground such as H.E.S.S. in Namibia or VERITAS in Arizona, and about 3000 sources at

Industrial Gamma Radiation Signals: An Untapped Resource to Reconstruct Neogene Paleoclimate Off Northwest Australia

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Paleoceanographic reconstructions require both high‐resolution temporal records and high‐density spatial coverage. Scientific drilling provides detailed paleoclimate time‐series, but its spatial distribution limits our ability to capture regional climate dynamics.

Leptohadronic Multimessenger Modeling of Two High-redshift (z > 1) Neutrino Emission Blazar Candidates

open access: yesThe Astrophysical Journal
The blazars are one of the leading candidate sources of high-energy neutrinos. Recently, two blazars have been found to be temporally and spatially correlated with some IceCube high-energy neutrino events. The two blazars, GB6 J2113+1121 and NVSS J171822+

Decoding Pain: Next‐Generation In Vitro Systems for Mechanistic Insights and Drug Discovery

open access: yesThe FASEB Journal, Volume 39, Issue 16, 31 August 2025.
Developing an in vitro pain model that mimics essential features of the in vivo pain circuit requires careful consideration of multiple components and choices. These include selecting the cellular population for the model, choosing from the origin of nociceptors and other cells that are cultured, deciding between 3D or 2D dimensions, designing the ...

Search for Kink Events in Variable Fermi-LAT Blazars

open access: yesThe Astrophysical Journal
This study explores the detection of quasiperiodic oscillations (QPOs) in blazars as a method to identify kink events within their jets, utilizing both γ -ray and polarized light observations. Focusing on a sample of nine blazars, we analyze γ -ray light
