Description and modeling of the Jiddat al Harasis 091 L5 strewn field
Meteoritics &Planetary Science, EarlyView.Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

Meteoritics &Planetary Science, EarlyView.Abstract Samples returned from asteroid Ryugu by the Hayabusa2 mission are dominated by fine‐grained matrix material made of phyllosilicates and nanosulfides. Here, we report the mineralogical, textural, and chemical characteristics of nanosulfide‐rich regions identified in Ryugu particles.

Quasi-Periodic Oscillations from Low-Mass X-Ray Binaries with Neutron Stars
, 2004 Before the launch of the Rossi X-ray Timing Explorer (RXTE) it was recognized that neutron star accretion disks could extend inward to very near the neutron star surface, and thus be governed by millisecond timescales.

Exposing and Challenging “Grit” in Physics Education
Science Education, Volume 110, Issue 1, Page 102-116, January 2026.ABSTRACT In STEM education, grit is increasingly the focus of research, with scholars and educators seeking to develop and test interventions that will enhance persistence. As part of the special issue Centering Affect and Emotion Toward Justice and Dignity in Science Education, in this paper, we use interviews with 12 white physics faculty to show ...

Stellar structure and compact objects before 1940: Towards relativistic astrophysics
, 2017 Since the mid-1920s, different strands of research used stars as "physics laboratories" for investigating the nature of matter under extreme densities and pressures, impossible to realize on Earth.

Spectral Analysis of Flickering Gamma‐Ray Flashes Observed During the ALOFT 2023 Campaign
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.Abstract We examine a newly discovered category of high‐energy radiation events called flickering gamma‐ray flashes (FGF) detected during the airborne lightning observatory for FEGS and TGFs campaign in July 2023. These FGFs are characterized by highly pulsating gamma‐ray emissions that have no detectable concurrent optical or radio signals (Ostgaard ...

Advanced Photonics Research, Volume 6, Issue 12, December 2025.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...
