Legume genome structures and histories inferred from Cercis canadensis and Chamaecrista fasciculata genomes

The Plant Journal, Volume 126, Issue 5, June 2026.
SUMMARY The legume family originated ca. 60–65 million years ago and soon diversified into at least six lineages (now extant subfamilies). The signal of whole genome duplications (WGD) is apparent in species sampled from all six subfamilies. The early diversification has posed difficulties for resolving the legume backbone structure and the timing of ...

Observation of a Downward Terrestrial Gamma‐Ray Flash Associated With Dart Leaders of a Negative Cloud‐To‐Ground Lightning Flash

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract We report the observation of a downward terrestrial gamma‐ray flash (TGF) during the dart‐leader stage in a negative cloud‐to‐ground lightning flash. The observation was recorded by the Telescope Array Surface Detector, in conjunction with a Lightning Mapping Array, an interferometer (INTF), a fast antenna, and a high‐speed camera.

Direct Ionosonde Evidence of F‐Layer Disturbances Driven by Intense Lightning Activity at Low Latitudes

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Thunderstorms could cause the irregularities of electron density distributions in the ionosphere by exciting gravity waves and modifying ambient electric field (E‐field). By comparing the DPS‐4D ionosonde observation at 5‐min resolution at Fuke Station in Hainan, China with the lightning detection data, we studied the F‐layer responses to a ...

Searches for low-energy counterparts of gamma-ray bursters

Advances in Space Research, 1986
The results of six studies concerning the identification of low-energy counterparts of gamma-ray bursters (GRBs) are reported. From these results, it is concluded that the near-infrared observations of GRBs from IRAS pose serious difficulties for several GRB models.

Neutron stars and the distance to gamma-ray bursters

Publications of the Astronomical Society of the Pacific, 1991
Assuming that gamma-ray bursts originate from galactic neutron stars, an analytic method for studying their statistical properties is outlined. If a significant fraction of all neutron stars are born with space velocities of less than approximately 100 km/s, as suggested by studies of pulsar statistics, then the sampling distance to gamma-ray burst ...

Gamma-Ray Bursters

, 2010
The role of an amateur astronomer has changed. When I started out, in 1930 (!), an amateur was concerned mainly with the Solar System, and usually with one particular object, in my case the Moon. There were some amateurs who were variable star enthusiasts, but not many and amateur photography was rudimentary.

Radio Emission from Supernovae and Gamma-Ray Bursters

Annual Review of Astronomy and Astrophysics, 2002
▪ Abstract  Study of radio supernovae over the past 20 years includes two dozen detected objects and more than 100 upper limits. From this work it is possible to identify classes of radio properties, demonstrate conformance to and deviations from existing models, estimate the density and structure of the circumstellar material and, by inference, the ...
