A FUNDAMENTAL PLANE FOR LONG GAMMA-RAY BURSTS WITH X-RAY PLATEAUS [PDF]
, 2016 A class of long gamma-ray bursts (GRBs) presenting light curves with an extended plateau phase in their X-ray afterglows obeys a correlation between the rest-frame end-time of the plateau, Ta, and its corresponding X-ray luminosity, La, (Dainotti et al).

Model Constraints Based on the IceCube Neutrino Nondetection of GRB 221009A
The Astrophysical Journal, 2023 GRB 221009A is a bright gamma-ray burst (GRB) with isotropic energy larger than 10 ^54 erg. Its fairly low redshift makes it a promising candidate for high-energy neutrino detection.

Bulk Lorentz factors of Gamma-Ray Bursts [PDF]
, 2017 Knowledge of the bulk Lorentz factor $\Gamma_{0}$ of GRBs allows us to compute their comoving frame properties shedding light on their physics. Upon collisions with the circumburst matter, the fireball of a GRB starts to decelerate, producing a peak or a

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...

A burst in a wind bubble and the impact on baryonic ejecta: high-energy gamma-ray flashes and afterglows from fast radio bursts and pulsar-driven supernova remnants [PDF]
, 2016 Tenuous wind bubbles, which are formed by the spin-down activity of central compact remnants, are relevant in some models of fast radio bursts (FRBs) and super-luminous supernovae.
