The Temporal Symmetrical and Translational Structure in Gamma-Ray Burst Light Curves

open access: yesThe Astrophysical Journal, 2023
Tremendous information is hidden in the light curve of a gamma-ray burst (GRB). Based on Compton Gamma Ray Observatory/Burst And Transient Source Experiment (BATSE) data, Hakkila found a majority of GRBs can be characterized by a smooth, single-peaked ...

Stripping Model for Short Gamma-Ray Bursts in Neutron Star Mergers

open access: yesParticles, 2022
We overview the current status of the stripping model for short gamma-ray bursts. After the historical joint detection of the gravitational wave event GW170817 and the accompanying gamma-ray burst GRB170817A, the relation between short gamma-ray bursts ...

Exploring the connection between compact object mergers and fast X-ray transients

open access: yesAstronomy & Astrophysics
Context. The connection between compact object mergers and some extragalactic fast X-ray transients (FXRTs) has long been hypothesised but never ultimately established. Aims.

Revisiting the Parameter Space of Binary Neutron Star Merger Event GW170817

open access: yesThe Astrophysical Journal, 2023
Since the gravitational wave event GW170817 and gamma-ray burst GW170817A, there have been numerous studies constraining the burst properties through analysis of the afterglow light curves.

STATISTICAL PROPERTIES OF GRB AFTERGLOW PARAMETERS AS EVIDENCE OF COSMOLOGICAL EVOLUTION OF THEIR HOST GALAXIES

open access: yesActa Polytechnica, 2014
The results of a study of 43 peaked R-band light curves of optical counterparts of gamma-ray bursts with known redshifts are presented. The parameters of optical transients were calculated in the comoving frame, and then a search for pair correlations ...

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

Electron Signal Induced by GRB 221009A on Charged Particle Telescopes of POES and MetOp Satellites

open access: yesThe Astrophysical Journal, 2023
GRB 221009A is a long gamma-ray burst among the most energetic and nearest ( z = 0.151) detected so far. The energy fluence of the burst was so large to cause ionization of the upper layers of Earth’s atmosphere and also observable signals in satellite ...
