Gamma-Ray Burst Energetics [PDF]

The Astrophysical Journal, 1999
We estimate the fraction of the total energy in a Gamma-Ray Burst (GRB) that is radiated in photons during the main burst. Random internal collisions among different shells limit the efficiency for converting bulk kinetic energy to photons. About 1% of the energy of explosion is converted to radiation, in 10-1000 kev energy band in the observer frame ...

Anionic Citrate‐Based 3D‐Printed Scaffolds for Tunable and Sustained Orthobiologic Delivery to Enhance Tissue Regeneration

Advanced Functional Materials, EarlyView.
A potent anionic citric acid‐based 3D‐printed scaffold is developed for the sustained and controlled release of orthobiologics to enhance orthopedic therapeutic efficacy. Comprehensive in vivo studies demonstrated effective bone fusion and high safety at a low dose of BMP‐2 delivered by the system, establishing it as a promising platform for safe ...

Limits on Fast Radio Burst–like Counterparts to Gamma-Ray Bursts Using CHIME/FRB

The Astrophysical Journal, 2023
Fast radio bursts (FRBs) are a class of highly energetic, mostly extragalactic radio transients lasting for ∼milliseconds. While over 600 FRBs have been published so far, their origins are presently unclear, with some theories for extragalactic FRBs ...

The impact of star formation and gamma-ray burst rates at high redshift on cosmic chemical evolution and reionization [PDF]

, 2014
Recent observations in the total luminosity density have led to significant progress in establishing the star formation rate (SFR) at high redshift. Concurrently observed gamma-ray burst rates have also been used to extract the SFR at high redshift.

LOCALIZATION OF GAMMA-RAY BURSTS USING THE FERMI GAMMA-RAY BURST MONITOR [PDF]

, 2014
The Fermi Gamma-ray Burst Monitor (GBM) has detected over 1400 gamma-ray bursts (GRBs) since it began science operations in 2008 July. We use a subset of over 300 GRBs localized by instruments such as Swift, the Fermi Large Area Telescope, INTEGRAL, and ...

The x-/gamma-ray camera ECLAIRs for the gamma-ray burst mission SVOM [PDF]

Astronomical Telescopes and Instrumentation, 2014
We present ECLAIRs, the Gamma-ray burst (GRB) trigger camera to fly on-board the Chinese-French mission SVOM. ECLAIRs is a wide-field (~ 2 sr) coded mask camera with a mask transparency of 40% and a 1024 cm2 detection plane coupled to a data processing ...

Gamma-ray Bursts and Afterglow [PDF]

Symposium - International Astronomical Union, 2000
The origin of GRBs has been a mystery for almost 30 years. Their sources emit a huge amount of energy on short time scales, and the process involves extreme relativistic motion with a bulk Lorentz factor of at least a few hundred. In the last two years, “afterglow” emission in X-ray, optical, IR, and radio was detected. The afterglow can be measured up

VLBI and Archival VLA and WSRT Observations of the GRB 030329 Radio Afterglow

, 2012
We present VLBI and archival Karl G. Jansky Very Large Array (VLA) and Westerbork Synthesis Radio Telescope (WSRT) observations of the radio afterglow from the gamma-ray burst (GRB) of 2003 March 29 (GRB 030329) taken between 672 and 2032 days after the ...
