Open AccessGamma ray burst studies with THESEUS
Gamma-ray Bursts (GRBs) are the most powerful transients in the Universe, over–shining for a few seconds all other γ-ray sky sources. Their emission is produced within narrowly collimated relativistic jets launch...

Open AccessExploration of the high-redshift universe enabled by THESEUS
At peak, long-duration gamma-ray bursts are the most luminous sources of electromagnetic radiation known. Since their progenitors are massive stars, they provide a tracer of star formation and star-forming gal...

A Comprehensive Analysis of Polarized \(\gamma \) -ray Beam Data with the HARPO Demonstrator
We investigate the feasibility of gaseous TPC as a telescope and a polarimeter for cosmic gamma-rays, focussing on the energy range from 1 to 100 MeV. Our beam results show the angular resolution can reach a f...

Circular polarization in the optical afterglow of GRB 121024A
Circularly polarized light is unexpectedly detected in the afterglow of γ-ray burst GRB 121024A measured 0.15 days after the burst, and is shown to be intrinsic to the afterglow and unlikely to be produced by ...

Effect of prostaglandin E2 on ACTH and β-endorphin release from rat adenohypophysis in vitro after secretagogues which can mimic various first or second messengers
The purpose of the present study was to further characterize the inhibition by prostaglandin E2 (PGE2) of adrenocorticotropin (ACTH) and β-endorphin release from rat anterior pituitary fragments in vitro. Peptide...
