Cosmology with gamma-ray bursts
Astronomical and Astrophysical Transactions, 2022 Gamma-ray bursts constitute one of the most fascinating and relevant phenomena in modern science, with strong implications for several fields of astrophysics, cosmology and fundamental physics. In this short review, I focus on the prospective key-role of GRBs for cosmology. Indeed, the huge luminosity, the redshift distribution extending at least up

Evidence for anisotropy in the distribution of short-lived gamma-ray bursts [PDF]
, 2003 Measurements of the two-point angular correlation function w(\theta) for 407 short gamma-ray bursts collected in the Current BATSE Catalogue reveal a ~2 \sigma deviation from isotropy on angular scales \theta ~ 2-4 degrees.

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,

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

Advanced Healthcare Materials, EarlyView.The limitations of existing clinical treatments highlight the need for a more comprehensive strategy for addressing infected diabetic wounds. A tri‐layered scaffold is developed to deliver therapeutics loaded in CuBDC and ZIF‐8 MOFs that are tailored to the requirements of deep‐infected diabetic wounds.

GRB-SN Association within the Binary-driven Hypernova Model
The Astrophysical Journal, 2023 Observations of supernovae (SNe) Ic occurring after the prompt emission of long gamma-ray bursts (GRBs) are addressed within the binary-driven hypernova (BdHN) model where GRBs originate from a binary composed of a ∼10 M _⊙ carbon–oxygen (CO) star and a ...

The rate and luminosity function of long Gamma Ray Bursts [PDF]
, 2015 We derive, adopting a direct method, the luminosity function and the formation rate of long Gamma Ray Bursts through a complete, flux-limited, sample of Swift bursts which has a high level of completeness in redshift z (~82%). We parametrise the redshift

The origin of the optical flashes: The case study of GRB 080319B and GRB 130427A [PDF]
, 2018 Correlations between optical flashes and gamma-ray emissions in gamma-ray bursts have been searched in order to clarify the question whether these emissions occur at internal and/or external shocks.
