Bulk Lorentz factors of Gamma-Ray Bursts [PDF]

open access: yes, 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

On the Bimodal Distribution of Gamma-Ray Bursts [PDF]

open access: yes, 1993
Kouveliotou et al. (1993) recently confirmed that gamma-ray bursts are bimodal in duration. In this paper we compute the statistical properties of the short ($\le 2$~s) and long ($>2$~s) bursts using a method of analysis that makes no assumption regarding the location of the bursts, whether in the Galaxy or at a cosmological distance. We find the 64 ms

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]

open access: yes, 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.

Gamma Ray Bursts [PDF]

open access: yesBerkeley Scientific Journal, 2014
G amma R ay B ursts Bennett Stahl Many strange, incredible and explosive phenomena occur in the vast vacuum of space. Many forces are present in abundance that are more complex and powerful than imaginable; they could destroy life as we know it without leaving a trace of our existence.

Nanoarchitectured transition metal oxides and their composites for supercapacitors

open access: yesElectrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract Supercapacitors have acquired a considerable scientific and technological position in the energy storage field owing to their compelling power capability, good energy density, excellent cycling stability, and ideal safety. The supercapacitor is the burgeoning candidate to cope with the ever‐growing need for green and renewable energy.

Statistical classification of gamma-ray bursts based on the Amati relation [PDF]

open access: yes, 2013
Gamma-ray bursts (GRBs) are believed to belong to two classes and they are conventionally divided according to their durations. This classification scheme is not satisfied due to the fact that duration distributions of the two classes are heavily overlapped.

A Comprehensive Study of the X-ray Bursts from the Magnetar Candidate 1E 2259+586 [PDF]

open access: yesAstrophys.J. 607 (2004) 959-969, 2003
We present a statistical analysis of the X-ray bursts observed from the 2002 June 18 outburst of the Anomalous X-ray Pulsar (AXP) 1E 2259+586, observed with the Proportional Counter Array (PCA) aboard the Rossi X-ray Timing Explorer. We show that the properties of these bursts are similar to those of Soft Gamma-Repeaters (SGRs).

Search for Gravitational Waves Associated with Gamma-Ray Bursts During the First Advanced LIGO Observing Run and Implications for the Origin of GRB 150906B [PDF]

open access: yes, 2016
We present the results of the search for gravitational waves (GWs) associated with $\gamma$-ray bursts detected during the first observing run of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO).
