Gamma-Ray Bursts [PDF]

open access: yesScience, 2012
Stellar Explosions Stars that are born with masses greater than eight times that of the Sun end their lives in luminous explosions known as supernovae. Over the past decade, access to improved sky surveys has revealed rare types of supernovae that are much more luminous than any of those that were known before.

ON GAMMA-RAY BURSTS [PDF]

open access: yesThe Eleventh Marcel Grossmann Meeting, 2008
(Shortened) We show by example how the uncoding of Gamma-Ray Bursts (GRBs) offers unprecedented possibilities to foster new knowledge in fundamental physics and in astrophysics. After recalling some of the classic work on vacuum polarization in uniform electric fields by Klein, Sauter, Heisenberg, Euler and Schwinger, we summarize some of the efforts ...

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

open access: yesThe Astrophysical Journal Supplement Series, 2015
The Fermi Gamma-ray Burst Monitor (GBM) has detected over 1400 Gamma-Ray Bursts (GRBs) since it began science operations in July, 2008. We use a subset of over 300 GRBs localized by instruments such as Swift, the Fermi Large Area Telescope, INTEGRAL, and MAXI, or through triangulations from the InterPlanetary Network (IPN), to analyze the accuracy of ...

Gamma-ray bursts [PDF]

open access: yesReports on Progress in Physics, 2006
Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and mechanism are the focus of intense research and debate. More than three decades after their discovery, and after pioneering breakthroughs from space and ground experiments, their study is entering a new phase with the recently launched Swift satellite. The interplay

Superlong gamma-ray bursts [PDF]

open access: yesAstronomy Letters, 2005
Before the BATSE/GRO launch GRBs seem to be a uniform phenomenon with duration up to about 100 seconds. The BATSE has detected many events longer than 100 s and a few longer than 500s. We performed the off-line scan of the 1024 ms continuous BATSE records and revealed several non-triggered episodes of the BATSE GRB triggers which confidently belong to ...

THE COSMIC GAMMA-RAY BURSTS [PDF]

open access: yesThe Ninth Marcel Grossmann Meeting, 2002
Cosmic gamma-ray bursts are one of the great frontiers of astrophysics today. They are a playground of relativists and observers alike. They may teach us about the death of stars and the birth of black holes, the physics in extreme conditions, and help us probe star formation in the distant and obscured universe. In this review we summarise some of the

Search for Gravitational-wave Signals Associated with Gamma-Ray Bursts during the Second Observing Run of Advanced LIGO and Advanced Virgo

open access: yesThe Astrophysical Journal, 2019
We present the results of targeted searches for gravitational-wave transients associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo, which took place from 2016 November to 2017 August.

Afterglow Polarization from Off-axis Gamma-Ray Burst Jets

open access: yesThe Astrophysical Journal, 2023
As we further our studies on gamma-ray bursts (GRBs), via both theoretical models and observational tools, more and more options begin to open for exploration of its physical properties.

Supernovae and Gamma-Ray Bursts [PDF]

open access: yesChinese Journal of Astronomy and Astrophysics, 2006
I review the observational status of the Supernova/Gamma-Ray Burst (GRB) connection. Available data suggest that Supernovae (SNe) associated with GRBs form an heterogeneous class of objects including bright and faint hypernovae (Hyp) and perhaps also `standard' Ib/c events.
