Aims. We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate possible causes of the observed early-time colour variations. Methods. We collected data from various instruments and telescop

Publikováno v: Acta Astronautica. 100:82-93

TechDemoSat-1 is a UK-funded technology demonstration satellite, carrying 8 payloads provided by UK organisations, which is due to be launched in the first quarter of 2014. Cranfield University has supplied a De-Orbit Sail (DOS) payload to allow the

Instrumental Selection Effect on the Bimodal T90 Distribution of Gamma-Ray Bursts

Autor: F. J. Virgili, E. W. Liang, B. Zhang, Y. Qin

Publikováno v: Proceedings of the International Astronomical Union. 8:70-73

The durations (T90) of 315 GRBs detected with Fermi/GBM (8-1000 keV) by 2011 September are calculated using the Bayesian Block method. We compare the T90 distributions between this sample and that observed with previous/current GRB missions. We show

Spectral and temporal analysis of the joint Swift/BAT-Fermi/GBM GRB sample

Autor: En-Wei Liang, Ying Qin, Bing Zhang, Francisco J. Virgili

Publikováno v: Monthly Notices of the Royal Astronomical Society. 424:2821-2831

Using the gamma-ray bursts simultaneously detected by Swift/BAT and Fermi/GBM we performed a joint spectral and temporal analysis of the prompt emission data and confirm the rough correlation between the BAT-band photon index Gamma_BAT and the peak s

Gamma-ray burst rate: high-redshift excess and its possible origins

Autor: Bing Zhang, Jun-Hwan Choi, Kentaro Nagamine, Francisco J. Virgili

Publikováno v: Monthly Notices of the Royal Astronomical Society. 417:3025-3034

Prompted by various analyses of long (Type II) GRB rates and their relationship to the cosmic star-formation history, metallicity and luminosity function evolution, we systematically analyze these effects with a Monte Carlo code. We test various cosm

DISCERNING THE PHYSICAL ORIGINS OF COSMOLOGICAL GAMMA-RAY BURSTS BASED ON MULTIPLE OBSERVATIONAL CRITERIA: THE CASES OFz= 6.7 GRB 080913,z= 8.2 GRB 090423, AND SOME SHORT/HARD GRBs

(Abridged) The two high-redshift gamma-ray bursts, GRB 080913 at z=6.7 and GRB 090423 at z=8.3, recently detected by Swift appear as intrinsically short, hard GRBs. They could have been recognized by BATSE as short/hard GRBs should they have occurred

Low‐Luminosity Gamma‐Ray Bursts as a Unique Population: Luminosity Function, Local Rate, and Beaming Factor

Autor: En-Wei Liang, Francisco J. Virgili, Bing Zhang, Z. G. Dai

Publikováno v: The Astrophysical Journal. 662:1111-1118

Swift/BAT has detected ~ 200 long-duration GRBs, with redshift measurements for ~50 of them. We derive the luminosity function (Phi^{HL}) and the local event rate (rho_0^{HL}) of the conventional high luminosity (HL) GRBs by using the z-known Swift G
