Characteristics of flux-time profiles, temporal evolution, and spatial distribution of radiation-belt electron precipitation bursts in the upper ionosphere before great and giant earthquakes
Earthquake precursors particle precipitation wave particle interactions
2015/8/24
The analysis of energetic electron observations made by the DEMETER satellite reveals that radiation belt electron precipitation (RBEP) bursts are observed in general several (~1-6 days) before a larg...
Can Sequentially Linked Gamma-Ray Bursts Nullify Randomness?
Gamma-Ray Bursts Nullify Randomness General Physics
2012/5/17
In order to nullify the property of randomness perceived in the dispersion of gamma-ray bursts (GRB's) we introduce two new procedures. 1. Create a segmented group of sequentially linked GRB's and qua...
Optimum Drift Velocity for Single Molecule Fluorescence Bursts in Micro/Nano-Fluidic Channels
Optimum Drift Velocity Single Molecule Fluorescence Micro/Nano-Fluidic Channels Instrumentation and Detectors
2012/4/24
Photonic burst histograms can be used to identify single protein molecules in micro/nano-fluidic channels provided the width of the histogram is narrow. Photonic shot noise and residence time fluctuat...
Thermonuclear X-ray bursts from the 401 Hertz accreting pulsar IGR J17498-2921: indication of burning in confined regions
Thermonuclear X-ray bursts pulsar IGR J17498-2921 indication confined regions
2012/2/23
We use the 2011 Rossi X-ray Timing Explorer (RXTE) proportional counter array (PCA) data of the 401 Hz accreting pulsar and burster IGR J17498-2921 to perform timing analysis and time-resolved spectro...
Spectral-Temporal Simulations of Internal Dissipation Models of Gamma-Ray Bursts
Spectral-Temporal Simulations Internal Dissipation Models Gamma-Ray Bursts
2011/10/19
We present calculations of the time evolution of the prompt spectra of gamma-ray burst models involving generic internal dissipation regions, including internal shocks, either by itself or in the pres...
The Galactic dust-to-metals ratio and metallicity using gamma-ray bursts
Gamma-ray burst: general – ISM: abundances – dust, extinction – Galaxy: abundances – X-rays: ISM
2011/10/18
The metallicity and dust-to-metals ratio of the Galaxy are fundamental parameters in understanding the ISM, but there is still uncertainty surrounding these parameters. In this paper, the dust-to-meta...
The Role of Stochastic Re-acceleration in the Prompt Emission of Gamma-Ray Bursts: Application to Hadronic Injection
Stochastic Re-acceleration Prompt Emission Gamma-Ray Bursts: Application Hadronic Injection
2011/10/20
We study effects of particle re-acceleration in the post-shock region via magnetohydrodynamic/plasma turbulence, in the context of a mixed hadronic-leptonic model for the prompt emission of gamma-ray ...
Systematics in Aggregated Neutrino Fluxes and Flavor Ratios from Gamma-Ray Bursts
Systematics Aggregated Neutrino Fluxes Flavor Ratios Gamma-Ray Bursts
2011/10/20
Gamma-ray burst analyses at neutrino telescopes are typically based on diffuse or stacked (i.e., aggregated) neutrino fluxes, because the number of events expected from a single burst is small. The ag...
In the internal shock model of gamma ray bursts ultrahigh energy pions, kaons and neutrons are likely to be produced in the interactions of shock accelerated relativistic protons with low energy photo...
Lognormal Distribution of Single Molecule Fluorescence Bursts in Micro/Nano-Fluidic Channels
Lognormal Distribution Single Molecule Fluorescence Burst Micro/Nano-Fluidic Channels
2011/8/5
Abstract: The width and shape of photon burst histograms pose significant limitations to the identification of single molecules in micro/nano-fluidic channels, and the nature of these histograms is no...
Gamma Ray Bursts in the comoving frame
Gamma-ray: bursts— Radiation mechanisms: non thermal
2011/10/12
We estimate the bulk Lorentz factor Gamma_0 of 32 GRBs using the measured peak time of their afterglow light curves. We consider two possible scenarios for the estimate of Gamma_0: the case of a homog...
In 2004, SGR 1806-20 underwent a period of intense and long-lasting burst activity that included the giant flare of 27 December 2004 -- the most intense extra-solar transient event ever detected at Ea...
Short Gamma-ray Bursts: the mass of the accretion disk and the initial radius of the outflow
Short Gamma-ray Bursts:accretion disk initial radius outflow
2011/10/9
In this work we estimate the accretion-disk mass in the specific scenario of binary-neutron-star-merger with current observational data. Assuming that the outflows of short Gamma-ray Bursts (GRBs) are...
We present our temporal and spectral analyses of 29 bursts from SGR J0501+4516, detected with the Gamma-ray Burst Monitor onboard the Fermi Gamma-ray Space Telescope during the 13 days of the source a...

2011/9/30
We present the first systematic study of X-ray flare candidates in short gamma-ray bursts (SGRBs) exploiting the large 6-year Swift database with the aim to constrain the physical nature of such fluct...
