Messages from GRB 060218

How the broadband data pose strong constraints on possible models of the prompt emission of this GRB is discussed, and it is suggested that X-ray flashes (XRFs) are natural extension of GRBs in the softer regime and that GRBs and XRFs share the same radiation physics.

Prompt emission of high‐energy photons from gamma ray bursts

Within the internal shock scenario, we consider different mechanisms of high-energy ( > 1 MeV) photon production inside a gamma ray burst (GRB ) fireball and derive the expected high-energy photon

Exploring the Properties of Choked Gamma-ray Bursts with IceCube’s High-energy Neutrinos

Long duration gamma-ray bursts (GRBs) have often been considered the natural evolution of some core-collapse supernova (CCSN) progenitors. However, the fraction of CCSNe linked to astrophysical jets

Very High Energy Neutrinos from nearby long GRB Afterglows

Long duration Gamma Ray Bursts (GRBs) are well-motivated sources of Ultra High Energy Cosmic Rays (UHECRs) and neutrinos. During the afterglow phase these particles can be produced as a result of

Low-luminosity gamma-ray bursts as the sources of ultrahigh-energy cosmic ray nuclei

Recent results from the Pierre Auger Collaboration have shown that the composition of ultrahigh-energy cosmic rays (UHECRs) becomes gradually heavier with increasing energy. Although gamma-ray bursts

Constraining the contribution of Gamma-Ray Bursts to the high-energy diffuse neutrino flux with 10 years of ANTARES data

Gamma-Ray Bursts (GRBs) are considered very interesting astrophysical sources to be studied in the context of neutrino astronomy. Indeed, their jet composition continues to be an open issue. Within

Cumulative Neutrino and Gamma-Ray Backgrounds from Halo and Galaxy Mergers

The merger of dark matter halos and the gaseous structures embedded in them, such as protogalaxies, galaxies, and groups and clusters of galaxies, results in strong shocks that are capable of


Star-forming and starburst galaxies are considered one of the viable candidate sources of the high-energy cosmic neutrino background detected in IceCube. We revisit contributions of supernova

Neutrino emission from a gamma-ray burst afterglow shock during an inner supernova shock breakout

The observations of a nearby low-luminosity gamma-ray burst (GRB) 060218 associated with supernova SN 2006aj may imply an interesting astronomical picture where a supernova shock breakout locates

Multi-messenger Light Curves from Gamma-Ray Bursts in the Internal Shock Model

Gamma-ray bursts (GRBs) are promising as sources of neutrinos and cosmic rays. In the internal shock scenario, blobs of plasma emitted from a central engine collide within a relativistic jet and form



Luminosity Function of Gamma-Ray Bursts Derived without Benefit of Redshifts

We show that the Euclidean value of for gamma-ray bursts (GRBs) selected on a timescale of 1024 ms is correlated with spectral hardness. The value of ranges from ~0.42 for soft bursts to ~0.26 for

Neutrino Afterglows and Progenitors of Gamma-Ray Bursts

Currently popular models for progenitors of gamma-ray bursts (GRBs) are the mergers of compact objects and the explosions of massive stars. These two cases have distinctive environments for GRBs:

Prompt Gamma-Ray Burst Spectra: Detailed Calculations and the Effect of Pair Production

We present detailed calculations of the prompt spectrum of γ-ray bursts (GRBs) predicted within the fireball model framework, in which emission is due to internal shocks in an expanding relativistic

An unusual supernova in the error box of the γ-ray burst of 25 April 1998

The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio wavelengths and the measurement of the redshifts of some of these events, has established that γ-ray bursts lie at

Radio emission from the unusual supernova 1998bw and its association with the γ-ray burst of 25 April 1998

Data accumulated over the past year strongly favour the idea that γ-ray bursts lie at cosmological distances, although the nature of the power source remains unclear. Here we report radio

High-energy neutrinos from gamma ray bursts.

Detailed calculations of photomeson neutrino production are presented for the collapsar model, where internal nonthermal synchrotron radiation is the primary target photon field, and the supranova model,where external pulsar-wind synch rotary radiation provides important additional target photons.

Intrinsic spectra and energetics of BeppoSAX Gamma-Ray Bursts with known redshifts

We present the main results of a study of spectral and energetics properties of twelve gamma-ray bursts (GRBs) with redshift estimates. All GRBs in our sample were detected by BeppoSAX in a broad

Neutrino signatures of the supernova - gamma-ray burst relationship

We calculate the TeV-PeV neutrino fluxes of gamma-ray bursts associated with supernovae, based on the observed association between GRB 030329 and supernova SN 2003dh. The neutrino spectral flux
