We present an interpretation of the phenomenological relations between the spectral peak, isotropic luminosity, and duration of long gamma-ray bursts that have been discovered by Amati and coworkers, Ghirlanda and coworkers, Firmani and coworkers, and Liang & Zhang. In our proposed model, a jet undergoes internal dissipation which prevents its bulk Lorentz factor from exceeding 1/θ (θ being the jet opening angle) until it escapes from the core of its progenitor star, at a radius of order 1010… 
NON-THERMAL EMISSION FROM THE PHOTOSPHERES OF GAMMA-RAY BURST OUTFLOWS. I. HIGH-FREQUENCY TAILS
We study the spectrum of high-frequency radiation emerging from mildly dissipative photospheres of long-duration gamma-ray burst outflows. Building on the results of recent numerical investigations,
On thermalization in gamma-ray burst jets and the peak energies of photospheric spectra
The low-energy spectral slopes of the prompt emission of most gamma-ray bursts (GRBs) are difficult to reconcile with radiatively efficient optically thin emission models irrespective of the
Photospheric Emission in Gamma-Ray Bursts
A major breakthrough in our understanding of gamma-ray bursts (GRB) prompt emission physics occurred in the last few years, with the realization that a thermal component accompanies the over-all
The emission mechanism in magnetically dominated gamma-ray burst outflows
We consider the conditions within a Gamma-Ray Burst (GRB) emission region that is Poynting flux dominated. Due to the enormous magnetic energy density, relativistic electrons will cool in such a
Variable jet properties in GRB 110721A: time resolved observations of the jet photosphere
Fermi Gamma-ray Space Telescope observations of GRB110721A have revealed two emission components from the relativistic jet: emission from the photosphere, peaking at 100 keV and a non-thermal
TRANSPARENCY PARAMETERS FROM RELATIVISTICALLY EXPANDING OUTFLOWS
In many gamma-ray bursts a distinct blackbody spectral component is present, which is attributed to the emission from the photosphere of a relativistically expanding plasma. The properties of this
The Low-Energy Spectral Index of Gamma-ray Burst Prompt Emission from Internal Shocks
The prompt emission of most gamma-ray bursts (GRBs) typically exhibits a non-thermal Band component. The synchrotron radiation in the popular internal shock model is generally put forward to explain

TLDR
The interpretation that the peak in the photon spectrum can be attributed to the black-body emission of the photosphere of the outflow, having a temperature of approximately 109 K is presented.
PROMPT TeV NEUTRINOS FROM THE DISSIPATIVE PHOTOSPHERES OF GAMMA-RAY BURSTS
Recently it was suggested that a photospheric component that results from internal dissipation occurring in the optically thick inner parts of relativistic outflows may be present in the prompt

The emission mechanism of gamma-ray bursts (GRBs) is still a matter of debate. The standard synchrotron energy spectrum of cooling electrons F E E -1/2 is much too soft to account for the majority of
