GRBs luminosity function synthesized from \textit{Swift/BAT}, \textit{Fermi/GBM} and \textit{Konus-Wind} data
Hannachi Zitouni, Nidhal Guessoum, Walid Jamel Azzam +1
We study the luminosity function of long gamma-ray bursts (LGRBs) using the peak flux obtained from three LGRB samples with known redshifts: (a) a sample of 251 LGRBs from the \tex…
Prospects for kilonova signals in the gravitational-wave era
Robert Mochkovitch, Frédéric Daigne, Raphaël Duque +1
The binary neutron star merger gravitational-wave signal GW170817 was followed by three electromagnetic counterparts, including a kilonova arising from the radioactivity of freshly…
Detecting the imprint of a kilonova or supernova \\ in short GRB afterglows
Nidhal Guessoum, Hannachi Zitouni, Robert Mochkovitch
Short gamma-ray bursts result from mergers of two neutron stars or from collapsars, but probably at a smaller rate. In the first case, a kilonova occurs while in the second case a…
Distributions of Pseudo-Redshifts and Durations (Observed and Intrinsic) of Fermi GRBs
Hannachi Zitouni, Nidhal Guessoum, Khalid Madjid ALQassimi +1
Ever since the insightful analysis of the durations of GRBs by [Kouveliotou:93], GRBs have most often been classified into two populations: "short bursts" (shorter than 2.0 seconds…
Determination of Cosmological Parameters from Gamma Ray Burst Characteristics and Afterglow Correlations
Hannachi Zitouni, Nidhal Guessoum, Jamil Walid Azzam
We use the correlation relation between the energy emitted by the GRBs in their prompt phases and the X-ray afterglow fluxes, in an effort to constrain cosmological parameters and…
Statistical Study of Observed and Intrinsic Durations among BATSE and Swift/BAT GRBs
Hannachi Zitouni, Nidhal Guessoum, Walid Jamil Azzam +1
Studies of \textit{BATSE} bursts \citep{kouveliotou:93} have resulted in the widespread adoption of a two-group categorization: long bursts (those with durations seconds)…
Revisiting the Amati and Yonetoku Correlations with Swift GRBs
Hannachi Zitouni, Nidhal Guessoum, Walid Jamil Azzam
We use a sample of \textit{Swift} gamma-ray bursts (GRBs) to analyze the Amati and Yonetoku correlations. The first relation is between , the intrinsic peak energy of the…
The GRB luminosity function in the internal shock model confronted to observations
H. Zitouni, F. Daigne, R. Mochkovitch +1
We compute the expected luminosity function of GRBs in the context of the internal shock model. We assume that GRB central engines generate relativistic outflows characterized by t…
