It is believed that the relativistic jets of gamma-ray bursts (GRBs) should initially propagate through a heavy envelope of the massive progenitor stars or through a merger ejecta formed from the compact binary mergers. The interaction of a jet with a stellar envelope or a merger ejecta can lead to the deceleration of the head material of the jet and simultaneously the formation of a hot cocoon. However, this jet-envelope/ejecta interaction is actually undetectable with electromagnetic…

Neutron Star Mergers in Active Galactic Nucleus Accretion Disks: Cocoon and Ejecta Shock Breakouts
Neutron star mergers are believed to occur in accretion disks around supermassive black holes. Here we show that a putative jet launched from the merger of a binary neutron star (BNS) or a neutron
High-energy Neutrinos from Choked Gamma-Ray Bursts in Active Galactic Nucleus Accretion Disks
Both long-duration gamma-ray bursts (LGRBs) from the core collapse of massive stars and short-duration GRBs (SGRBs) from mergers of a binary neutron star or a neutron star–black hole are expected to

We are proposing Gravitational-wave Lunar Observatory for Cosmology (GLOC) [1] – a first of its kind fundamental physics experiment on the surface of the Moon. The experiment would access
The Jet Structure and the Intrinsic Luminosity Function of Short Gamma-Ray Bursts
The joint observation of GW170817 and GRB 170817A indicated that short gamma-ray bursts (SGRBs) can originate from binary neutron star mergers. Moreover, some SGRBs could be detected off-axis, while


Jet Collimation in the Ejecta of Double Neutron Star Mergers: A New Canonical Picture of Short Gamma-Ray Bursts
The observations of jet breaks in the afterglows of short gamma-ray bursts (SGRBs) indicate that the jet has a small opening angle of 10°. The collimation mechanism of the jet is a longstanding
Can an Off-axis Gamma-Ray Burst Jet in GW170817 Explain All the Electromagnetic Counterparts?.
Gravitational waves from a merger of two neutron stars (NSs) were discovered for the first time in GW170817, together with diverse electromagnetic (EM) counterparts. To make constraints on a
The X-ray counterpart to the gravitational-wave event GW170817
The detection of X-ray emission at a location coincident with the kilonova transient provides the missing observational link between short γ-ray bursts and gravitational waves from neutron-star mergers, and gives independent confirmation of the collimated nature of the γ,ray-burst emission.
Supernova hosts for gamma-ray burst jets: dynamical constraints
I constrain a possible supernova origin for gamma-ray bursts (GRBs) by modelling the dynamical interaction between a relativistic jet and a stellar envelope surrounding it. The delay in observer time
Gravitational-Wave Memory from the Relativistic Jet of Gamma-Ray Bursts
The gravitational-wave (GW) memory from a radiating and decelerating point mass is studied in detail. It is found that for isotropic photon emission the memory generated from the photons is
The dynamics of a highly magnetized jet propagating inside a star
The collapsar model explains the association of long duration gamma-ray bursts (GRBs) with stellar collapse. It involves a relativistic jet that forms at the core of a collapsing massive star. The
A mildly relativistic wide-angle outflow in the neutron-star merger event GW170817
The cocoon model explains the radio light curve of GW170817, as well as the γ-ray and X-ray emission (and possibly also the ultraviolet and optical emission), and is the model that is most consistent with the observational data.
Relativistic MHD simulations of core-collapse GRB jets: 3D instabilities and magnetic dissipation
Relativistic jets naturally occur in astrophysical systems that involve accretion onto compact objects, such as core collapse of massive stars in gamma-ray bursts (GRBs) and accretion onto
Gravitational wave memory from gamma ray bursts’ jets
While the possible roles of gamma ray bursts' (GRBs) progenitors as gravitational waves (GW) sources have been extensively studied, little attention has been given to the GRB jet itself as a GW
Late Time Afterglow Observations Reveal a Collimated Relativistic Jet in the Ejecta of the Binary Neutron Star Merger GW170817.
It is shown that structured jets with a relativistic, energetic core surrounded by slower and less energetic wings produce afterglow emission that brightens characteristically with time, as recently seen in the after glow of GW170817.
