Gamma-ray bursters as a research area focuses on the astrophysical study of gamma-ray bursts (GRBs), extremely energetic transient events observed in gamma-ray wavelengths. This field investigates the progenitors (such as massive stellar collapse and compact object mergers), relativistic jet formation, radiation mechanisms (synchrotron, inverse Compton, photospheric emission), and afterglow evolution across the electromagnetic spectrum. Research integrates high-energy astrophysics, relativistic hydrodynamics, nuclear physics, and cosmology, using space-based gamma-ray observatories, rapid follow-up at other wavelengths, and numerical simulations to constrain GRB energetics, beaming, host environments, and their role as probes of star formation, the interstellar/intergalactic medium, and the high-redshift universe.
A Rutgers astrophysicist is helping to solve a cosmic puzzle that has astronomers scratching their heads. The mystery centers on a powerful explosion in space that lasted far longer than anything they have seen before.

Astronomers have conducted multiwavelength observations of a recently detected fast X-ray transient designated EP241107a. Results of the observational campaign, published November 4 on the arXiv preprint server, shed more ...
Considering the immense size of the universe, it's no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen before, and it's challenging ...
On July 2, 2025, NASA's Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours' worth of signals that appeared to come from the same source. When scientists compiled this data with signals picked up by multiple ...
The Search for Extraterrestrial Intelligence (SETI) has a data scale problem. There are just too many places to look for an interstellar signal, and even if you're looking in the right place you could be looking at the wrong ...

Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit over its entire lifetime. ...
A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The gamma-ray bursts from outside the Milky Way galaxy repeated several times over the course of a day. Gamma-ray bursts (GRBs) ...
