Dynamical Evolution of an Ultra-relativistic Fireball Colliding with a Freely Expanding Gas [PDF]
, 2014 We investigate the hydrodynamical evolution of an ultra-relativistic fireball colliding with a freely expanding gas. The hydrodynamical interaction of the fireball and the gas results in the formation of a geometrically thin shell. We study the dynamical

End-to-end ground calibration and in-flight performance of the FIREBall-2 instrument [PDF]
Journal of Astronomical Telescopes Instruments and Systems, 2020 . The payload of the Faint Intergalactic Redshifted Emission Balloon (FIREBall-2), the second generation of the FIREBall instrument (PI: C. Martin, Caltech), has been calibrated and launched from the NASA Columbia Scientific Balloon Facility in Fort ...

Can a Large Neutron Excess Help Solve the Baryon Loading Problem in Gamma-Ray Burst Fireballs? [PDF]
, 2000 We point out that the baryon-loading problem in Gamma-Ray Burst (GRB) models can be amelioriated if a significant fraction of the baryons which inertially confine the fireball are converted to neutrons.

Coulomb distortion of pi+/pi- as a tool to determine the fireball radius in central high energy heavy ion collisions [PDF]
, 1999 We compute the Coulomb distortion produced by an expanding and highly charged fireball on the spectra of low transverse momenta and mid rapidity pions produced in central high energy heavy ion collisions.

A Cosmological Fireball with 16% Gamma-Ray Radiative Efficiency
The Astrophysical Journal Letters, 2023 Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. How efficiently the jet converts its energy to radiation is a long-standing problem, which is poorly constrained.

Phases of QCD, Thermal Quasiparticles and Dilepton Radiation from a Fireball [PDF]
, 2002 We calculate dilepton production rates from a fireball adapted to the kinematical conditions realized in ultrarelativistic heavy ion collisions over a broad range of beam energies. The freeze-out state of the fireball is fixed by hadronic observables. We

Determining Fireball Fates Using the α–β Criterion [PDF]
Astrophysical Journal, 2019 As fireball networks grow, the number of events observed becomes unfeasible to manage by manual efforts. Reducing and analyzing big data requires automated data pipelines.

, 2020 Two meteorite pieces have been recovered in Italy, near the town of Cavezzo (Modena), on 4 January 2020. The associated fireball was observed on the evening of New Year’s Day 2020 by eight all-sky cameras of the PRISMA fireball network, a partner of ...

, 2020 Accurate knowledge of post-detonation fireball temperatures is important for understanding device performance and for validation of numerical models. Such measurements are difficult to make even under controlled laboratory conditions.

On final conditions in high energy heavy ion collisions [PDF]
, 1998 Motivated by the recent experimental observations, we discuss the freeze-out properties of the fireball created in central heavy ion collisions. We find that the freeze-out conditions, like temperature, velocity gradient near center of the fireball, are ...
