The production of about half of the heavy elements found in nature is assigned to a specific
astrophysical nucleosynthesis process: the rapid neutron-capture process (r process) …

What is the origin of the oxygen we breathe, the hydrogen and oxygen (in form of water
H2O) in rivers and oceans, the carbon in all organic compounds, the silicon in electronic …

Hydrodynamical cosmological simulations are increasing their level of realism by
considering more physical processes and having greater resolution or larger statistics …

After the Big Bang, production of heavy elements in the early Universe takes place starting
from the formation of the first stars, their evolution, and explosion. The first supernova …

Supernova theory, numerical and analytic, has made remarkable progress in the past
decade. This progress was made possible by more sophisticated simulation tools, especially …

We present a detailed report of the connection between long‐duration gamma‐ray bursts
(GRBs) and their accompanying supernovae (SNe). The discussion presented here places …

Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued
evolution of rotating helium stars, M α≳ 10 M⊙, in which iron-core collapse does not …

The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio
wavelengths and the measurement of the redshifts of some of these events, has established …

Gamma-ray bursts (GRB's), short and intense pulses of low-energy γ rays, have fascinated
astronomers and astrophysicists since their unexpected discovery in the late sixties. During …

Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously
with core-collapse supernovae (SNe), thus linking by a common thread nature's two …
