This article addresses three of the four nucleosynthesis processes involved in producing
heavy nuclei beyond Fe (with a main focus on the r-process). Opposite to the fourth process …

The production of elements by rapid neutron capture (r-process) in neutron-star mergers is
expected theoretically and is supported by multimessenger observations,–of gravitational …

Although there is strong support for the collapsar engine as the power source of long‐
duration gamma‐ray bursts (GRBs), we still do not definitively know the progenitor of these …

It is now accepted that long-duration γ-ray bursts (GRBs) are produced during the collapse
of a massive star1, 2. The standard 'collapsar'model3 predicts that a broad-lined and …

We have gathered optical photometry data from the literature on a large sample of Swift-era
gamma-ray burst (GRB) afterglows including GRBs up to 2009 September, for a total of 76 …

Well before the afterglow era, Paczynski (1986) noted that “cosmological” distances of GRBs
would imply that the energy release in gamma rays would be comparable to the energy …

Gamma-ray bursts (GRBs) have been separated into two classes, originally along the lines
of duration and spectral properties, called" short/hard" and" long/soft." The latter have been …

We perform hydrodynamic and nucleosynthesis calculations of core-collapse supernovae
(SNe) and hypernovae (HNe) of Population (Pop) III stars. We provide new yields for the …

ABSTRACT Two-dimensional (2D) hydrodynamical simulations of progenitor evolution of a
23 M☉ star, close to core collapse (in∼ 1 hr in one dimension (1D)), with simultaneously …

The delay time distribution of neutron star mergers provides critical insights into binary
evolution processes and the merger rate evolution of compact object binaries. However …
