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) …

We develop a hybrid model of galactic chemical evolution that combines a multiring
computation of chemical enrichment with a prescription for stellar migration and the vertical …

The distribution of elements in galaxies provides a wealth of information about their
production sites and their subsequent mixing into the interstellar medium. Here we …

Live (not decayed) radioisotopes on the Earth and Moon are messengers from recent
nearby astrophysical explosions. Measurements of 60Fe in deep-sea samples, Antarctic …

We present the discovery of the X-ray and optical afterglows of the short-duration GRB
150101B, pinpointing the event to an early-type host galaxy at z= 0.1343±0.0030. This …

The distributions of a galaxy's gas and stars in chemical space encode a tremendous
amount of information about that galaxy's physical properties and assembly history …

Aims. Various nucleosynthesis studies have pointed out that the r-process elements in very
metal-poor (VMP) halo stars might have different origins. By means of familiar concepts from …

The recent detection of the live isotopes 60 Fe and 244 Pu in deep ocean sediments dating
back to the past 3–4 Myr poses a serious challenge to the identification of their production …

Binary neutron star mergers produce high-energy emissions from several physically different
sources, including a gamma-ray burst (GRB) and its afterglow, a kilonova (KN), and, at late …

The discovery of a binary neutron star merger (NSM) through both its gravitational wave and
electromagnetic emission has revealed these events to be key sites of r-process …
