The Pristine Survey is a narrow-band photometric survey focused on the
metallicity-sensitive Ca H & K lines and conducted in the northern hemisphere
with the wide-field MegaCam on the Canada-France-Hawaii Telescope. The
main aims of the survey are to uncover a statistical sample of the most
metal-poor stars in the Galaxy, to further characterize the smallest
Milky Way satellites, and to...

We perform cosmological zoom-in simulations with the goal of studying the energy and statistics of the neutron star mergers in order to explain the
high observed abundances of R-process elements in local ultra faint dwarf (UFD) galaxies. We model our star formation in a stochastic fashion in order to resolve the stellar
mass content the UFDs. We perform zoom simulations on two different...

We computed the fission properties of nuclei in the range $84 \le Z \le 120$ and $118 \le N \le 250$ using the Barcelona-Catania-Paris-Madrid (BCPM) Energy Density Functional (EDF). For the first time a set
of spontaneous and neutron-induced fission rates were obtained from a microscopic calculation of nuclear collective inertias. These fission rates were used as a nuclear input in the...

Beta-decay properties are important nuclear input for r-process calculations. A large number of experiments focus on the measurement of beta-decay half-lives and neutron emission probabilities. A new effort has started at the NSCL to go beyond measuring these integral quantities and investigate further the details of the beta-decay intensity distribution for r-process nuclei. This...

The r-process is one of the fundamental ways that stars produce heavy elements. For decades, a major challenge has been an inability to produce compelling observations that directly link the r-process with an astrophysical site. In early 2016, two groups independently confirmed the existence of a dwarf galaxy, called Reticulum II, where most of the stars are highly enhanced in r-process...
