TL;DR: Geological and lunar evidence of radioactive 60Fe implies that at least one supernova exploded within 100 pc of Earth within the last few Myr as mentioned in this paper, and the unique information provided by 60Fe to assess nearby supernovae make now a compelling time for the astronomy community to advocate for supporting multi-disciplinary, crosscutting research programs.
Journal ArticleDOI
Halo star abundances and r-process synthesis
TL;DR: In this paper, the authors review recent observational studies of heavy element abundances in low metallicity stars and explore some implications of these results for nucleosynthesis and early Galactic chemical evolution.
Limits on stellar objects as the dark matter of our halo: nonbaryonic dark matter seems to be required
TL;DR: The nature of the dark matter in the Halo of our Galaxy remains a mystery as mentioned in this paper, and it has been argued that the dark mass does not consist of ordinary stellar or substellar objects.
Journal ArticleDOI
Probing physics beyond the standard model: limits from BBN and the CMB independently and combined
TL;DR: In this article , the authors present new Big Bang Nucleosynthesis (BBN) limits on the cosmic expansion rate or relativistic energy density, quantified via the number Nν of equivalent neutrino species.
Journal ArticleDOI
Probing Primordial and Pre-Galactic Lithium with High-Velocity Clouds
TL;DR: In this paper, the authors proposed a new site for measuring pre-Galactic Li: low-metallicity, high-velocity clouds (HVCs), which are likely to be extragalactic gas accreted onto the Milky Way and which already have been found to have deuterium abundances consistent with primordial.
