The Late Neogene witnessed various major paleoceanographic changes that culminated in intense Northern Hemisphere Glaciation (NHG). The cause and effects of these changes are still debated. We use a multiproxy approach to determine the relative timing of the closure of the Panama gateway, changes in Atlantic circulation, global cooling and ice sheet growth. Benthic foraminiferal Mg/Ca records f...

We test the hypothesis that observed first-peak (Sr, Y, Zr) and second-peak (Ba) s-process elemental abundances in low-metallicity Milky Way stars, of elements Mo Ru, can be explained by a pervasive r-process contribution originating neutrino-driven winds from highly-magnetic rapidly rotating proto-neutron stars (proto-NSs). construct chemical evolution models incorporate recent calculations pr...
