The Most Metal-Poor Stars. IV. The Two Populations With [Fe/H] [< over ~] -3.0 by Frebel, Anna L., Norris, John E., Yong, David, Bessell, M. S., Christlieb, N., Asplund, M., Gilmore, Gerard, Wyse, Rosemary F. G., Beers, Timothy C., Barklem, P. S., Ryan, S. G.

The thallium isotope composition of carbonaceous chondrites - New evidence for live ²⁰⁵Pb in the early solar system by Baker, R, Schönbächler, M, Rehkämper, M, Williams, H, Halliday, A

“…The extinct radionuclide ²⁰⁵Pb, which decays to ²⁰⁵Tl with a half-life of 15 Ma, is of considerable cosmochemical interest, as it is the only short-lived isotope that is produced exclusively by s-process nucleosynthesis. Evidence for the existence of ²⁰⁵Pb in the early solar system has only recently been obtained from analyses of IAB iron meteorites, but significant uncertainties remain about the initial ²⁰⁵Pb abundance and Tl isotope composition of the solar system. …”

The thallium isotope composition of carbonaceous chondrites - New evidence for live Pb-205 in the early solar system by Baker, R, Schonbachler, M, Rehkamper, M, Williams, H, Halliday, A

“…The extinct radionuclide 205Pb, which decays to 205Tl with a half-life of 15 Ma, is of considerable cosmochemical interest, as it is the only short-lived isotope that is produced exclusively by s-process nucleosynthesis. Evidence for the existence of 205Pb in the early solar system has only recently been obtained from analyses of IAB iron meteorites, but significant uncertainties remain about the initial 205Pb abundance and Tl isotope composition of the solar system. …”

Cosmological consequences of supersymmetric flat directions by Riva, F

“…This is in conflict with the upper bound on the reheating temperature which is found by imposing that the gravitinos generated during the reheating stage after inflation do not jeopardize successful nucleosynthesis. We show that a solution to this tension is actually already incorporated in the framework, because of the presence of flat directions in the supersymmetric scalar potential. …”

Evidence of the accelerated expansion of the Universe from weak lensing tomography with COSMOS by Schrabback, T, Hartlap, J, Joachimi, B, Kilbinger, M, Simon, P, Benabed, K, Bradač, M, Eifler, T, Erben, T, Fassnacht, C, High, F, Hilbert, S, Hildebrandt, H, Hoekstra, H, Kuijken, K, Marshall, P, Mellier, Y, Morganson, E, Schneider, P, Semboloni, E, Van Waerbeke, L, Velander, M

“…Dropping the assumption of flatness and using priors from the HST Key Project and Big-Bang nucleosynthesis only, we find a negative deceleration parameter q0 at 94.3% confidence from the tomographic lensing analysis, providing independent evidence of the accelerated expansion of the Universe. …”

The s-process in the Nd-Pm-Sm region: Neutron activation of 147Pm by C. Guerrero, M. Tessler, M. Paul, J. Lerendegui-Marco, S. Heinitz, E.A. Maugeri, C. Domingo-Pardo, R. Dressler, S. Halfon, N. Kivel, U. Köster, T. Palchan-Hazan, J.M. Quesada, D. Schumann, L. Weissman

“…These values are 41% higher (to the ground state) and 15% lower (to the metastable state) than the values reported so far, leading however to a total cross section of 826(107) mb consistent within uncertainties with the previous result and hence leaving unchanged the previous calculation of the s-process neutron density. Keywords: Nucleosynthesis, Neutron capture, Nuclear reactions, s-process, MACS, Neutron activation…”
