The R-Process Alliance: Chemo-Dynamically Tagged Groups of Halo $r$-Process-Enhanced Stars Reveal a Shared Chemical-Evolution History

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Dmitrii Gudin, Derek Shank, Timothy C. Beers, Zhen Yuan, Guilherme Limberg | Summary: We derive dynamical parameters for a large sample of 446 $r$-process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the $R$-Process Alliance, supplemented by […]

Observables for Recoil Identification in High-Definition Gas Time Projection Chambers

Posted by klaurent Chicago

Kavli Affiliate: Cosmin Deaconu | First 5 Authors: Majd Ghrear, Sven E. Vahsen, Cosmin Deaconu, , | Summary: Directional detection of nuclear recoils is broadly desirable in nuclear and particle physics. At low recoil energies, this capability may be used to confirm the cosmological origin of a dark matter signal, to penetrate the so-called neutrino […]
