Tuesday - Session 2: First Generation Stars and Galactic Chemical Evolution I
- Weiping Liu (CIAE)
Fluorine is one of the most interesting elements in nuclear astrophysics, where the ${}^{19}\mathrm{F}(p,\alpha){}^{16}\mathrm{O}$ reaction is of crucial importance for Galactic ${}^{19}$F abundances and CNO cycle loss in first generation Population III stars. As a day-one campaign at the Jinping Underground Nuclear Astrophysics experimental facility, we report direct measurements of the...
In addition to the insights gained by studying the galactic evolution of chemical elements, short lived
radioisotopes contain additional information on astrophysical nucleosynthesis sites. Meteorites can
carry information about the nucleosynthetic conditions in the early Solar System using short lived
radioisotopes [1][2], while detections of live isotopes of cosmic origin in the deep sea...
We introduce a user-friendly detailed and modular GALactic Chemical Evolution Model, GalCEM, that tracks isotope masses as a function of time in a given galaxy. The list of tracked isotopes automatically adapts to the complete set provided by the input yields. The present iteration tracks 89 elements broken down into 456 isotopes. We include the following enrichment channels: massive stars...
We present the results of our study of the Luminosity Function of 521 LAEs having a Lya luminosity down to 10^39 erg s−1 with redshift in the range (2.9, 6.7) based on deep observations of 17 clusters obtained with MUSE at the ESO/ VLT. Taking advantage of the magnification effect, this unique data allows us to set strong constraints on the contribution of the LAE population to cosmic...
