The extremely metal-poor stars are the direct descendants of the first generation stars. They carry the chemical signature of the pristine Universe at the time they formed, shortly…
Spectroscopy of the short-hard GRB 130603B: The host galaxy and environment of a compact object merger
A. de Ugarte Postigo, C. C. Thoene, A. Rowlinson +40
Short duration gamma-ray bursts (SGRBs) are thought to be related to the violent merger of compact objects, such as neutron stars or black holes, which makes them promising sources…
Modelling narrow-line regions of active galaxies in the Sloan Digital Sky Survey - I.Sample selection and physical conditions
Zhitai Zhang, Yanchun Liang, François Hammer
We systematically determine the electron density and electron temperature of active galaxies and star-forming galaxies using spectroscopy from the SDSS DR7, while mainly focusing o…
