1507.07932 | we investigate the change in ionizing photons in galaxies between @xmath0 using the f2 field of the shels complete galaxy redshift survey . we show , for the first time , that while the [ ] /h@xmath1 and [ ] / [ ] ratios rise , the [ ] /h@xmath2 and [ ] /h@xmath2 ratios fall significantly over the @xmath3 redshift rang... | 213 |
1301.5616 | gravitational - wave observations of compact binaries have the potential to uncover the distribution of masses and spins of black holes and neutron stars in the universe . the binary components physical parameters can be inferred from their effect on the phasing of the gravitational - wave signal , but a partial degene... | 245 |
