0710.1032 | we discuss the link between dark matter halos hosting the first popiii stars formed at redshift @xmath0 and the rare , massive , halos that are generally considered to host bright @xmath1 quasars . we show that within the typical volume occupied by one bright high - z qso the remnants of the first several thousands pop... | 202 |
1303.1612 | as we go from center toward the surface of a neutron star , the state of baryonic matter changes from the de - confined quark - gluon to a mixed phase of quark and hadronic matter , and a thin crust of hadronic matter . for the quark matter , within mit bag model , the total energy density of the system is the kinetic ... | 192 |
1602.07300 | inequality and its consequences are the subject of intense recent debate . using a simplified model of the economy , we address the relation between inequality and liquidity , the latter understood as the frequency of economic exchanges . assuming a pareto distribution of wealth for the agents , that is consistent with... | 113 |
1410.7929 | we present a study of the kinematics of the remote globular cluster ngc 5694 based on giraffe@vlt medium resolution spectra . a sample of 165 individual stars selected to lie on the red giant branch in the cluster color magnitude diagram was considered . using radial velocity and metallicity from calcium triplet , we w... | 236 |
