Strongly coupled Coulomb and nuclear plasma in inner crusts of neutron stars

D. G. Yakovlev, O. Y. Gnedin, A. Y. Potekhin

Matter of subnuclear density in the inner crusts of neutron stars consists of neutron-rich atomic nuclei immersed in strongly degenerate relativistic gas of electrons and strongly…

VLBI imaging of the gravitational lenses B1422+231 and MGJ0414+0534

E. Ros, J. C. Guirado, J. M. Marcaide +5

We present wide-field images of the quadruple gravitational lenses B1422+231 and MGJ0414+0534 obtained from global Very Long Baseline Interferometry (VLBI) observations at 8.4 GHz…

Euler, Hipparcos and the five dwarfs : Reconstructing star formation histories in the Local Group

David Valls-Gabaud, Xavier Hernandez, Gerry Gilmore

The unprecedented quality of recent colour-magnitude diagrams of resolved stellar populations in nearby galaxies requires state-of-the-art techniques to infer the star formation hi…

Detection of Cosmic Shear with the William Herschel Telescope

David Bacon, Alexandre Refregier, Richard Ellis

Gravitational lensing by large-scale structure induces weak coherent alignments in the shapes of background galaxies. Here we present evidence for the detection of this `cosmic she…

A spectroscopic survey for strong galaxy-galaxy lenses

J. P. Willis, P. C. Hewett, S. J. Warren +1

We present a spectroscopic survey for strong galaxy-galaxy lenses. Exploiting optimal sight-lines to massive, bulge-dominated galaxies at redshifts with wide-field, mu…

Low and High Frequency Quasi-Periodic Oscillations in 4U1915-05

L. Boirin, D. Barret, J. F. Olive +2

The X-ray burster and dipper 4U1915-05 (also known as XB1916-053) was observed 19 times for a total exposure of roughly 140 ks between 1996 February and October with the proportion…
