Microlensing is at its golden age. It has a specific niche to address scientific questions that can only be answered by this approach. The different consortium involved in the ground base studies have evolved from competitive teams, to a global worl…

Space based microlensing planet searches

The discovery of extra-solar planets is arguably the most exciting development in astrophysics during the past 15 years, rivalled only by the detecti…

The spin-weighted spherical harmonic modes of the polarization waveforms at 3PN order can now be obtained from using the angular integration (5). An alternative route would be to use the relations (6)–(7) giving the modes directly in terms of separa…

The third post-Newtonian gravitational wave polarisations and associa…

The gravitational waveform (GWF) generated by inspiralling compact binaries moving in quasi-circular orbits is computed at the third post-Newtonian (…

Building on previous work (Ref. Marsat et al. (2012), referred to as Paper I) we have presented complete results valid at the next-to-next-to-leading order, corresponding to 3.5PN order, for the spin-orbit contributions to the dynamics of spinning c…

Next-to-next-to-leading order spin-orbit effects in the near-zone met…

We extend our previous work devoted to the computation of the next-to-next-to-leading order spin-orbit correction (corresponding to 3.5PN order) in t…

Post-starburst galaxies: more than just an interesting curiosity

From the VIMOS VLT DEEP Survey (VVDS) we select a sample of 16 galaxies with spectra which identify them as having recently undergone a strong starbu…

Accurate estimators of power spectra in N-body simulations

abridged] A method to rapidly estimate the Fourier power spectrum of a point distribution is presented. This method relies on a Taylor expansion of t…

Prompt high-energy emission from gamma-ray bursts in the internal sho…

The prompt GRB emission is thought to arise from electrons accelerated in internal shocks propagating within a highly relativistic outflow. The launc…

The retrograde orbit of the HAT-P-6b exoplanet

We observed with the SOPHIE spectrograph (OHP, France) the transit of the HAT-P-6b exoplanet across its host star. The resulting stellar radial veloc…
