Is General Relativity a restricted theory?
Things should be made simple, but not simpler. What we want to show is that General Relativity, as it stands today, can be considered as a gravitational theory...

PublicationA pulse-timing model for pulsars in massive eclipsing binaries. Delays caused by high ratios between the pulsar period and orbital length.
We study the delay induced by gravitational light bending in the arrival times of signals emitted by an anisotropic source in rotation (pulsar). The shift of...

PublicationChallenging a Newtonian prediction through Gaia wide binaries
Under Newtonian dynamics, the relative motion of the components of a binary star should follow a Keplerian scaling with separation. Once orientation effects and...

TalkCosmology on small scales: the structure of (mostly) dark matter halos
The standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...
