Resolving the vicinity of supermassive black holes with gravitational microlensing
Upcoming wide-field surveys will discover thousands of new strongly lensed quasars which will be monitored with unprecedented cadence by the Legacy Survey of Space and Time (LSST). Many of these quasars will undergo caustic-crossing events over the 10-yr L ...
Oxford Univ Press2024Imitation Learning in Discounted Linear MDPs without exploration assumptions
Volkan Cevher, Efstratios Panteleimon Skoulakis, Luca Viano
We present a new algorithm for imitation learning in infinite horizon linear MDPs dubbed ILARL which greatly improves the bound on the number of trajectories that the learner needs to sample from the environment. In particular, we re- move exploration assu ...
2024The completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: N-body mock challenge for the quasar sample
The growth rate and expansion history of the Universe can be measured from large galaxy redshift surveys using the Alcock-Paczynski effect. We validate the Redshift Space Distortion models used in the final analysis of the Sloan Digital Sky Survey (SDSS) e ...
OXFORD UNIV PRESS2020Gyrokinetic analysis of radial dependence and global effects on the zero particle flux condition in a TCV plasma
Olivier Sauter, Stephan Brunner, Gabriele Merlo, Alberto Mariani
In small-sized tokamaks, finite Larmor radius effects could lead to a significant discrepancy between gyrokinetic local flux-tube results and global ones. This has been highlighted by previous turbulent transport studies as in McMillan et al (2010 Phys. Re ...
IOP2019Time-projection control to recover inter-sample disturbances, application to bipedal walking control
Auke Ijspeert, Philippe Müllhaupt, Salman Faraji
We present a new walking controller based on 3LP, a 3D model of bipedal walking that is composed of three pendulums to simulate falling, swing and torso dynamics. Taking advantage of linear equations and closed-form solutions of 3LP, the proposed controlle ...
2018Toward an Internally Consistent Astronomical Distance Scale
Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to determine accurate distances, using a wide range of methods, tracers, and t ...
