DanceCam: atmospheric turbulence mitigation in wide-field astronomical images with short-exposure video streams
Spencer Bialek, Emmanuel Bertin, Sébastien Fabbro +4
We introduce a novel technique to mitigate the adverse effects of atmospheric turbulence on astronomical imaging. Utilizing a video-to-image neural network trained on simulated dat…
SPHERE RefPlanets: Search for epsilon Eridani b and warm dust
C. Tschudi, H. M. Schmid, M. Nowak +35
We carried out very deep VLT/SPHERE imaging polarimetry of the nearby system Eps Eri based on 38.5 hours of integration time with a 600 - 900 nm broadband filter to search for pola…
A multi-scale multi-lane model for traffic regulation via autonomous vehicles
Paola Goatin, Benedetto Piccoli
We propose a new model for multi-lane traffic with moving bottlenecks, e.g., autonomous vehicles (AV). It consists of a system of balance laws for traffic in each lane, coupled in…
Projectivity criteria for Kähler morphisms
Benoît Claudon, Andreas Höring
In this short note we prove two projectivity criteria for fibrations between mildly singular compact Kähler spaces. They are the relative versions of the celebrated criteria of Kod…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Reduction of dust radial drift by turbulence in protoplanetary disks
Fabiola Antonietta Gerosa, Jérémie Bec, Héloïse Méheut +1
Dust particles in protoplanetary disks, lacking support from pressure, rotate at velocities exceeding those of the surrounding gas. Consequently, they experience a head-wind from t…
