Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment

Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over the time coverage planned for the Gaia DR4, w ...

Space Oddity? A Statistical Formulation of Conjunction Assessment

Anthony Christopher Davison, Soumaya Elkantassi

Satellite conjunctions involving "near misses" of space objects are becoming increasingly likely. One approach to risk analysis for them involves the computation of the collision probability, but this has been regarded as having some counterintuitive prope ...

High-redshift supernova rates measured with the gravitational telescope A 1689

Jean-Paul Richard Kneib, Johan Richard

Aims. We present a ground-based, near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z = 0.18, which is one of the most powerful gravitational telescopes that nature provides. Methods. Our survey was based on multi-epoch J-b ...

Evaluation of Probabilistic Occupancy Map People Detection for Surveillance Systems

Pascal Fua, François Fleuret, Jérôme Berclaz, Seyed Ali Shahrokni

In this paper, we evaluate the Probabilistic Occupancy Map (POM) pedestrian detection algorithm on the PETS 2009 benchmark dataset. POM is a multi-camera generative detection method, which estimates ground plane occupancy from multiple background subtracti ...

Living specimen tomography by digital holographic microscopy: morphometry of testate amoeba

Christian Depeursinge, Tristan Colomb, Nicolas Pavillon, Benjamin Rappaz, Pierre Marquet, Edward Mitchell, Florian Charrière, Thierry Jean Heger

This paper presents an optical diffraction tomography technique based on digital holographic microscopy. Quantitative 2-dimensional phase images are acquired for regularly-spaced angular positions of the specimen covering a total angle of π, allowing to bu ...
