Time Calibration of the ANTARES Neutrino Telescope

The ANTARES deep-sea neutrino telescope comprises a three-dimensional array of photomultipliers to detect the Cherenkov light induced by upgoing relativistic charged particles originating from neutrino interactions in the vicinity of the detector. The large scattering length of light in the deep sea facilitates an angular resolution of a few tenths of a degree for neutrino energies exceeding 10...

Cost-Sensitive Batch Mode Active Learning: Designing Astronomical Observation by Optimizing Telescope Time and Telescope Choice

Astronomers and telescope operators must make decisions about what to observe given limited telescope time. To optimize this decision-making process, we present a batch, cost-sensitive, active learning approach that exploits structure in the unlabeled dataset, accounts for label uncertainty, and minimizes annotation costs. We first cluster the unlabeled instances in feature space. We next intro...

Time calibration system for the KM3NeT deep sea neutrino telescope

In this contribution we review the time calibration system proposed for the future underwater KM3NeT neutrino telescope. Building on the experience gained with the pilot projects, ANTARES, NEMO and NESTOR, and the results in-situ from the ANTARES Optical Beacons, we propose a decoupled optical system, based on LEDs and lasers, to perform an intra-line and inter-line relative time calibration. T...

The Liverpool Telescope Automatic Pipeline for Real - time GRB

— The 2-m robotic Liverpool Telescope (LT) is ideally suited to the rapid follow-up of unpredictable and transient events such as GRBs. Our GRB follow-up strategy is designed to identify optical/IR counterparts in real time; it involves the automatic triggering of initial observations, on receipt of an alert from Gamma Ray Observatories HETE-2, INTEGRAL and Swift, followed by automated data red...
