Scalable splitting algorithms for big-data interferometric imaging in the SKA era

Jean-Philippe Thiran, Yves Wiaux, Rafael Eduardo Carrillo Rangel, Jason Douglas McEwen

In the context of next generation radio telescopes, like the Square Kilometre Array, the efficient processing of large-scale datasets is extremely important. Convex optimisation tasks under the compressive sensing framework have recently emerged and provid ...

Evaluating the effect of stellar multiplicity on the point spread function of space-based weak lensing surveys

Frédéric Courbin, Georges Meylan, Thibault Adrien Kuntzer

The next generation of space-based telescopes used for weak lensing surveys will require exquisite point spread function (PSF) determination. Previously negligible effects may become important in the reconstruction of the PSF, in part because of the improv ...

Infrared Vibrational Molecular Hybridization with a Single Optical Antenna

Hatice Altug

We observe impedance matched coupling between molecular vibrations and infrared optical antennas. Broadband synchrotron near-field spectroscopy reveals antenna-vibration hybridization, mode splitting, and tip excitation of coupled dark plasmon modes. ...

Potential of the Large Observatory for X-ray Timing telescope for the search for dark matter

Alexey Boyarsky, Oleg Ruchayskiy

Large observatory for x-ray timing (LOFT) is a concept of a next-generation x-ray telescope considered in the context of the "Cosmic Vision" program of the European Space Agency. The Large Area Detector on board of LOFT will be a collimator-type telescope ...

Design and operation of FACT - the first G-APD Cherenkov telescope

Mathieu Ribordy, Werner Lustermann, Thomas Günther Bretz, Camille Haller

The First G-APD Cherenkov Telescope (FACT) is designed to detect cosmic gamma-rays with energies from several hundred GeV up to about 10 TeV using the Imaging Atmospheric Cherenkov Technique. In contrast to former or existing telescopes, the camera of the ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIV. Time delay of the doubly lensed quasar SDSS J1001+5027

Frédéric Courbin, Georges Meylan, Malte Tewes

This paper presents optical R-band light curves and the time delay of the doubly imaged gravitationally lensed quasar SDSS J1001+5027 at a redshift of 1.838. We have observed this target for more than six years, between March 2005 and July 2011, using the ...

Switchable telescopic contact lens

We present design and first demonstration of optics for a telescopic contact lens with independent optical paths for switching between normal and magnified vision. The magnified optical path incorporates a telescopic arrangement of positive and negative an ...

A Raman lidar to measure water vapor in the atmospheric boundary layer

Hubert van den Bergh, Valentin Simeonov, Marc Parlange, Chad Higgins, Martin Froidevaux, Eric Richard Pardyjak, Pablo Roberto Ristori, Ilya Serikov

A new multi-telescope scanning Raman lidar designed to measure the water vapor mixing ratio in the atmospheric boundary layer for a complete diurnal cycle with high resolution spatial (1.25 m) and temporal (1 s) resolutions is presented. The high resolutio ...

Introducing the CTA concept

Mathieu Ribordy, Steve Couturier, Thomas Günther Bretz, Werner Lustermann, Christophe Bauer, Francisco Sanchez, Xiaoqing Zhou, Reto Frei, Etienne Antoine Julien Moulin, Michael Werner, Bruno Garcia, Munehito Kagaya

The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span abou ...

Design constraints on Cherenkov telescopes with Davies-Cotton reflectors

Mathieu Ribordy, Thomas Günther Bretz

This paper discusses the construction of high-performance ground-based gamma-ray Cherenkov telescopes with a Davies-Cotton reflector. For the design of such telescopes, usually physics constrains the field-of-view, while the photo-sensor size is defined by ...
