Meteor detection in wide-field survey telescopes [PDF]
, 2014 Meteor observing requires a huge field of view (FoV) as its appearance in the sky cannot be foreseen. In the new era of the time-domain astronomy many telescopes will cover the whole sky with a cadence of a few days. These requirements lead to fast large telescopes with wide FoVs, like the Schmidt cameras that were widely used for meteor observing in ...

A double‐crystal bent Laue parallel‐beam compressor
Journal of Synchrotron Radiation, EarlyView.An application of bent Laue crystals as X‐ray optics to increase beam intensity in bending‐magnet beamlines at synchrotron facilities is presented.We demonstrate the ability to manipulate a synchrotron X‐ray beam's size, maintaining a nearly parallel beam, by `compressing' it horizontally using a pair of cylindrically bent Laue crystals.

Study of Double-mode RR Lyrae Stars in the Stripe 82 Region Using SDSS and ZTF
The Astronomical JournalRRd stars are a subclass of RR Lyrae stars that pulsate simultaneously in the fundamental and the first-overtone radial modes. We report the analysis of 10 RRd stars discovered in the Sloan Digital Sky Survey (SDSS) Stripe 82 region of the Galactic halo ...

Global Policy, EarlyView.ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Astrometry with the Wide-Field InfraRed Space Telescope
, 2017 The Wide-Field InfraRed Space Telescope (WFIRST) will be capable of delivering precise astrometry for faint sources over the enormous field of view of its main camera, the Wide-Field Imager (WFI). This unprecedented combination will be transformative for the many scientific questions that require precise positions, distances, and velocities of stars ...

Annals of Applied Biology, EarlyView.We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...
