— We present the first optical observations of a Gamma Ray Burst (GRB) afterglow using the 2-m robotic Liverpool Telescope (LT), which is owned and operated by Liverpool John Moores University and situated on La Palma. We briefly discuss the capabilities of LT and its suitability for rapid follow-up observations of early optical and infrared GRB light curves. In particular, the combination of a...

Speckle interferometric technique is used to record a series of short exposure images of several close binary stars with sub-arcsecond separation through a narrow band filter centred at Hα at the Cassegrain focus of the 2.34 meter (m) Vainu Bappu telescope (VBT), situated at Vainu Bappu Observatory (VBO), Kavalur. The auto-correlation method is developed under Image Reduction Analysis Facility ...

OBJECTIVE To describe the surgical procedure for placement of an implantable telescope prosthesis for end-stage age-related macular degeneration. METHODS As part of a phase 2/3 clinical trial for patients with bilateral, irreversible age-related macular degeneration, the optimal procedure for monocular placement of the telescope prosthesis was determined. RESULTS Because of the unique confi...

Data-driven understanding of cybersecurity posture is an important problem that has not been adequately explored. In this paper, we analyze some real data collected by CAIDA’s network telescope during the month of March 2013. We propose to formalize the concept of cybersecurity posture from the perspectives of three kinds of time series: the number of victims (i.e., telescope IP addresses that ...

With an effective telescope area of order 10 m for TeV neutrinos, a threshold near ∼50 GeV and a pointing accuracy of 2.5 degrees per muon track, the AMANDA detector represents the first of a new generation of high energy neutrino telescopes, reaching a scale envisaged over 25 years ago. We describe early results on the calibration of natural deep ice as a particle detector as well as on AMANDA...

Construction of IceCube at the Amundsen-Scott South Pole Station was completed at the end of 2010 after eight construction seasons. The detector consists of 5,160 digital optical modules on 86 cables with 60 modules each, viewing in total a cubic kilometer of ice between 1,450 and 2,450 meters below the surface. IceCube includes a sub-array called DeepCore consisting of 8 special cables, and pr...

A project to construct a 17m ø imaging air Čerenkov telescope, dubbed MAGIC Telescope (Major Atmospheric Gamma Imaging Cerenkov Telescope), for the observation of high energy cosmic gamma rays is described. The main aim is to explore gamma-ray sources in the up to now unexplored energy range between 20-200 GeV. The telescope will incorporate several novel features such as a high quantum efficie...
