Supernova Remnants with Fermi Large Area Telescope

EPJ Web of Conferences, 2017
The Large Area Telescope (LAT), on-board the Fermi satellite, proved to be, after 8 years of data taking, an excellent instrument to detect and observe Supernova Remnants (SNRs) in a range of energies running from few hundred MeV up to few hundred GeV ...

Modelling and design of a coupled system of multiple hydraulic systems and large structures

Nihon Kikai Gakkai ronbunshu
Control of large structures often involves the use of hydraulic equipment due to the large power requirements. In this study, a large telescope is taken as an example of a large structure.

Design and Preliminary Ground Experiment for Deployable Sunshade Structures of a Modular Space Telescope

Sensors
On-orbit assembling space telescope (OAST) is one of the most feasible methods to implement a large-scale space telescope. Unlike a monolithic space telescope (such as Hubble Space Telescope, HST) or a deployable space telescope (such as James Webb Space

Extremely Large Telescopes [PDF]

Proceedings of From Planets to Dark Energy: the Modern Radio Universe — PoS(MRU), 2008
Extremely large telescopes are being planned to address a number of the most profound questions in astronomy today. From the detection and study of extra-solar planets to the study of the first galaxies these optical and infrared telescopes are designed to provide powerful new probes in the field.

Active Surface Compensation for Large Radio Telescope Antennas

International Journal of Antennas and Propagation, 2018
With the development of radio telescope antennas with large apertures, high gain, and wide frequency bands, compensation methods, such as mechanical or electronic compensation, are obviously essential to ensure the electrical performance of antennas that

Interferometry with Large Telescopes [PDF]

International Astronomical Union Colloquium, 1984
1. Introduction. A popular - often textbook supported- view is that the diffraction limit of large telescopes is out of reach from ground-based observatories.We summarize on Fig.1 the scope of angular resolving power, in the range lOOnm to 10. nm, as it appears today.A quick look reveals, expressed in absolute angular terms, a number of stimulating ...
