    RF Interference Monitoring for the Onsala Space Observatory Master of Science Thesis (Communication Engineering) SYED AMEER AHMED GILLANI Department of Earth and Space Sciences, Onsala Space Observatory, CHALMERS UNIVERSITY OF TECHNOLOGY, Göteborg, Sweden, 2010. RF INTERFERENCE MONITORING FOR ONSALA SPACE OBSERVATORY SYED AMEER AHMED GILLANI Department of Earth and Space Sciences, Onsala Space Observatory CHALMERS UNIVERSITY OF TECHNOLOGY Göteborg, Sweden 2010 ii ABSTRACT With the continuous and rapid developments in wireless services and allocation of radio frequency spectrum to these services, huge interferences have been observed in the field of radio astronomy. According to the international regulations, parts of the spectra are reserved for radio-astronomical observations. Man-made signals entering the receiver chain of a radio telescope have much higher power compared to natural or passive signals received at the radio telescopes. Passive signals received at radio telescopes are normally 60 dB below the receiver noise level. Active signals generated by man-made wireless services pollute the natural emissions by completely masking them due to high signal strength. The cosmic radiation is determined by the fundamental laws of physics, thus the frequencies are fixed and cannot be changed. So interferences created by active services lead to wrong interpretations of the astronomical data. The present thesis deals with RF interference monitoring system for the Onsala Space Observatory. As part of the thesis, a software application has been developed, which communicates with different type of digital receivers (spectrum analyzers) attached with antenna controlling hardware to control omnidirectional and steerable antennas. A steerable antenna is used to find the direction of interference source by moving the antenna in azimuth and elevation direction.

  • Cutting-Edge Engineering for the World's Largest Radio Telescope
    SKAO Cutting-edge engineering for the world’s largest radio telescope Cutting-edge engineering for the world’s largest radio telescope Approaching a technological challenge on the scale of the SKA is formidable... while building on 60 years of radio- astronomy developments, the huge increase in scale from existing facilities demands a revolutionary break from traditional radio telescope design and radical developments in processing, computer speeds and the supporting technological infrastructure. To answer this challenge the SKA has been broken down into various elements that will form the final SKA telescope. Each element is managed by an international consortium comprising world leading experts in their fields. The SKA Office, staffed with engineering domain experts, systems engineers, scientists and managers, centralises the project management and system design. SKAO The design work was awarded through the SKA Office to these Consortia, made up of over 100 of some of the world’s top research institutions and companies, drawn primarily from the SKA Member countries but also beyond. Following the delivery of a detailed design package in 2016, in 2018 nine consortia are having their Critical Design Reviews (CDR) to deliver the final design documentation to prepare a construction proposal for government approval. The other three consortia are part of the SKA’s Advanced Instrumentation Programme, which develops future instrumention for the SKA. The 2018 SKA CalenDaR aims to recognise the immense work conducted by these hundreds of dedicated engineers and project managers from around the world over the past five years. Without their crucial work, the SKA’s ambitious science programme would not be possible.

  • All the Things That Back to the Future Got Right (And Wrong)
    All the things that Back to the Future got right (and wrong) Posted 7 days ago by i100 staff in ents Upvote Wednesday 21st October 2015 marks the date that Marty McFly and Doc Brown flew through time to visit in the 1989 classic Back to the Future II. While the film, directed by Robert Zemeckis and starring Michael J Fox and Christopher Lloyd, made many fanciful predictions which we're still waiting for, it was surprisingly correct in some aspects. Here's what it got right and what it got wrong about the world we live in, in 2015: Right Fingerprint scanners Fingerprint recognition, like that used to pay for a taxi in the film, can be found on the latest iPhones and at US passport control. Fuelling cars on rubbish While you can't exactly scavenge through a wheelie-bin and force feed it through your car's petrol cap (as Doc does to the DeLorean), using waste as a fuel - in the form of biogas, is something we use in 2015. There's even a bus in Bristol that runs entirely on human and food waste. Hoverboard transportation The kind with wheels may be banned on British streets, but inventors in the US have managed to create a real hoverboard using powerful electromagnets and a metal course. The Hendo II, fronted by renowned skateboarder Tony Hawk will be launched on Wednesday. Hands-free games A young Elijah Wood and his pal denounce Marty for using a video game that needs a handset in the film, suggesting that by 2015 hands-free computer games would be mainstream.

Supplementing them with the WENSS, NVSS and GB6 survey data we constructed the spectra of the studied galaxy components. We computed the spectral indices in the studied frequency range and demonstrate the need for a detailed account of the integral contribution of such objects into the background radiation.

  • Essential Radio Astronomy
    February 2, 2016 Time: 09:25am chapter1.tex © Copyright, Princeton University Press. No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. 1 Introduction 1.1 AN INTRODUCTION TO RADIO ASTRONOMY 1.1.1 What Is Radio Astronomy? Radio astronomy is the study of natural radio emission from celestial sources. The range of radio frequencies or wavelengths is loosely defined by atmospheric opacity and by quantum noise in coherent amplifiers. Together they place the boundary be- tween radio and far-infrared astronomy at frequency ν ∼ 1 THz (1 THz ≡ 1012 Hz) or wavelength λ = c/ν ∼ 0.3 mm, where c ≈ 3 × 1010 cm s−1 is the vacuum speed of light. The Earth’s ionosphere sets a low-frequency limit to ground-based radio astronomy by reflecting extraterrestrial radio waves with frequencies below ν ∼ 10 MHz (λ ∼ 30 m), and the ionized interstellar medium of our own Galaxy absorbs extragalactic radio signals below ν ∼ 2 MHz. The radio band is very broad logarithmically: it spans the five decades between 10 MHz and 1 THz at the low-frequency end of the electromagnetic spectrum. Nearly everything emits radio waves at some level, via a wide variety of emission mechanisms. Few astronomical radio sources are obscured because radio waves can penetrate interstellar dust clouds and Compton-thick layers of neutral gas. Because only optical and radio observations can be made from the ground, pioneering radio astronomers had the first opportunity to explore a “parallel universe” containing unexpected new objects such as radio galaxies, quasars, and pulsars, plus very cold sources such as interstellar molecular clouds and the cosmic microwave background radiation from the big bang itself.

This might be used to search for evidence of ionized halos around galaxies, using polarized radio sources as a probe. In this thesis I analyze the polarization properties of background radio sources from the Taylor et al. (2009) catalog based on observations with the Very Large Array, and correlate these to the angular separation between the radio sources and foreground galaxies. I find a decrease in the amount of polarized radio sources near the galaxies, interpreting this as radio sources being depolarized by galaxy halos.
