Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design of a radio astronomy spectral line and pulsar observing system. This system will be part of the 20-m telescope at NRAO1 and will be used by the radio SkyNet project for radio astronomy outreach. Radio astronomical observations using this system are done in the X-Band (8-10 GHz). The system can be broadly divided into three units consisting of a super heterodyne receiver, a FPGA based digital spectrometer and a data acquisition unit. The super heterodyne receiver amplies, filters and down-converts the incoming radio sky frequency (RF) signal in the X-band to an intermediate frequency (IF) 500 MHz band signal, centered at 750 MHz. A tunable local oscillator selects the 500 MHz bandwidth in the band of sky frequencies. The IF signal is fed to the digital spectrometer. The high speed 8-bit analog to digital converter (ADC) in the spectrometer samples the IF signal at 1 Gs/s. The 8-bit ADC provides the high dynamic range required for the system. The digital outputs from the ADC are fed to the Xilinx Virtex V FPGA in ROACH2 board. A polyphase filter bank FFT spectrometer is implemented in the FPGA using CASPER3 technology. The spectra are accumulated for a specified integration time and dumped out into a host computer through a 10 Gigabit Ethernet (GbE) link. The characterization of the ADC and spectrometer are presented. The band pass stability of the spectrometer is measured to be 1000 s and hence any observations should measure a reference spectrum within this time. Since the front-end receiver was not available, the functionality of the spectrometer was tested using an L-Band (21cm) receiver system of the 43m radio telescope at NRAO. We have successfully detected HI emission from the Andromeda galaxy and signals from the Pulsar B0329+54.

Available in PDF, EPUB and Kindle. Book excerpt: Review of Volume 4:'The Handbook can be a good reference for a higher-degree science student approaching the subject or for an expert in a similar field in astronomical instrumentation. The reader requiring an in-depth presentation of a specific topic will be guided by the rich reference lists included at the end of each chapter.'The ObservatoryOur goal is to produce a comprehensive handbook of the current state of the art of astronomical instrumentation with a forward view encompassing the next decade. The target audience is graduate students with an interest in astronomical instrumentation, as well as practitioners interested in learning about the state of the art in another wavelength band or field closely related to the one in which they currently work. We assume a working knowledge of the fundamental theory: optics, semiconductor physics, etc. The purpose of this handbook is to bring together some of the leading experts in the world to discuss the frontier of astronomical instrumentation across the electromagnetic spectrum and extending into multimessenger astronomy.

Available in PDF, EPUB and Kindle. Book excerpt: This is quite simply the first volume of its kind dedicated to the area of high time resolution astrophysics. High time resolution astrophysics (HTRA) is an important new window on the universe and a vital tool in understanding a range of phenomena from diverse objects and radiative processes. Underlining this science foundation, technological developments in both instrumentation and detectors are described.

Available in PDF, EPUB and Kindle. Book excerpt: Enhanced sensitivity radio telescopes are producing dramatic results. An international conference was held in Jodrell Bank to take stock of these advances. This timely volume presents the review articles presented by a host of world experts who gathered at this meeting. We are shown how high sensitivity is advancing our understanding in radio spectral line analysis, radio continuum observations of galaxies, cosmology, pulsars, and radio emission from stars; what new and enhanced instruments are now available and those planned for the future. This volume provides graduate students and researchers with an up-to-date and wide-ranging review of the new and future research possible with high-sensitivity radio telescopes.

Available in PDF, EPUB and Kindle. Book excerpt: From the reviews: Astronomy and Astrophysics Abstracts has appeared in semi-annual volumes since 1969 and it has already become one of the fundamental publications in the fields of astronomy, astrophysics and neighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. ... The abstracts are classified under more than hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world." Space Science Reviews #1 "Dividing the whole field plus related subjects into 108 categories, each work is numbered and most are accompanied by brief abstracts. Fairly comprehensive cross-referencing links relevant papers to more than one category, and exhaustive author and subject indices are to be found at the back, making the catalogues easy to use. The series appears to be so complete in its coverage and always less than a year out of date that I shall certainly have to make a little more space on those shelves for future volumes." The Observatory Magazine #1
