... His adult life was devoted to the study of the discipline that he loved, astronomy, and to the promotion of the Observatory at Mount Stromlo, and of The Australian National University. ... He then won an ANU Scholarship to study at Stromlo, and embarked on his PhD there, in spite of the fact that the (then) Commonwealth Observatory's transfer to the ANU was still a few years off. ... Alex had a great love for Stromlo and the ANU. ...

... AstroAsciiData is a Python module to handle ASCII tables. ... The idea to develop this Python module emerged from the fact that ASCII tables continue to be one of the most popular and widely used data exchange formats in astronomy and probably science in general. ... To load this ASCII table, go into Python, load the AstroAsciiData module and read in the table with: . ... demo = asciidata.open('webexa.txt') . ... Users who only want to work with ASCII tables neeed no further python modules. ...

... Continous developing since 1978 · It can simulate many of this parameters and produce a spectra output · Much of the properties of the ionized gas (kinetic temperature, chemical state, level of ionization, and level populations...) are determined by microscopic processes, rather than a single temperature · We can run cloudy with different input datasets and compare the outputs with the real data Cloudy project web: www.nublado.org Why CLOUDY? ...

ALMA | ... Phase Correction Algorithms | ... On this page, we describe what the phase correction algorithms set out to do and the framework we have developed to optimally use all of the available information. ... We are developing a Bayesian framework to combine all the information we have about the current and future meterological conditions (which are naturally accommodated as priors in a Bayesian scheme) with detailed physical models of the atmosphere. ...

Physical parameters for subdwarf B stars with composite spectra R. Aznar Cuadrado, C.S. Jeffery, Armagh Observatory, College Hill, Armagh BT61 9DG New intermediate-resolution spectra have been obtained for a number of subdwarf B stars having both single and composite spectra. Physical parameters have been determined for the sdB stars and, in composite-spectrum systems, their cool companions. ... The surface gravity of the cool star is measured using the infrared calcium triplet. ...

SITE 2010 Comprehensive Characterization of Astronomical Sites Kislovodsk, Russia, 49 October 2010 Conference Summary Marc S. Sarazin*a a European Southern Observatory, Garching, Germany Abstract The main topics discussed during the Site 2010 conference are outlined and the outcome is described. Keywords: Astronomical Site testing, precipitable water vapor, atmospheric turbulence, cloudiness, seeing 1. ... Site surveys for National observatory projects in China, India, and Iran benefit from this. ...

... The first three detectors we built employed lenses and image intensifiers, newer detectors have direct fiberoptic coupling and no image intensification. ... This detector is now being used to perform additional tests of x-ray converters, fiberoptics and CCDs (Nagarkar et al., ... The construction and performance of directly-coupled fiberoptic/CCD detectors is critically dependant on two technologies; x-ray-to-light converters, and the efficient coupling of the CCD to the fiberoptic taper. ... Noise....

Next: The evolution equation Up: ``Ecology'' of Magnetic Rotators Previous: The Gravimagnetic Parameter . ... Such an approach to the evolution was developed in the 1970s by Schwartzman (1970a)[ 173 ], Bisnovatyi-Kogan and Komberg (1974, 1975)[ 15 , 16 ], Illarionov and Sunyaev (1975)[ 76 ], Shakura (1975)[ 178 ], Wickramasinghe and Whelan (1975)[ 212 ], Lipunov and Shakura (1976)[ 109 ], Savonije and van den Heuvel (1977)[ 171 ] and others. ...

pine is a mail program developed at the University of Washington. It has easy-to-remember single character commands and a menu interface which displays those available at each point. You might choose to use pine if you like learning new tools by exploration rather than reading a manual. The menu system is designed to handle mistakes by new users, and the on-line help system offers advice specific to whatever screen you are currently viewing. Start using pine with the command: pine . ...

These close-up images, taken by an electron microscope, reveal tiny one-cell organisms called halophiles and methanogens. In a two-year laboratory study, scientists subjected these organisms to increasingly lower temperatures to determine the coldest temperatures at which the microbes could survive and reproduce. The study shows the microbes could survive at below-freezing temperatures and are within the temperature range on present-day Mars. ... Maryland Astrobiology Consortium/NASA/STScI ...

... The following results were achieved in the course of S.P.Korolev RSC Energia's launch vehicle development efforts: . ... Two-stage intercontinental ballistic missiles R-7 and R-9, three-stage Vostok launch vehicle (consisting of R-7 and upper stage Block E as a third stage) for missions to the Moon, and four-stage Molniya launch vehicle for launching payloads to Venus and Mars (consisting of R-7 and upper stages Block I and Block L) were developed; . ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...
