Cagliari Astronomical Observatory ( International Latitude Station )

The Cagliari Astronomical Observatory was established as International Latitude Astronomical Station of Carloforte in 1899, a small town of the sardinian island of S. Pietro. It has been, for about 80 years, one of the five international stations devoted to study the Earth rotation and polar motion. Observations with the zenital telescope were carried out, except in the period of the second world's war. Starting from 1978, the headquarters were moved to Punta Sa Menta, a site 15 km far from Cagliari which has the same latitude of the Carloforte station.

Cosmological Constant Conference

International Conference on "The Cosmological Constant and the Evolution of the Universe", The University of Tokyo (Tokyo, Japan), November 7 - 10, 1995
Observational data, such as the Hubble constant measurements and estimates of the age of globular clusters, have strongly suggested the existence of nonvanishing cosmological constant. It is, however, quite difficult to explain the observationally suggested value on purely theoretical grounds. The purpose of the Conference was to bring together the observational data and theoretical ideas concerning the cosmological constant.

Cosmological Parameters Poll

The purpose of this opinion poll is to survey current believes, held by professionals and the informed public, on what should be the correct values of the Hubble constant, the cosmic density parameter, Omega, and the cosmological constant, Lambda, and to monitor changes as new observational and theoretical results become available.

Cosmology - Explore the largest mystery

Cracow - Solar radio emission in dm wavelength

Continuous observations of solar radio emission in decimeter wavelength have been maintained in Cracow since 1957. Beginning from January 1995 we provide the reduced data on-line. The new instrument for solar radio observations is under construction. It is to start its operation in May, 1995.

Cracow Observatory

The Astronomical Observatory is an institute in Faculty of Mathematics and Physics at the Jagiellonian University in Cracow, Poland. Nowadays the scientific staff of 36 people works on: physics of comets, photometry of variable stars, solar radio emission observations, investigation of extragalactic radio sources, active galactic nuclei, interstellar and intergalactic matter, physics of galaxies, large scale structure of the Universe and theoretical cosmology.

Crawford Astronomy Collection ( ROE )

The Royal Observatory, Edinburgh, possesses one of the most comprehensive collections of astronomical literature in existence. The library system, which serves the professional community, comprises the Crawford Library, Main Library and Archives. The Main Library holds twentieth century material covering all fields of astronomy. Supporting subjects are represented by a select stock of works on physics, electronics and computing. All post-1973 publications are available through the Library's on line catalogue. The Observatory Archives comprise the notebooks, correspondence and other papers of the former Astronomical Institution of Edinburgh, Astronomers Royal for Scotland, and the 26th Earl of Crawford. The collection which includes early instruments, equipment and photographic material, has been sorted and indexed. The Crawford Library contains some 15,000 books, pamphlets and manuscripts dating from the thirteenth century to the end of the nineteenth century. The collection was brought together by the 26th Earl of Crawford from his family library, the library of Charles Babbage and purchases of rare books from booksales throughout Europe. The Library contains first editions of all major works in the history of astronomy and related fields. It is recognised as a rich resource for scholars, historians of science and bibliographers and is visited by researchers from all over the world.

Create your own Stellar Population ( Dial-a-model )

This form allows users to cook up arbitrary combinations of single-burst stellar population ages and metallicities. A grid of models is automatically consulted and properties of the requested population (integrated colors, M/L ratios, SBF magnitudes, and line strengths) are immediately returned. Optionally, the entire SED (spectral energy distribution) is sent to the user in a file.

Curtis Schmidt Telescope

The Curtis Schmidt telescope is a 0.61/.91 meter diameter Schmidt telescope located at the Cerro Tololo InterAmerican Observatory, about 500 km north of Santiago, Chile. This telescope was originally installed at the University of Michigan's Portage Lake Observatory in 1950, and moved to the much clearer skies of north central Chile in 1966. Two thirds of the time on this telescope is available to US and Chilean astronomers, with the remaining one third reserved for astronomers from the Dept. of Astronomy at the University of Michigan.
