Galactic Cepheid Database ( DDO )

The Galactic Cepheid Database is a project of J. Donald Fernie that lists all known Population I cepheids. It consists of four tables listing data on 505 cepheids in the Galaxy. Information includes positional data, color excess determinations, periods, amplitudes and means of V, B and B-V derived by Fourier fits to magnitude and intensity light curves, radial velocities, distances, Z values, etc. Simple string searches of the database are possible using WWW client software such as NCSA Mosaic. The tables can be viewed in PostScript format or retrieved in either ascii or dBase IV versions.

Galaxies, Quasars & Cosmology ( PH308 )

This course is a third year undergraduate option taught by the Astronomy Group at Southampton University. The course is intended to provide a broad introduction to extragalactic astronomy: it is divided into three main sections, which cover the properties of normal galaxies, the nature of active galaxies, and our current understanding of cosmology.
The purpose of these WorldWide Web site is to provide direct access to some of my notes, to a number of the on-line resources used in preparing the lectures, and to further material. They are not a substitute for the lectures (at least, not yet)!

Galileo Project

A web resource on the life and works of Galileo Galilei (1564-1642).


The GALLEX experiment was performed by an international collaboration headed by MPIK Heidelberg. GALLEX measured the solar neutrino flux produced inside the Sun by proton-proton fusion. As target for neutrino capture, a large amount (30 tons) of the rare element Gallium in form of an aqueous solution of Galliumtrichloride was used. To protect the detector from the interfering cosmic radiation one must go deep underground. Hence the experiment was carried out under the shielding of Italy's highest mountain outside the Alps, the Gran Sasso d'Italia in the Abruzzo region.

Global Change Data and Information System ( GCDIS )

The Committee on Earth and Environmental Sciences (CEES), as prescribed by the Global Change Research Act of 1990, established a program whereby the United States Global Research Program (USGCRP) members committed to work together with each other, academia, and the international community to make it as easy as possible for researchers and others to access and use global change data and information. Toward this end, agencies participating in the USGCRP organized the Global Change Data and Information System (GCDIS) to take full advantage of the mission resources and responsibilities of each agency and to link the services of these data and information resources to each other.

Gravity Probe B Relativity Mission ( Stanford )

Gravity Probe B is the relativity gyroscope experiment being developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity. The experiment will check, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth satellite orbiting at 400-mile altitude directly over the poles. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are warped by the presence of the Earth, and, more profoundly, how the Earth's rotation drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe.

GRB Coordinates Network ( GCN )

The GRB Coordinates Network (used to be called BACODINE) system (1) calculates RA,Dec coordinate positions of Gamma Ray Bursts (GRB) detected with BATSE and distributes those positions around the world in real time -- a few seconds! -- so that other instruments can make follow-up observations in other wavebands while the burst is still bursting! (2) distributes locations of GRBs detected by other spacecraft. (3) distributes reports follow-up observations made by ground-based optical and radio observers.
These three functions provide a one-stop shopping network for follow-up sites and GRB researchers.

Green Flashes ( An Introduction )

Green flashes are real (not illusory) phenomena seen at sunrise and sunset, when some part of the Sun suddenly changes color (at sunset, from red or orange to green or blue). The word ``flash'' refers to the sudden appearance and brief duration of this green color, which usually lasts only a second or two at moderate latitudes.
