We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. The best detectors for observing solar particles are therefore those sensitive to the lowest energies of the cosmic radiation. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

An astronomer by training, I currently work at the Australia Telescope National Facility , part of the CSIRO .

SAS home . ... List of SAS threads . OM data processing from A to Z is performed by two "chains": omichain and omfchain , for image and fast mode data respectively. ... Then a source detection algorithm is used to identify the sources present in the image. ... A final source list is obtained from all exposures and filters. ... If the user has PPS products from the processing of his/her observation, or from the XSA, then the first thing to do is to overlay the image source list onto the sky image. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE PROCESS OF SCIENCE: HOW DO WE KNOW? The nature of the universe, its age, its birth and life story, have been deduced through the process of science. ... In the case of astronomy, it usually starts with making careful observations and measurements -- something your students can begin to do through inspection of astronomical images, and observation of the real sky. ...

The VIRGO project is a physics experiment; its aim is the detection of gravitational waves. ... It has not yet been possible to detect directly the gravitational waves: it remains one of the major challenges of experimental physics. ... Interferometric antennas for gravitational waves Gravitational waves distort space-time: along two perpendicular directions, the distances between fixed points will increase (resp. decrease), at the arrival of a gravitational wave. ...

Microsymposium 34, MS047, 2001 SOME PROBLEMS OF THE EVOLUTION OF ASTEROIDS ­ RUBBLE PILE. ... Evidently, we can distinguish two processes: distant interactions, where there is no direct contact between separate fragments, and close contact interactions, where the fragments collide with one another. ... Such a rubble pile with a dust atmosphere differs from a cometary nucleus only in the absence of a volatile gas component, which is usually considered the cause of the appearance of cometary dust. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... The disc accretion process is an essential component of star and planet formation theories. ... Much of the detailed knowledge of the physical processes involved in disc accretion have been gained through observations of nearby ( Z ) of the local environment are thought to affect PMS disc accretion rates, and disc evolutionary timescales. ... I measure the accretion rates of these PMS stars using the intensities of the U /H band excess measured through either optical spectra or imaging. ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
