Data Handling and Products . ... ESO Data . ... Studies of the Planck data set with optical and sub-mm follow-up observations give new insights about the early assembly of the first clusters, and the later evolution of their gas content as well as of their population of star-forming galaxies. ...

Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...

Next: Radiopulsars as Sources of Up: Cosmic Rays and Evolution Previous: Cosmic Rays and Evolution . Presently, there is little doubt that galactic CR can be generated at rapidly expanding shock fronts produced by supernova explosions. ... Statistical properties of radiopulsars in our Galaxy indicate a formation rate of NS of about 1 per 10-20 years in the present cosmological epoch, while direct astronomical observations have so far not detected supernova explosions at this high rate. ...

... The main field of our team interests is the researching of galaxy clusters as well as single nearby galaxies. The galaxies and galaxy clusters, being gravitationaly bound and reliably distinguishable systems, allow us to determine their global physical characteristics. At the same time they are integrated as elements into higher level spatial structures or systems. ... Вack to main homepage . ...

Multifrequency Observations of S­Z Effect toward clusters of galaxies M. De Petris et al. ... We describe a dedicated instrument (MITO) consisting of a 2.6­m telescope operating at 3500 m a.s.l. in the 2.1, 1.4, 1.1 and 0.8 mm channels with ё 10% bandwidths. Forthcoming results to­ ward A1656 cluster are reported and discussed in terms of thermal and non­thermal components. ...

Some astronomers ignore low-mass stars because they aren t very bright. However, stars with initial masses between about 0.8 Msun and 8 Msun (AGB stars) play an important role as the main site of the slow neutron capture (s-)process, which produces roughly half of the elements heavier than iron. ... From this work, we will see have a better understanding of AGB nucleosynthesis, the chemical evolution of globular clusters, and the properties of helium-rich stars. ...
