Scientific Results Obtained Using Grid Technology

Oral

Several techniques have been proposed to detect the SZ clusters. Most of them are based on linear filters that try to take into account the frequency dependance of the SZ effect to combine information from different channels to produce a single map where the clusters can be detected with a higher SNR than in the individual frecuency maps (Planck will image the microwave sky in nine...

Existing or Prospective Grid Services

Oral

Astrophysical applications handle simulated, theoretical and observed data and the amount of data requested by a single application is not negligible. Astronomical data are usually kept in databases most of them are now federated in the VObs. Users accessing these data usually expect some key capabilities like: a) find data by specifying their characteristics; b) retrieve them whatever is...

Scientific Results Obtained Using Grid Technology

Oral

Evidence for the accelerated expansion of the Universe has been observed in the last decade with the many cosmological observations. The origin of accelerated expansion remains one of the most challenging research activities today. Progress in this field requires both theoretical innovations and many accurate observational probes with controlled systematic error estimates. The difficulty in...
