Appetite comes with eating: EXTraS PASTA & SOPA @ OAR
settembre 26 @ 11:45 - 12:45
Data mining of public archives is a powerful tool in modern astronomy and it is expected to be more and more important in the near future since the size and number of experiments is rapidly increasing . Focus is put on the millions of objects falling by chance in the field of view of astronomical observations and left mostly ignored. In the EXTraS project we tapped into the poorly studied sources included in the 3XMM catalog, characterizing their variability with unprecedented detail. The products of the EXTraS project has been published in on-line catalogues open to the whole scientific community. At OAR, in particular, we searched for periodic variability of near 1.5 M timeseries. The main results of my work will be briefly shown.
Additionally, with the newly developed pipelines PASTA (Pulsation Accelerated Search for Timing Analysis) and SOPA (Searchfor Orbital Periods with Acceleration) we aim to dig even deeper into this huge amount of data by means of CINECA supercomputer facilities. I will tell you about these projects, some of their results and the prospectives of Data Mining and Big Data automatic analysis at the OAR.
