... Up: Science Data Pipelines . ... The Chandra Automatic Data Processing System (AP) requires quick access to previously generated data. ... This archive interface layer includes an archive request queue, a data archiving server (darch), and an archive ``cache''. ... In our implementation, the cache is actually a directory where the data files reside, as shown in Figure 1 . ... If the data products are not in the cache, then the pipeline retrieves the files from the archive database. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...
