Einstein@Home starts processing Arecibo "Mock" data

Submitted on 21 Jul 2011 18:53:38 UTC

We have finished generating the last workunits for the Einstein@Home search of the Parkes Multi-Beam Pulsar Survey (PMPS) data set. This search should wind up in the coming weeks as these final workunits are processed by our volunteers. The Einstein@Home PMPS search has already found five new radio pulsars, and we hope that there are still a few more waiting to be found.

Today we launched the first "Binary Radio Pulsar" (BRP4) workunits, which are searching fresh radio data from the Arecibo Observatory. This data has been obtained at Arecibo using a new wideband back-end spectrometer, named after its creator Jeff Mock. The Arecibo data previously processed on Einstein@Home was acquired using the "WAPP" back-end, which has a 100 MHz bandwidth in 256 channels. The new Mock data which we are starting to process today has a 300 MHz bandwidth in 1024 channels. This will permit deeper and more sensitive Arecibo searches than ever before.

Thank you for contributing to Einstein@Home!

    Thanks for the update and congratulations on discovering five radio pulsars. Looking forward to the new work units.

      It is exciting to be able to crunch data from the newly upgraded equipment!

      Here is to many more new pulsars...

          Man, I remember making pulsar observations at Arecibo using an analog filter bank that had 32 250 kHz channels (you want narrower bandwidth per channel to find and accurately time those high DM millisecond pulsars). So, this new back end gives you 32 times the data (and sensitivity). I look forward to seeing more exciting results!

            I'm pleased that Bruce has explained the "Mock" bit, as I immediately thought it denoted some type of process validation test along the lines of the LIGO hardware/software injections. Then again, maybe there are pulsar signals that sound like they're laughing at you. But I'm sure Mr Mock has heard all variants of puns upon his name, so my apologies in advance .... :-)

            Cheers, Mike.
