Pulsars
  • Pulsars are fast spinning neutron stars
  • They are formed from large stars at the end of
    their lives in a super nova
  • They emit radio waves in beams from their poles

130 terabytes of data
  • Astronomers surveyed 30 of the sky
  • After 3 days at Green Bank, we started finding
    new pulsars
  • Our team was given 10 data sets, 30
    plots each
  • We started analyzing our data and

What we found
  • A lot of
  • RFI
  • And a bit more RFI
  • With
  • Some noise
  • And finally
  • Some interference

The Plots
  • Most of the plots looked like

RFI
RFI

  • After many, many plots
  • A few pulsars popped up
  • (We got excited...)

7
The Pulsars
  • In all, we found 6 pulsars
  • 3 of them were already in the ATNF database
  • The other 3 were unidentified pulsars

Conclusion
  • 94 of all the Pulsar data sheets were RFI and/or
    background noise. There were still a couple
    possible pulsars that we found.
  • Of the possible Candidate Pulsars, there were 3
    that were identified as already existing pulsars,
    while there were also 3 that were unidentified.
