  1. Disney Reaches for the Stars Erin W Gunner H Anna D Shane C Carly L Shane S. Mentor: Sean

  2. Introduction • Project: to analyze data collected by the Green Bank telescope and search for pulsars • Goals: • Identify known pulsars, RFI, and new pulsars • Investigate variations in periods • Sort noise from significant data

  3. Harmonics in Motion Known Pulsar Info: Dec: -13:54 RA: 09:44 DM: 12.5 Period: 0.57026

  4. Radio Frequency Interference (R.F.I) Documented in Rogue Gallery as a power line Period ~ 1198 ms

  5. Known Pulsar • J1610-1322 • Comparisons: • RA and Dec changed slightly from known pulsar in catalogue • ~ no change in DM

  6. GBT Candidates • Not in ATNF • New pulsar, named J2013-06 in new drift scan data • Never before seen at 800 MHz. • Strong pulse profile against noise.

  7. 2013-0650 Comparison • Much clearer lines. • In 2007 it was observed at a frequency of 350 MHz and now it was observed at a frequency of 800 MHz. • Little period change

  8. GBT Candidates • Strong vertical lines in the Sub-band Plot. • Low probability of noise. • Definitely not a known pulsar.

  9. GBT Comparison • Investigation looks more like RFI than 2007 data • We were very disappointed. • No period change

  10. Conclusions • Uncertainties/Questions • Could harmonics be different pulsars? • Why is there a difference when the pulsar was observed at 350 MHz and 800 MHz? What can we learn about the pulsar? • Certainties • About 30 plots with extremely close DM values • RFI is present in almost half of the plots examined (47%) • Saw 3 known pulsars
