Team Taylor: John, Lori, Casey, Tonia, Joey, Elizabeth, and Lazar Pulsar Search Collaboratory Project

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...)

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

KC's Unidentified Pulsar Broadband

Tonia's Space Noise Narrow Band

Liz's Pulsar

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.
