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
RFI (Radio Frequency Interference)
Documented in Rogue Gallery as a power line
Period ~ 1198 ms
Harmonics
Same known pulsar appears in about 30 different periods
Known Pulsar Info:
Dec: -13:54
RA: 09:44
DM: 12.5
Period:
GBT Comparisons
2007
2011
Known Pulsar J
Comparisons:
RA and Dec both increased.
~ no change in DM
Conclusions
Certainties
About 30 plots with extremely close DM values
RFI is present almost half of the plots examined (47%)
Saw 3 known pulsars
Uncertainties/Questions
Identifying fuzzy vertical patterns → use GBT to investigate further
Could harmonics be different pulsars?
