Yuki Searches for Millisecond* Pulsars!

* Isn't it amazing that some star rotated many 1000s of times while you read this sentence?

My paper: A Search for New Millisecond and Submillisecond Pulsars

If you look closely, the search headers for the data are pretty informative...

When you look up at the sky (1st plot), or when you look at the Milky Way (2nd plot), I'm taking care of pulsars in this area: (My data covers 1300 deg², or 3% of the whole sky:)

(3rd plot): I could find pulsars with periods and dispersion measures above this blue curve ^

My data has 21 already-known pulsars.

Pulses of an already discovered (not by me:) pulsar:

and millisecond pulsars:

Since Spring 1999, Adam Chandler (and Bryan Jacoby and Walid Majid) has taken over the search.

In August 2000, Adam (and Rick) went to Arecibo for 18 days, and ...

2000/8/24: Adam found the 1st new pulsar from our data!!
