[75.06] Caltech-Arecibo Pulsar Drift Survey and Globular Cluster Searches

A. M. Chandler, S. B. Anderson, S. R. Kulkarni, T. A. Prince (California Institute of Technology)

We present recent results from two pulsar searches currently in progress.

We are searching 960 square degrees of drift survey data taken during the upgrade period. The data were taken in an 8 MHz bandwidth about a central frequency of 430 MHz using the 128 channel Penn State Pulsar Machine. This survey has ~ mJy sensitivity to sub-millisecond pulsars. We have detected 19 previously known pulsars, and as of the writing of this abstract, we have confirmed 4 new (slow) pulsars. We present details of these confirmed pulsars as well as some of our top candidates.

We are also searching for new pulsars in the globular clusters M5, M13, M15, M53, and NGC 6760. Each of these clusters already contains at least one known pulsar. The data were taken with the Caltech Baseband Recorder, allowing the use of fast sampling rates and coherent dedispersion. We describe preliminary results from these searches.
