Millisecond pulsar searches in unidentified Fermi sources at high Galactic lati-

tudes
ABSTRACT: The Large Area Telescope (LAT) on the Fermi Gamma-Ray Space Telescope is revolutionizing the study of the high-energy sky and of pulsars. Fermi-LAT has identified more than 100 pulsars, including the new class of gamma-ray-emitting millisecond pulsars (MSPs). Many of these MSPs (which include exotic eclipsing binaries as well as very bright radio pulsars that are being added to gravitational wave timing arrays) are being discovered worldwide in radio searches of unidentified LAT sources located at high Galactic latitudes. At Arecibo we propose to survey 28 well-selected high-latitude unidentified sources from the 2nd Fermi source catalog (2FGL). We will search for MSPs in these targets at a frequency of 327 MHz, observing each source four times to counter the effects of scintillation, eclipses, and orbital acceleration, which otherwise demonstrably diminish the chance to detect existing MSPs in such systems. Our survey will be the most sensitive such work done anywhere.

Remote Observing Request

Observer will travel to AO X Remote Observing In Absentia (instructions to operator)

Section I I - Time Request
The following times are in LST.

Begin End IntervalInterval 00:15 05:30 12:00 12:30 15:45 18:30 19:00 22:00

Days Needed at This Interval 4 4 4 4

Time Constraints (Must Be Justified in the Prop osal Text) Each of 28 ob jects is being observed 4 times. We've gathered them into as few sessions as possible, to minimize overheads (but if desired they could be broken up further). The 3 sets of long sessions have precise start/stop LSTs, while the half-hour session can be scheduled anywhere between 11:30-1300 LST. A session at a given LST range should be separated from another session at the same LST range by at least one week.

Section I I I - Instruments Needed
327 Atmospheric Observation Instruments:

Sp ecial Equipment or setup: We can use the Mock spectrometers, but prefer PUPPI in 100 MHz mode if available, which we will use in shared-risk mode (one of us, Scott Ransom, is a PUPPI developer). We will provide disks to quickly stream data off Mock/PUPPI.
