| dc.description.abstract | An excess of γ-ray emission from the Galactic Center (GC) region with respect to predictions based on a variety of interstellar emission models and γ-ray source catalogs has been found by many groups using data from the {\it Fermi} Large Area Telescope (LAT). Several interpretations of this excess have been invoked. In this paper we search for members of an unresolved population of γ-ray pulsars located in the inner Galaxy that are predicted by the interpretation of the GC excess as being due to a population of such sources. We use cataloged LAT sources to derive criteria that efficiently select pulsars with very small contamination from blazars. We search for point sources in the inner 40∘×40∘ region of the Galaxy, derive a list of approximately 400 sources, and apply pulsar selection criteria to extract pulsar candidates among our source list. We performed the entire data analysis chain with two different interstellar emission models (IEMs), and found a total of 135 pulsar candidates, of which 66 were selected with both IEMs. | en_US |

We would like to thank Richard Bartels, Dan Hooper, Tim Linden, Siddhartha Mishra-Sharma, Nicholas Rodd, Benjamin Safdi and Tracy Slatyer for helping us to identify an error in the maximum likelihood analysis of the Galactic bulge and disk PSR populations that was included in a previous version of this paper, (arXiv:1705.00009, v1). Their work is described in a note will be posted on arXiv at the same time as this draft (Bartels et al. 2017). | en_US |
