A previous study showed that, while these MSPs are unresolved in gamma rays, some of them could have been detected in past X-ray observations. The authors also identified a large number of MSP candidates among unidentified X-ray sources. By analyzing unpublished radio images, we found interesting radio counterparts to 6 of those candidates, and were granted 20h of observations with the Green Bank Telescope to settle on their nature. We discovered two new MSPs, PSR J1740-2807 and PSR J1740-2805, towards one of our radio/X-ray targets, bringing to 4 the number of highly-dispersed MSPs in the GC direction and probably unveiling the first direct evidence of a bulge MSP population. We propose to carry out regular timing of these pulsar with Parkes, in order to reveal their properties and potentially claim association of PSR J1740-2807 with the original X-ray source. The follow up of these sources will have a major impact on our understanding of the Fermi GeV excess.", "num_resources": 0, "num_tags": 0, "organization": {"id": "aa2e8465-918a-44d1-aaab-34b7632fa3e5", "name": "csiro-data-access-portal", "title": "CSIRO Data Access Portal", "type": "organization", "description": "Harvester for CSIRO Data Access Portal", "image_url": "", "created": "2025-06-23T12:29:12.193044", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://data.csiro.au", "href": "https://data.csiro.au/collection/csiro:65098", "title": "CSIRO DAP"}, "owner_org": "aa2e8465-918a-44d1-aaab-34b7632fa3e5", "private": false, "promotion_level": "0", "spatial": "Australia", "state": "active", "temporal_coverage_from": "2000-01-01 00:00:00", "title": "Parkes observations for project P1317 semester 2024OCTS_06", "type": "dataset", "unpublished": false, "url": null, "version": null, "resources": [], "tags": [], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "extras": [{"key": "harvest_object_id", "value": "74139d6e-acd9-41a8-8d31-466a88012644"}, {"key": "harvest_source_id", "value": "74e2544e-7627-4cb4-b9ba-1d4a043af4f3"}, {"key": "harvest_source_title", "value": "CSIRO DAP"}]}}
