| Abstract | The large number of radio-quiet thermally emitting isolated neutron stars (INSs)in our local volume suggests that they belong to a neglected component of thepopulation. Only two such INSs are known at larger distances. We propose toinvestigate INS candidates from the 4XMM-DR9 catalogue to assess their long-termX-ray emission and improve spectral determination and localisation for follow-upstudies. Our program will explore a more remote and better characterised samplethan that detectable in the eROSITA All-Sky Survey. This fulfil proposal wasaccepted in AO20 and AO21 (IDs 088419, 090126; Pires et al. 2022). The twoobserved targets show remarkably soft and constant properties and highX-ray-to-optical flux ratios: results that validate our strategy to discover INSs beyond the solar vicinity. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
