| Description | The detection of pulsating ultraluminous X-ray sources (PULXs) has led to a paradigm shift for the field; the key questions now revolve around the demographics of ULXs (black holes vs neutron stars) and the details of their accretion physics. The detection of more PULXs is critical to answering both questions. We have therefore mined the first eROSITA all-sky survey (eRASS1) with the intention of finding new PULX candidates. Here, we propose a 30 ks observation of a new extreme ULX (L(X) > 10^40 erg/s) detected in each of eRASS1, 2 and 3 with a high enough flux to make sensitive accelerated pulsation searches very viable, and thus determine whether it is a PULX. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
