Although it ranks amongst the nearest (at d virgul 3 Mpc) and brightest (flux virgul 4e-12erg/cm^2/s) ULXs, NGC 4190-ULX1 has not yet been studied in the modern era ofX-ray astronomy. Here we propose two 25-ks XMM-Newton observations to provide afirst detailed view of it.s X-ray properties. We will investigate the specificcharacteristics of the X-ray spectral and temporal data of the source, andcontrast them with other low-luminosity (virgul10^39 erg/s) ULXs to provide newinsights into this hitherto neglected class of objects.

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.
