Title NGC 4190-ULX1: The nearest unstudied ultraluminous X-ray source


DOI 10.5270/esa-8ygcrze
Author Mr Floyd Jackson
Description Although it ranks amongst the nearest (at d ~ 3 Mpc) and brightest (flux ~ 4e-12 erg-cm^2-s) ULXs, NGC 4190-ULX1 has not yet been studied in the modern era of X-ray astronomy. Here we propose two 25-ks XMM-Newton observations to provide a first detailed view of it.s X-ray properties. We will investigate the specific characteristics of the X-ray spectral and temporal data of the source, and contrast them with other low-luminosity (~10^39 erg-s) ULXs to provide new insights into this hitherto neglected class of objects.

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.
