|Title||A MEASUREMENT OF THE 0.3-30 KEV SPECTRUM OF THE LOW-METALLICITY GALAXY VV114|
|Author||Dr Bret Lehmer|
|Description||We propose for a 30 ks XMM and 200 ks NuSTAR observation of VV114, a unique low-metallicity galaxy (0.3 Zsol), with high-SFR (SFR = 38 Msol-yr). We will measure ho the shape and normalization of the 0.3-30 keV spectral energy distribution of VV114 compares with more typical solar-metallicity galaxies in the nearby Universe that have SEDs characterized by NuSTAR (e.g., M83, NGC 253, NGC 3256, and NGC 3310). Our observations will provide an important benchmark for how the X-ray SED varies with metallicity, and thus how the X-ray SEDs of galaxies are expected to vary with redshift. This will allow for more informed bandpass and bolometric corrections to high-redshift galaxy studies and population synthesis models, and will inform studies of X-ray heating of the early Universe IGM.|

|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.
