| Description | We propose a 60ks observation for one new GeV bright nova to explore the particle acceleration and gamma-ray production mechanisms. We will constrain the particle acceleration efficiency by comparing thermal X-ray to GeV luminosity and search for predicted non-thermal X-rays. Understanding shocks in novae is r^ant for other shock-powered transients including Type IIn supernovae, tidal disruption events and stellar mergers. NuSTAR is the only instrument capable of detecting X-rays from novae simultaneously with the GeV emission (the lower energy X-rays accessible to other focusing instruments are hidden by the nova shell at these times). The observations should be conducted now to take advantage of the simultaneous operations with Fermi/LAT. |

| 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. |
