| Abstract | We propose to make a 120 ks XMM-Newton observation coordinated with NuSTAR ofthe little known NLS1, IGR J19378-0617, in order to probe a broad range ofvariability timescales in this extremely bright, low-mass source. It has beenobserved with XMM-Newton for only 12 ks and is clearly detected in the BAT70-month catalog. Despite its short exposure, this source shows severalinteresting features that require further exploration, including a low-frequencycontinuum lag, even hints of high-frequency reverberation, and a low-ionizationwarm absorber in the RGS. It is also a hard X-ray source that will clearly bedetected by NuSTAR. Given its strong variability and high count rate, it haspotential to reveal time lags above 10 keV. |

| 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. |
