|Title||Observations of SN 1987A with H.E.S.S. and XMM-Newton following a hint of recent|
|Author||Dr Denys Malyshev|
|Description||Our analysis indicates a recent (2016-2018) enhancement of the GeV emission from the SN 1987A region seen with Fermi-LAT. The observed signal is characterized by a hard spectrum with a slope of 1.7+--0.2 and detected only at energies 1 GeV. Fermi-LAT data constrain the position of the signal within 0.15deg around SN 1987A which allows several other possibilities for the multiwavelength counterpart, including SN 1987A, 30 Dor C, the Honeycomb nebula, RX J0536.9-6913 and a new possible transient source. We ask for joint H.E.S.S.-XMM-Newton (50 h-30 ksec) multiwavelength observations of the region in order to clarify the nature of the observed signal.|

|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.
