X-RAY OBSERVATION OF THE WATER MEGAMASER GALAXY IC 2560

We propose a moderately long (80 ksec) observation of IC 2560, a Seyfert 2galaxy with a luminous water megamaser that shows many similarities to thearchtypical megamaser NGC 4258. IC 2560 is likely to be a key object for ourunderstanding of accretion disks around supermassive black holes. A briefChandra observation showed that the Xray source is hidden behind Comptonthickobscuration, with an extremely strong (EW 3.6 keV) Fe K alpha line. Ourobservation will collect approximately 10,000 source photons, allowing us toobtain a highquality spectrum of the central source, which will be used todetermine the source parameters, search for a Compton shoulder on the Fe K alphaline, and obtain a vastly improved spectrum of the soft Xray emission. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
