NGC 1097 is a nearby SBb galaxy with a Seyfert nucleus and a bright starburst ring. We study the physical properties of the interstellar medium (ISM) in the ring using spatially resolved far-infrared spectral maps of the circumnuclear starburst ring of NGC 1097, obtained with the PACS spectrometer on board the Herschel Space Observatory. ... We observe evidence of rapid rotation in the circumnuclear ring, with a rotation velocity of ~220 km s-1 (inclination uncorrected) measured in all lines. ...
... Any object with either a raw count-rate > 60 or flagged as having a mod-8 pattern is considered to have produced a smoke-ring - any other source within or near to the smoke-ring is flagged. ... Compute the radial distance of the star (xstar, ystar) from the centre of the OM field of view (xCentre=1024.5, yCentre=1024.5) . ... Any source within a radius of 38 pixels is then flagged (the 38 was derived from an average radius of 26 + 12 photometry radius). ...

... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...
