Community Open Dome Event 28th Sept – Galaxies in 3D

Thursday 28th September – 7pm

The Long Eaton Astronomical Society meetings are now known as “Community Open Dome Events” and the first of this academic year is nearly here. We are joined by Professor Alfonso Aragón-Salamanca, Head of the Astronomy group at the University of Nottingham. He was an undergraduate at the University of Madrid, and got his PhD from Durham University in 1991. He worked in Durham and Cambridge for a number of years, and moved to Nottingham in 1999. His research addresses how galaxies form and evolve in different environments over cosmic time.  The topic is “Galaxies in 3D”.


“In order to understand how galaxies form and evolve we need to get very detailed information with as much spatial and spectral resolution as we possibly can. A new exciting observational technique has been developed in the last few years called “Integral Field Spectroscopy” which allows us to dissect the light emitted by different regions of galaxies simultaneously, thus obtaining three-dimensional images for them. In this talk Prof. Aragón-Salamanca will describe this new technique, its applications, and some of the most interesting results that he is obtaining within the MaNGA project, part of the Sloan Digital Sky Survey. This work is answering key questions on the formation history of the different regions and components of thousands of galaxies.”

After the talk there will be opportunity to look around the observatory and if clear do some observing using one of the telescopes housed within. Admission is via a suggested donation of £2 towards costs and includes refreshments. Talk starts at 7pm with refreshments available from 6:30pm. The event will close approx. 9pm. Under 16’s must be accompanied by an adult please.
