Cloudy Workshop 2017

Queen's University Belfast: 31 July - 4 August 2017

We are pleased to announce the Cloudy Workshop 2017, which will be held in the School of Mathematics and Physics at Queen's University Belfast.

The Workshop will be delivered by Prof Gary Ferland of the University of Kentucky, the creator of Cloudy.

This will be a good opportunity for people in the UK, and indeed elsewhere in Europe, to attend a Cloudy Workshop at relatively low cost.

Nearly all of the quantitative information we have about the cosmos is the result of the analysis of spectra. We can directly measure the temperature, density, pressure or composition of a cloud of gas or a star, using a telescope and a spectrometer. This Workshop will go over some basics of spectroscopy, with an emphasis on emission-line regions such as star-forming regions, AGB stars, Active Galactic Nuclei and Starburst galaxies, and the intergalactic medium.

We will cover both the theory of diffuse non-LTE matter, quantitative spectroscopy (the science of using spectra to make physical measurements), and using Cloudy to understand an object and its spectrum. The sessions will consist of a mix of textbook study (using Osterbrock & Ferland, Astrophysics of Gaseous Nebulae and Active Galactic Nuclei), the application of the spectral-simulation code Cloudy to a variety of astrophysical problems, and projects organised by the participants.

Note that no prior experience with Cloudy is assumed. However, participants should have a reasonable knowledge of undergraduate-level spectroscopy and atomic physics.
