I have moved! New homepage https://homepages.dias.ie/jmackey/

From 1. January 2016 I have moved to the Dublin Institute for Advanced Studies. Please go to my new homepage for up-to-date information.

Welcome to my homepage! I am a postdoctoral researcher in astrophysics, investigating the effects of massive stars on their environment, using theoretical and computational models. I develop and maintain pion, a computer simulation code for modelling photoionisation and magnetohydrodynamics. pion is a distributed-memory parallel code, designed to work on supercomputers, and I use it for most of my research projects.
I am working in the group of Prof. Stefanie Walch at the I. Physikalisches Institut at the University of Cologne. My research is part-funded through the Deutsche Forschungsgemeinschaft (DFG) priority program 1573, Physics of the Interstellar Medium.

I have helped to co-supervise the PhD projects of:
Eagle nebula pillars From 2010-2015 I was a postdoctoral researcher at the Argelander-Institut für Astronomie (AIfA), working in the stellar astrophysics group led by Prof. Norbert Langer. At AIfA, I was an Argelander Fellow (2010-2011), then an Alexander von Humboldt Fellow (2011-2013), and subsequently a staff postdoc funded through our group's project, "Effects of Massive Stars on their Surroundings", supported by the Deutsche Forschungsgemeinschaft (DFG) priority program 1573, Physics of the Interstellar Medium.
Before I came to Bonn I studied at NUI Galway, did a Masters thesis at the Harvard-Smithsonian Center for Astrophysics with Martin White, also working with Volker Bromm and Lars Hernquist. I finally completed my PhD at the Dublin Institute for Advanced Studies, working with Andrew Lim and Tom Ray. For my thesis project, I used an early version of pion to investigate the formation and evolution of massive pillars of gas and dust such as the Eagle Nebula pillars (shown to the right). These pillars, also known as elephant trunks, are observed at the boundaries of H II regions and are often active sites of star formation.


2015.09.04 I have been awarded a Royal Society-Science Foundation Ireland University Research Fellowship to run from 2016-2020: see announcements from the Royal Society, SFI, and DIAS.

2015.08.27 New paper accepted for publication, about the circumstellar medium of the red supergiant star W26 in Westerlund 1: (link to paperarXiv:1508.07003ADS).

2015.07.27 The first StarBench paper is now accepted for publication, and a preprint is available on arXiv:1507.05621. The paper studies the D-type expansion of HII regions.

2015.03.01 I have moved to the I. Physikalisches Institut at the University of Cologne, from the Argelander-Institut für Astronomie (AIfA) at the University of Bonn.

2014.08.12 Our paper "Interacting supernovae from photoionization-confined shells around red supergiant stars" has just been published in Nature. Read more here!
