Research

My early research interests stemmed from the objects I studied during my thesis - Central Dominant Galaxies or Brightest Cluster Galaxies. These are the largest galaxies in the ... universe. They can be used to determine how galaxies form and evolve in the highest space densities - the rich cluster environment. e.g.

     

Mackie, G, Visvanathan, N. and Carter, D. 1990, " The stellar content of central dominant galaxies. I - CCD surface photometry", Astrophysical Journal Supplement Series, vol. 73, p637

Mackie, G. 1992, "The stellar content of central dominant galaxies. II - Colors of cD envelopes", Astrophysical Journal, vol. 400, p65

The natural extension to this work was to look at the evolution of galaxies that are undergoing interactions and/or mergers, using multiwavelength (i.e. X-ray, UV, optical, infrared, radio) data. e.g.

Mackie G. and Fabbiano G. 1998, "Evolution of gas and stars in the merger galaxy NGC 1316 (Fornax A)", Astronomical Journal, vol. 115, p514

I have also bravely ventured into stellar research and learnt a great deal about an accretion-powered millisecond pulsar,

Elebert, P. et al. 2008, "Optical photometry and spectroscopy of the accretion-powered millisecond pulsar HETE J1900.1 - 2455", Monthly Notices of the Royal Astronomical Society, vol. 383, p1581

and have also done research into astronomy education e.g.

Mackie, G. 2000, "STaRS: Space science Teaching and Resource Site", Publications of the Astronomical Society of Australia, 17 (2) p113

Whilst based in New Zealand I wrote about the role of new technologies

Mackie, G. 2001, "New Technologies: Their present and future role in New Zealand research and development", New Zealand Science Review, Aug. 2001

and I also have an interest in astronomy history. e.g.

Peterson, J. and Mackie, G. 2006, "A brief history of the Astrophysical research Consortium and the Apache Point Observatory", Journal of Astronomical History and Heritage, Vol. 9, No. 1, p109

and future astronomical observations e.g.

Graves, K. , Mackie, G., 2009. "Internet Telescopes: Capabilities and Benchmarks", Small Telescopes and Astronomical Research Ed. R.M. Genet, J.M. Johnson, V. Wallen, Collins Foundation Press.
