Astronomy and Astrophysics

Mt John Observatory

Astronomy is the oldest science, from ancient China and classical Greece through the Renaissance, where Copernicus, Kepler and Newton made huge contributions to our knowledge and understanding of the solar system and planetary motion.

But the science of astrophysics which seeks to explain the structure and evolution of the stars and other celestial objects by applying the principles of physics to interpret our observations, is little more than a century old.

The McLellan Telescope

Currently astronomy is undergoing huge expansion as we can now view the Universe at all wavelengths of the electromagnetic spectrum.

Satellites can get above the atmosphere to detect gamma rays and on the ground huge telescope arrays many kilometres across make exciting discoveries with radio waves. Electronic detectors, known as CCDs have replaced photography for optical observations in astronomy, and this data has led to new advances in our knowledge of the Universe.

Galaxy Evolution

  • UC astronomers are involved in several galaxy surveys, piecing together data from a wide range of wavelengths for large numbers of galaxies. The multi-wavelength coverage allows the measurement of important physical properties of the galaxies, and so tests models of galaxy formation and evolution. The surveys include the H-ATLAS, GAMA and several SKA pathfinder surveys.

Globular Clusters and Galactic Chemical Evolution

  • Observational and theoretical studies of star clusters and their influence on the evolution of galaxies. (Supported by Marsden Fund research grant Element enrichment through mergers and stellar nucleosynthesis, Cottrell & Albrow.)

Gravitational Microlensing

  • UC astronomers are members of two international collaborations involved in the detection and detailed study of gravitationally lensed stars to discover planets and dark matter. PLANET MOA

Astroseismology

  • In much the same way that seismologists use earthquakes to deduce the structure of our planet, UC astrophysicists study the internal structure of stars by measuring tiny motions on their surfaces. (Supported by Marsden Fund research grant The music of the stars: Internal structure revealed through the surface vibrations of stars, Pollard & Cottrell.)

Pulsating Stars

  • Pulsating low mass supergiant stars are the precursors of proto-planetary nebulae. UC astrophysicists use facilities at the Mt John Observatory to study the pulsations and the shock waves produced in these stars.

Optical Design

  • UC astrophysicists have designed sophisticated optics and instrumentation for a number of medium - large telescopes both in New Zealand and overseas.

General Relativity and Theoretical Cosmology

  • UC astrophysicists work on theories of fundamental structure, black holes and dark energy.

A career in astronomy might be as a university academic, or you might work in a government funded observatory or institute. Many astronomers are also employed by the major space agencies, such as NASA and ESA. Some are also employed in public outreach programmes, such as in planetaria. Astronomers have a broad training in many branches of physics as well as astronomy (such as optics, atomic physics, electronics, electromagnetism and radiophysics, nuclear physics, spectroscopy) and they are also skilled in computing and in image processing. All this means that students trained in astronomy are highly employable in many areas of science, technology or computing.
