This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).
The Galaxy And Mass Assembly (GAMA) survey is currently a 144 square-degree multi-wavelength survey including optical spectra being collected at the Anglo-Australian Telescope (AAT).
Type Ia supernovae (SNe Ia) are the best cosmological yard sticks available. Measurements of nearby and distant SNe Ia led to the discovery of the accelerating universe and currently provide the best constraints on the nature of dark energy.
Chemical abundances in galaxies provide a fossil record of previous generations of star formation, modulated by galactic-scale gas flows. I will present the latest results from our investigation into the chemical evolution of galaxies, both locally, and at high redshift.
Observations of the structure and kinematics of different stellar populations in the Milky Way's disk provide a unique perspective on disk formation and evolution.
There are only good reasons to study dwarf galaxies: because small is beautiful, because many are known but many are still being looked for, because they are more complex and varied than the classical idiom "building blocks" would suggest, etc. Combining rich
A galaxy’s Spectral Energy Distribution (SED) contains information about its physical properties, such as redshift, stellar population age, mass, star formation rate, dust content, and metallicity.
Much has been learned about exoplanet atmospheres in recent years.
Extra-Solar Planets via Bayesian Model Fitting ABSTRACT: Recent advances in astronomy have yielded a rich harvest of over 600 exoplanets including the detection of a super earth in the habitable zone surrounding Gliese 581.This and other remarkable successes on the part of the observers is motiva
