Beyond the Best-fit Parameter: New Insight on Galaxy Structure Decomposition From GALPHAT
Galaxy GALPHAT
2014/12/23
We introduce a novel image decomposition package, Galphat, that provides robust estimates of galaxy surface brightness profiles using Bayesian Markov Chain Monte Carlo. The Galphat-determined posterio...
Measurement of Galactic Logarithmic Spiral Arm Pitch Angle Using Two-Dimensional Fast Fourier Transform Decomposition
Galactic Logarithmic Spiral Arm Pitch Angle Two-Dimensional Fast Fourier Transform Decomposition
2012/2/23
A logarithmic spiral is a prominent feature appearing in a majority of observed galaxies. This feature has long been associated with the traditional Hubble classification scheme, but historical quotes...
