Structure and Evolution of Disk Galaxies in the GOODS Fields
Non-axisymmetric features (such as bars and spirals) as well as general triaxialities (such as those of the bulge and halo) drive the dynamical and secular...
Structure and evolution of star-forming gas in late-type spiral galaxies
We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628. We investigate the role of the...
Structure and stellar populations in early-type galaxies
We explore possible correlations between the light profile shapes of early-type galaxies, as parameterized by the Sérsic index n, and relevant stellar...
Structure of a simple sunspot from the inversion of IR spectral data
Analysis of spectral data of two neighboring infrared lines, Fe i 15648.5 Å (g = 3) and Fe i 15652.9 Å (g_eff = 1.53) are carried out for a simple sunspot when...
Structure of interacting elliptical radio galaxies
We have used a numerical method based on elliptical fitting of isophotes to analyze the structural parameters of three pairs of elliptical galaxies containing...
We describe the latest results and future prospects of the QUEST survey for RR Lyrae stars in the halo of the Milky Way. Because RR Lyrae variables are...
