The Spitzer Survey of Stellar Structure in Galaxies (S^4G)
Kartik Sheth, Michael Regan, Joannah L. Hinz +35
The Spitzer Survey of Stellar Structure in Galaxies S^4G is an Exploration Science Legacy Program approved for the Spitzer post-cryogenic mission. It is a volume-, magnitude-, and…
Mid-Infrared Galaxy Morphology from the Spitzer Survey of Stellar Structure in Galaxies (S^4G): The Imprint of the de Vaucouleurs Revised Hubble-Sandage Classification System at 3.6 microns
R. Buta, K. Sheth, M. Regan +17
Spitzer Space Telescope Infrared Array Camera (IRAC) imaging provides an opportunity to study all known morphological types of galaxies in the mid-IR at a depth significantly bette…
The complex interplay of dust and star light in spiral galaxy discs
Maarten Baes, Dimitri Gadotti, Joris Verstappen +4
Interstellar dust grains efficiently absorb and scatter UV and optical radiation in galaxies, and therefore can significantly affect the apparent structure of spiral galaxies. We d…
Secular Evolution and Structural Properties of Stellar Bars in Galaxies
Dimitri A. Gadotti
I present results from the modeling of stellar bars in nearly 300 barred galaxies in the local universe through parametric multi-component multi-band image fitting. The surface bri…
Do Nuclear Star Clusters and Supermassive Black Holes Follow the Same Host-Galaxy Correlations?
Peter Erwin, Dimitri Gadotti
Recent studies have suggested a strong correlation between the masses of nuclear star clusters and their host galaxies, an extension of the known correlations between supermassive…
Radiative transfer in disc galaxies IV - The effects of dust attenuation on bulge and disc structural parameters
Dimitri A. Gadotti, Maarten Baes, Sarah Falony
Combining Monte Carlo radiative transfer simulations and accurate 2D bulge/disc decompositions, we present a new study to investigate the effects of dust attenuation on the apparen…
