The baryonic tully-fisher relationship for S4G galaxies and the "condensed" baryon fraction of galaxies
Mizusawa, Trisha F.; Zaritsky, Dennis; Courtois, Hélène M.; Muñoz-Mateos, Juan Carlos; Sorce, Jenny G.; Erroz-Ferrer, Santiago; Comerón, Sébastien; Gadotti, Dimitri Alexei; Gil De Paz, Armando; Hinz, Joannah L. (2014-05-02)We combine data from the Spitzer Survey for Stellar Structure in Galaxies, a recently calibrated empirical stellar mass estimator from Eskew et al., and an extensive database of H I spectral line profiles to examine the ... -
The mass profile and shape of bars in the spitzer survey of stellar structure in galaxies (S⁴G): Search for an age indicator for bars
Kim, Taehyun; Sheth, Kartik; Gadotti, Dimitri Alexei; Lee, Myung Gyoon; Zaritsky, Dennis; Elmegreen, Bruce G.; Athanassoula, Evangelia; Bosma, Albert; Holwerda, Benne; Mizusawa, Trisha (2015-01-20)We have measured the radial light profiles and global shapes of bars using two-dimensional 3.6μm image decompositions for 144 face-on barred galaxies from the Spitzer Survey of Stellar Structure in Galaxies. The bar ... -
THE SPITZER SURVEY of STELLAR STRUCTURE in GALAXIES (S4G): MULTI-COMPONENT DECOMPOSITION STRATEGIES and DATA RELEASE
Salo, Heikki J.; Laurikainen, Eija; Laine, Jarkko; Comerón, Sébastien; Gadotti, Dimitri Alexei; Buta, Ronald J.; Sheth, Kartik; Zaritsky, Dennis; Ho, Luis; Mizusawa, Trisha (2015-07-20)The Spitzer Survey of Stellar Structure in Galaxies (S4G) is a deep 3.6 and 4.5 μm imaging survey of 2352 nearby (<40 Mpc) galaxies. We describe the S4G data analysis pipeline 4, which is dedicated to two-dimensional ... -
Unveiling the structure of barred galaxies at 3.6 mu;m with the spitzer survey of stellar structure in galaxies (S4G). I. Disk breaks
Mizusawa, Trisha F.; Kim, Taehyun; Gadotti, Dimitri Alexei; Sheth, Kartik; Athanassoula, E.; Bosma, Albert; Madore, Barry F.; Elmegreen, Bruce G.; Knapen, Johan H.; Lee, Myung Gyoon (2014-01-28)We have performed two-dimensional multicomponent decomposition of 144 local barred spiral galaxies using 3.6 μm images from the Spitzer Survey of Stellar Structure in Galaxies. Our model fit includes up to four components ...
