Journal ArticleDOI
Structure and formation of elliptical and spheroidal galaxies
TL;DR: In this paper, surface photometry of all known elliptical galaxies in the Virgo cluster is combined with published data to derive composite profiles of brightness, ellipticity, position angle, isophote shape, and color over large radius ranges.
Journal ArticleDOI
The Structure of Classical Bulges and Pseudobulges: The Link Between Pseudobulges and Sérsic Index
David B. Fisher,Niv Drory +1 more
TL;DR: In this article, the authors studied the properties of pseudobulges and classical bulges in bulge-disk decompositions and found that the distribution of bulge Sersic indices, nb, is bimodal.
Journal ArticleDOI
Bulges of nearby galaxies with Spitzer: scaling relations in pseudobulges and classical bulges
David B. Fisher,Niv Drory +1 more
TL;DR: In this article, scaling relations of bulges using bulge-disk decompositions at 3.6?m were investigated for 173 E-Sd galaxies within 20?Mpc.
Journal ArticleDOI
Demographics of bulge types within 11 Mpc and implications for galaxy evolution
TL;DR: In this article, an inventory of galaxy bulge types (elliptical galaxy, classical bulge, pseudobulge, and bulgeless galaxy) in a volume-limited sample within the local 11mpc sphere using Spitzer 3.6 μm and Hubble Space Telescope data is presented.
Journal ArticleDOI
A Connection between Bulge Properties and the Bimodality of Galaxies
Niv Drory,David B. Fisher +1 more
TL;DR: In this paper, the authors identify classical bulges and pseudobulges morphologically with HST images in a sample of nearby galaxies and show that the red-blue dichotomy is a function of bulge type.
