Bulge Globular Clusters in Spiral Galaxies
The Astrophysical Journal, 2001 There is now strong evidence that the metal-rich globular clusters (GCs) near the center of our Galaxy are associated with the Galactic bulge rather than the disk as previously thought. Here we extend the concept of bulge GCs to the GC systems of nearby spiral galaxies.

A connection between bulge properties and the bimodality of galaxies [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe global colors and structure of galaxies have recently been shown to follow bimodal distributions. Galaxies separate into a “red sequence”, populated prototypically by early-type galaxies, and a “blue cloud”, whose typical objects are late-type disk galaxies. Intermediate-type (Sa-Sbc) galaxies populate both regions.

An Investigation into the Prominence of Spiral Galaxy Bulges [PDF]
The Astronomical Journal, 2001 From a diameter-limited sample of 86 `face-on' spiral galaxies, the bulge-to-disk size and luminosity ratios, and other quantitative measurements for the prominence of the bulge are derived. The bulge and disk parameters have been estimated using a seeing convolved Sersic r^(1/n) bulge and a seeing convolved exponential disk.

The Intrinsic Shape of Galaxy Bulges [PDF]
, 2016 The knowledge of the intrinsic three-dimensional (3D) structure of galaxy components provides crucial information about the physical processes driving their formation and evolution. In this paper I discuss the main developments and results in the quest to better understand the 3D shape of galaxy bulges.

The Formation of Galaxy Disks and Bulges [PDF]
Symposium - International Astronomical Union, 1999 Using a TREESPH code modified to run on a parallel computer and a new algorithm for modeling star formation, we have investigated the formation of disk galaxies from idealized cosmological perturbations.

The SAMI Galaxy Survey: decomposed stellar kinematics of galaxy bulges and disks [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We investigate the stellar kinematics of the bulge and disk components in 826 galaxies with a wide range of morphology from the Sydney-AAO Multi-object Integral-field spectroscopy Galaxy Survey. The spatially resolved rotation velocity (V) and velocity dispersion (σ) of bulge and disk components have been simultaneously ...

Galaxy bulges at mid- and high-redshift [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractBulges are a major galaxy component in the nearby universe, and are one of the primary features that differentiates and defines galaxies. The origin of bulges can be directly probed in part by examining distant galaxies to search for high redshift bulges, and to study the properties of bulges in formation.

A SAURON look at galaxy bulges
Astronomische Nachrichten, 2004 AbstractKinematic and population studies show that bulges are generally rotationally flattened systems similar to lowluminosity ellipticals. However, observations with state‐of‐the‐art integral field spectrographs, such as SAURON, indicate that the situation is much more complex, and allow us to investigate phenomena such as triaxiality, kinematic ...
