Dynamical evolution of a bulge in an N-body model of the Milky Way [PDF]

EPJ Web of Conferences, 2012
The detailed dynamical structure of the bulge in the Milky Way is currently under debate. Although kinematics of the bulge stars can be well reproduced by a boxy-bulge, the possible existence of a small embedded classical bulge can not be ruled out.

The Complex Structure of the Bulge of M31 [PDF]

The Astrophysical Journal Supplement Series, 2023
The bulge of M31 is of interest regarding the nature of galactic bulges and how their structure relates to bulge formation mechanisms and their subsequent evolution.

Chemodynamical history of the Galactic Bulge [PDF]

Annual Review of Astronomy and Astrophysics, 2018
The Galactic Bulge can uniquely be studied from large samples of individual stars, and is therefore of prime importance for understanding the stellar population structure of bulges in general.

The X-shaped Bulge of the Milky Way revealed by WISE [PDF]

, 2016
The Milky Way bulge has a boxy/peanut morphology and an X-shaped structure. This X-shape has been revealed by the `split in the red clump' from star counts along the line of sight toward the bulge, measured from photometric surveys. This boxy, X-shaped bulge morphology is not unique to the Milky Way and such bulges are observed in other barred spiral ...

Natures of a clump-origin bulge: a pseudobulge-like but old metal-rich bulge [PDF]

, 2011
Bulges in spiral galaxies have been supposed to be classified into two types: classical bulges or pseudobulges. Classical bulges are thought to form by galactic merger with bursty star formation, whereas pseudobulges are suggested to form by secular evolution due to spiral arms and a barred structure funneling gas into the galactic centre.

Made-to-Measure models of the Galactic Box/Peanut bulge: stellar and total mass in the bulge region [PDF]

, 2015
We construct dynamical models of the Milky Way's Box/Peanut (B/P) bulge, using the recently measured 3D density of Red Clump Giants (RCGs) as well as kinematic data from the BRAVA survey.

The black hole mass-bulge mass correlation: bulges versus pseudo-bulges [PDF]

arXiv, 2009
We investigate the scaling relations between the supermassive black holes mass (M_bh) and the host bulge mass in elliptical galaxies, classical bulges, and pseudo-bulges. We use two-dimensional image analysis software BUDDA to obtain the structural parameters of 57 galaxies with dynamical M_bh measurement, and determine the bulge K-band luminosities ...

Applicability of the Bulge Equations in plane strain bulge experiments [PDF]

EPJ Web of Conferences, 2010
The bulge equations are based on the assumption that the membrane deflects to an ideal cylindrical shape. But for low stresses and/or thick films the membrane is better described with a Double Clamped Plate (DCP) solution. The goal is then to assess when the bulge test experiment can accurately be described with an ideal cylindrical shape. Furthermore,
