Results 31 to 40 of about 281 (182)
The Astrophysical Journal, 2023 We analyze H α or CO rotation curves extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy star formation ( z ∼ 0.6–2.5), more than doubling the previous sample ...

Overview of the Near-IR S0 Galaxy Survey (NIRS0S)
Advances in Astronomy, 2011 An overview of the results of the near-IR S0 galaxy survey (NIRS0S) is presented. NIRS0S is a magnitude- (mB⩽12.5 mag) and inclination- (

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.

Color dichotomy and gradients in the bulges and disks of EFIGI galaxies along the Hubble sequence
Astronomy & AstrophysicsContext. One of the most outstanding questions in contemporary astrophysics is: What is the significance of galaxy morphology? What physical processes underlie the morphologies we observe and is a galaxy’s internal structure shaping its evolution (nature)

The mass-metallicity relation of bulges
Astronomy & AstrophysicsContext. Bulges, located at the central regions of galaxies, are complex structures, expected to be shaped by the physical processes involved in the assembly history of their host galaxy, such as gravitational collapse, mergers, interactions, and bars ...

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 ...
