Thick disk and pseudobulge formation in a clump cluster
EPJ Web of Conferences, 2012 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 ...

X-ray Insight into High-Energy Processes in Extreme Galactic Nuclear Environment
Universe, 2022 Nuclear regions of galaxies apparently play a disproportionately large role in regulating their formation and evolution. How this regulation works, however, remains very uncertain.

IS THE GALACTIC BULGE DEVOID OF PLANETS? [PDF]
The Astrophysical Journal, 2016 ABSTRACT We consider a sample of 31 exoplanetary systems detected by gravitational microlensing and investigate whether or not the estimated distances to these systems conform to the Galactic distribution of planets expected from models.

Microlensing Towards the Galactic Bulge [PDF]
Symposium - International Astronomical Union, 1993 We describe an ongoing survey to search for dark matter via lensing events of stars in the Galactic Bulge. The principal properties of the survey are described, and some preliminary results are shown for newly-discovered variables. We discuss some of the projects related to the study of the Galactic Bulge that can be addressed using these data, and ...

Prediction of Planet Yields by the PRime-focus Infrared Microlensing Experiment Microlensing Survey
The Astronomical Journal, 2023 The PRime-focus Infrared Microlensing Experiment (PRIME) will be the first to conduct a dedicated near-infrared microlensing survey by using a 1.8 m telescope with a wide field of view of 1.45 deg ^2 at the South African Astronomical Observatory.

The 3D Structure of the Galactic Bulge [PDF]
Publications of the Astronomical Society of Australia, 2016 AbstractWe review the observational evidences concerning the three-dimensional structure of the Galactic bulge. Although the inner few kpc of our Galaxy are normally referred to asthe bulge, all the observations demonstrate that this region is dominated by a bar, i.e., the bulge is a bar.

Astronomy & AstrophysicsContext. Although many globular clusters (GCs) have been identified in the Galaxy, their population is estimated to be incomplete, especially in regions with significant crowding and/or interstellar extinction, such as the Galactic bulge and plane.

Study of the Galactic Bulge Using New Planetary Nebulae Discovered on the AAO/UKST Hα Survey
, 2005 The AAO/UKST Halpha survey is revealing a substantial new population of Planetary Nebulae (PNe) over the southern Galactic Plane including ~550 in the Bulge. Such objects are excellent tracers for Bulge dynamical studies, are less affected by metallicity
