Supermassive black holes in galactic bulges [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract Growing evidence indicate supermassive black holes (SMBHs) in a mass range of MBH∼ 106–1010 M⊙ lurking in central stellar bulges of galaxies. Extensive observations reveal fairly tight power laws of MBH versus the mean stellar velocity dispersion σ of the host stellar bulge.

Infrared Scanning of the Galactic Bulge [PDF]
Symposium - International Astronomical Union, 1985 We find values of the interstellar absorption from J, H and K scans of a 6.8 × 200 arcmin strip of sky extending from the Sgr I field to the Galactic Centre. The visual absorption, excluding dark clouds, increases from 3 to 30 magnitudes in this region.

SciPost Physics Proceedings, 2023 After more than a decade since its discovery, the Galactic center gamma-ray excess - discovered with the Fermi Large Area Telescope - remains puzzling. While the spectrum of the signal can be explained by either dark matter or an unresolved population of

The Astrophysical Journal Supplement Series, 2023 The Nancy Grace Roman Space Telescope (Roman) is NASA’s next astrophysics flagship mission, expected to launch in late 2026. As one of Roman’s core community science surveys, the Galactic Bulge Time Domain Survey (GBTDS) will collect photometric and ...

The Astrophysical JournalWe report the first high-resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within 1° of the Galactic plane, where high extinction has rendered such studies challenging. Our high-signal-to-noise-ratio and high-resolution,

Symposium - International Astronomical Union, 1998 I review current work on the Galactic bulge, with emphasis on issues that may connect to the environment of the Galactic Center. There is growing evidence that the field population of the bulge at RGC > 500pc is as old as the metal rich Galactic center globular clusters, and that field and clusters have the same spatial and metallicity distribution.
