The hot stars in orbit around the M 31 central supermassive black hole: are they young or old?
Aims. The cluster of hot stars observed in orbit around the central black hole of M 31 has been interpreted as a 200 Myr starburst. The formation of a population of young stars in close proximity toExpand
The cluster of blue stars surrounding the M31 nuclear black hole
We obtained U{sub 330}- and B-band images of the M31 nucleus using the High Resolution Camera of the Advanced Camera for Surveys on board the Hubble Space Telescope (HST). The spatial resolution inExpand
An STIS Atlas of Ca II Triplet Absorption Line Kinematics in Galactic Nuclei
The relations observed between supermassive black holes and their host galaxies suggest a fundamental link in the processes that cause these two objects to evolve. A more comprehensive understandingExpand
The stellar mass spectrum in warm and dusty gas: deviations from Salpeter in the Galactic centre and in circumnuclear starburst regions
Understanding the origin of stellar masses is a key problem in astrophysics. In the solar neighbourhood, the mass distribution of stars follows a seemingly universal pattern. In the centre of theExpand
Do Nuclear Star Clusters and Supermassive Black Holes Follow the Same Host-Galaxy Correlations?
Studies have suggested that there is a strong correlation between the masses of nuclear star clusters (NSCs) and their host galaxies, a correlation which is said to be an extension of the well-knownExpand
Bursty stellar populations and obscured active galactic nuclei in galaxy bulges
We investigate trends between the recent star formation history and black hole growth in galaxy bulges in the Sloan Digital Sky Survey (SDSS). The galaxies lie at 0.01 60%) is contributed by bulgesExpand
The supermassive black hole and double nucleus of the core elliptical NGC 5419
We obtained adaptive-optics assisted SINFONI observations of the central regions of the giant elliptical galaxy NGC 5419 with a spatial resolution of 0.2 arcsec (approximate to 55 pc). NGC 5419 has aExpand
The nuclear stellar disc in Andromeda: a fossil from the era of black hole growth
The physics of angular momentum transport from galactic scales (∼10–100 pc) to much smaller radii is one of the outstanding problems in our understanding of the formation and evolution ofExpand
A Slowly Precessing Disk in the Nucleus of M31 as the Feeding Mechanism for a Central Starburst
We present a kinematic study of the nuclear stellar disk in M31 at infrared wavelengths using high spatial resolution integral field spectroscopy. The spatial resolution achieved, FWHM = 0."12 (0.45Expand

TLDR
