We construct dynamical models of the "double" nucleus of M31 in which the nucleus consists of an eccentric disk of stars orbiting a central black hole. The principal approximation in these models is that the disk stars travel in a Keplerian potential; i.e., we neglect the mass of the disk relative to the black hole. We consider both "aligned" models, in which the eccentric disk lies in the plane of the large-scale M31 disk, and "nonaligned" models, in which the orientation of the eccentric disk…

Three-dimensional Keplerian orbit-superposition models of the nucleus of M31
We present three-dimensional eccentric disc models of the nucleus of M31, modelling the disc as a linear combination of thick rings of massless stars orbiting in the potential of a central black
Photometry and Kinematics of Self-gravitating Eccentric Nuclear Disks
The Andromeda galaxy hosts an elongated nucleus with (at least) two distinct brightness peaks. The double nucleus can be explained by the projection of a thick, apsidally aligned eccentric nuclear
Constraints on the Stellar Mass Function from Stellar Dynamics at the Galactic Center
We consider the dynamical evolution of a disk of stars orbiting a central black hole. In particular, we focus on the effect of the stellar mass function on the evolution of the disk, using both
THE BLACK HOLE MASS AND THE STELLAR RING IN NGC 3706
We determine the mass of the nuclear black hole (M) in NGC 3706, an early-type galaxy with a central surface brightness minimum arising from an apparent stellar ring, which is misaligned with respect
The Double Nucleus and Central Black Hole of M31
New spectroscopy of M31 supports Tremaine's model in which both nuclei are parts of a single eccentric disk of stars orbiting the black hole (BH). The kinematics and Hubble Space Telescope photometry
DISCOVERY OF AN Hα EMITTING DISK AROUND THE SUPERMASSIVE BLACK HOLE OF M31
Due to its proximity, the mass of the supermassive black hole in the nucleus of the Andromeda galaxy (M31), the most massive black hole in the Local Group of galaxies, has been measured by several
Dynamical modeling of the stellar nucleus of M 31
We present stellar dynamical models of the lopsided, double{peaked nucleus of M 31, derived from Hubble Space Telescope (HST) photometry. A Schwarzschild{type method, in conjunction with
The Pattern Speed of the Nuclear Disk of M31 Using a Variant of the Tremaine-Weinberg Method
The twin peaks in the nucleus of M31 have been interpreted by Tremaine as a thick, eccentric disk of stars orbiting a massive dark object; the required alignment of the apoapsides of the stellar
Molecular Gas around the Double Nucleus in M83
TLDR
High-velocity molecular gas associated with the visible off-center nucleus of M83 is discovered and a steep velocity gradient across it is found, attributed to a gas disk rotating around the off- center nucleus, which may be the remnant of a small galaxy accreted by M83.
A NEW SECULAR INSTABILITY OF ECCENTRIC STELLAR DISKS AROUND SUPERMASSIVE BLACK HOLES, WITH APPLICATION TO THE GALACTIC CENTER
We identify a new secular instability of eccentric stellar disks around supermassive black holes. We show that retrograde precession of the stellar orbits, due to the presence of a stellar cusp,
