Mass modelling of early-type systems is a thorny issue; even for the few close by galaxies for which kinematic data are available, the implementation of this data can get embroiled in problems that are hard to overcome, unless more complete data sets are available. The mass-anisotropy degeneracy is a typical example of this. In this paper, we present a new mass modelling formalism for ellipticals that invokes no other observations other than the central velocity dispersion (σ 0 ) and photometry…

A new mass model describing motion in axially symmetric galaxies with dark matter

We present a new analytical model in order to describe motion in axially symmetric galaxies containing dark matter. The model has a finite mass and can describe motion in disc as well as in

Galaxy structure from multiple tracers - II. M87 from parsec to megaparsec scales

Following a number of discrepant studies of M87’s mass prole, we carry out an extensive dynamical analysis of multiple tracer populations in this giant elliptical galaxy in order to constrain its

Unveiling the Influence of Dark Matter in Axially Symmetric Galaxies

Abstract We investigate the regular or chaotic nature of orbits of stars moving in the meridional plane (R, z) of an axially symmetric galactic model with a dense, massive spherical nucleus and a

The corotation gap in the Galactic H i distribution

We used the H I data from the LAB Survey to map the ring-shaped gap in H I density that lies slightly outside the solar circle. Adopting R0 = 7.5 kpc, we find an average gap radius of 8.3 kpc and an

Total mass distributions of Sersic galaxies from photometry and central velocity dispersion

Aims. We develop a novel way of finding total mass density profiles in Sersic ellipticals, to about 3 times the major axis effective radius, using no other information other than what is typically



Dark Matter in Galaxies

Central DM density cuspiness in LSB's: a stellar kinematics approach. Abstract. We present preliminary results from spectroscopic observations of a sample of 11 low surface brightness galaxies (LSB).

Evidence in Virgo for the Universal Dark Matter Halo

A model is constructed for the mass and dynamics of M87 and the Virgo Cluster. Existing surface photometry of the galaxy, mass estimates from X-ray observations of the hot intracluster gas, and the

A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion

We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius. The result is based on a

Massive Elliptical Galaxies: From Cores to Halos

In the context of recent observational results that show massive ellipticals were in place at high redshifts, we reassess the status of monolithic collapse in a ΛCDM universe. Using a sample of over

A Nonparametric Estimate of the Mass of the Central Black Hole in the Galaxy

We estimate the mass of the central black hole in our Galaxy from stellar kinematic data published by Ghez et al. and Genzel et al. For this we develop a method, related to that presented by Merritt

The Ursa Major Cluster of Galaxies. V. H I Rotation Curve Shapes and the Tully-Fisher Relations

This paper investigates the statistical properties of the Tully-Fisher (TF) relations for a volume-limited complete sample of spiral galaxies in the nearby Ursa Major Cluster. The merits of B, R, I,

Mass-to-light ratio gradients in early-type galaxy haloes

Owing to the fact that the near future should see a rapidly expanding set of probes of the halo masses of individual early-type galaxies, we introduce a convenient parameter for character­ izing the

The Supermassive Black Hole of M87 and the Kinematics of Its Associated Gaseous Disk

We have obtained long-slit observations of the circumnuclear region of M87 at three different locations, with a spatial sampling of 0.″028 using the Faint Object Camera f/48 spectrograph on board

Dynamics of the Globular Cluster System Associated with M49 (NGC 4472): Cluster Orbital Properties and the Distribution of Dark Matter

Using the Low Resolution Imaging Spectrometer on the Keck I and II telescopes, we have measured radial velocities for 196 globular clusters (GCs) around M49 (NGC 4472), the brightest member of the

Dynamical Constraints on the Formation of NGC 4472 and Its Globular Clusters

We present new radial velocities for 87 globular clusters around the elliptical galaxy NGC 4472 and combine these with our previously published data to create a data set of velocities for 144
