The type Ia supernova SNLS-03D3bb from a super-Chandrasekhar-mass white dwarf star
D. Andrew Howell, Mark Sullivan, Peter E. Nugent +14
The acceleration of the expansion of the universe, and the need for Dark Energy, were inferred from the observations of Type Ia supernovae (SNe Ia). There is consensus that SNe Ia…
Substructure in the Andromeda Galaxy Globular Cluster System
K. M. Perrett, D. A. Stiff, D. A. Hanes +1
In the most prominent current scenario of galaxy formation, galaxies form hierarchically through the merger of smaller systems. Such mergers could leave behind dynamical signatures…
Disk-Bulge-Halo Models for the Andromeda Galaxy
Lawrence M. Widrow, Kathryn M. Perrett, Sherry H. Suyu
We present a suite of semi-analytic disk-bulge-halo models for the Andromeda galaxy (M31) which satisfy three fundamental conditions: (1) internal self-consistency; (2) consistency…
New Mass Estimators for Tracer Populations
N. W. Evans, M. I. Wilkinson, K. M. Perrett +1
We introduce the tracer mass estimator. This is a new and simple way to estimate the enclosed mass from the projected positions and line of sight velocities of a tracer population…
The Kinematics and Metallicity of the M31 Globular Cluster System
K. M. Perrett, T. J. Bridges, D. A. Hanes +5
With the ultimate aim of distinguishing between various models describing the formation of galaxy halos (e.g. radial or multi-phase collapse, random mergers), we have completed a s…
The `remarkable' M31 globular cluster 037-B327 revisited
Pauline Barmby, Kathryn M. Perrett, Terry J. Bridges
The M31 globular cluster candidate 037-B327 has long been known to be an extremely red, non-stellar object. The first published spectrum of this object is used to confirm that it i…
