We describe a high-resolution, high-sensitivity CO(1-0) survey of a large fraction of the south-west star-forming "ring" 20 kpc in diameter in M31 made with the 14 m FCRAO telescope and its QUARRY receiver array. At the 45'' angular resolution of the telescope, the ring is resolved into giant complexes of molecular gas with typical sizes of a few ...

The Eleventh Marcel Grossmann Meeting, 2008
Pixel lensing is gravitational microlensing of unresolved stars. The main target explored up to now has been the nearby galaxy of Andromeda, M31. The scien- tific issues of interest are the search for dark matter in form of compact halo objects, the study of the characteristics of the luminous lens and source populations and the possibility of ...

The systemic velocity of M31, rotation and expansion velocities as functions of galactocentric distance have been derived from all data available on the radial velocity field of the Andromeda galaxy. The bending of the outer parts of the M31 disk has been considered.

Seven SNR have been detected in M 31. Their galactic distribution, evolutionary stage, and possible relation to nucleosynthesis are discussed.

The projected mass method of Bahcall and Tremaine has been used to derive the mass of the core of M31. From the observed radial velocities of 43 globular clusters, the mass interior to 30' is found to be MI = (9 ± 2) × 1010 Msun. For six clusters with 100' MI = (2.4 ± 1.2) × 1011 Msun. From the observed radial velocities of M32, M33, NGC 147, NGC 185,

Recent high resolution HI observations of M31 made with the Westerbork Synthesis Radio Telescope shed new light on the structure of the interstellar medium in a galaxy supposedly similar to the Milky Way. Many filaments, arcs, and shell-like structures are found delineating regions which are devoid of neutral hydrogen.

The structural properties of external galaxies may be investigated using a model to generate the predicted number of stars as a function of apparent magnitude in any field in the galaxy. An implementation of such a model is explained in detail and is then tested against observations of M31.
