Neutral Hydrogen Survey of Andromeda Galaxy

Science, 1966
A neutral hydrogen survey of the Andromeda galaxy (M31) has been conducted with the 260-foot (80m) Ohio State University radio telescope. The neutral hydrogen is concentrated in the spiral arm regions, with but relatively small amounts near the center of the galaxy.

AGAPE, Andromeda galaxy and amplified pixels experiment

Nuclear Physics B - Proceedings Supplements, 1995
The galaxy M31 is a very good potential target for microlensing searches. However, only few stars are resolved, and a different method is therefore needed : monitor pixels and not stars. This method, and the AGAPE project based on it, are presented here.

Radio Map of the Andromeda Galaxy

Science, 1964
The University of Illinois radio telescope has resolved the 610.5 Mcy/sec disk component of radio emission from the large galaxy M 31 into several discrete concentrations. In two cases, these correspond to the crossing of the optical major axis by spiral arms. A spur of emission extends southeast from the galaxy near the minor axis.

Methanol Masers in the Andromeda Galaxy

Proceedings of the International Astronomical Union, 2017
AbstractIs M31 going to collide with the Milky Way, or spiral around it? Determining the gravitational potential in the Local Group has been a challenge since it requires 3D space velocities and orbits of the members, and most objects have only had line-of-sight velocities measured. Compared to the less massive group members, the transverse velocity of

October: The Andromeda Galaxy

2015
October is a great month for stargazing on a grand scale, for this month the Andromeda galaxy slides into prime position. This, our nearest major galaxy, is just waiting to be discovered and installed at number one in your list of favorite stargazing objects.

The Wonder of the Andromeda Galaxy

2012
Who we are as humans is often dependent upon how we define our position in the universe. At the center of that definition since ancient times has been the Andromeda Galaxy. The astronomical story of the Andromeda Galaxy is not simply the tale of a celestial object, a specific tool such as the telescope, or of a particular science.

Star Formation in the Andromeda Galaxy

1988
An overview is given of the star formation characteristics of the Andromeda galaxy, as derived from various surveys of the Population I material. Particular attention is given to the analysis of infrared data. The contribution to the infrared emission of dust in diffuse HI clouds, heated by the interstellar radiation field, is significant. Observations
