Radio Map of the Andromeda Galaxy
Science, 1964The 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, 2017AbstractIs 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 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.

Gravitational Microlensing toward the Andromeda Galaxy
2006Aktuelle Forschungsergebnisse deuten darauf hin, dass das Universum insgesamt aus 72% Dunkler Energie, 23% nichtbaryonischer Materie und 4.5% baryonischer Materie besteht. Von dieser baryonischen Materie kann bisher nur ein neuntel sicher zugeordnet werden.

The Wonder of the Andromeda Galaxy
2012Who 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
1988An 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
