We are saddened to learn that Dr. Loren Jacobson, who taught Physics 109 for almost a decade, has passed away over this winter break. We in the physics department extend our sincere condolences to his family, friends, and former students.
- The New Mexico Tech Physics Department has been ranked 39th by College Factual out of 263 schools for Physics! Read more about it here.

Star Formation in Crowds
Star formation changes with the environment and high mass stars define the neighborhood
Star formation is the defining process in the evolution of galaxies.
Our present understanding of star formation has primarily been informed by low-mass
stars in nearby clouds, but these nearby regions do not reflect typical
conditions over the history of the universe. The denser and more crowded
regions that likely represent our own origins exist within our own Galaxy, and
ALMA allows us to explore these regions in ways previously impossible. I will
show that high-density regions lead to the preferential formation of clusters over
isolated stars. n these dense, clustered regions, the stellar initial mass
function (IMF) is governed, and perhaps changed, by feedback from high-mass
stars. With the new ability to identify individual protostars in distant
regions, we can now directly measure how many stars are forming and determine
how the prerequisites for gas to collapse into stars change with the environment.
Finally, I will describe the recently-begun ALMA-IMF large program that will
expand these studies to a Galactic scale.
