New Tools for Galactic Archaeology from the Milky Way
Gail Zasowski, John Hopkins University
One of the critical components for understanding galaxy evolution is understanding the Milky Way Galaxy itself — its detailed structure and chemodynamical properties, as well as fundamental stellar physics, which we can only study in great detail locally. This field is currently undergoing a dramatic expansion towards the kinds of large-scale statistical analyses long used by the extragalactic and other communities, thanks in part to an enormous influx of data from space- and ground-based surveys. I will describe the Milky Way and Local Group in the context of general galaxy evolution and highlight some recent developments in Galactic astrophysics that take advantage of these big data sets and analysis techniques. In particular, I will focus on two diverse approaches: one to characterize the distribution and dynamics of the carbon-rich, dusty diffuse ISM, and one to map the resolved bulk stellar properties of the inner disk and bulge. The rapid progress in these areas promises to continue, with the arrival of data sets from missions like SDSS, Gaia, LSST, and WFIRST.
The Thirty Meter Telescope: The Next Generation Ground Based Optical/InfraRed Observatory
Dr. Warren Skidmore, Thirty Meter Telescope Corp.
Abstract: After a construction status update, I will describe how the telescope design was developed to support a broad range of observing capabilities and how the observatory is being engineered. I’ll discuss some of the observational capabilities that the Thirty Meter Telescope will provide and some of the areas of study that will benefit from the TMT’s capabilities, specifically synergistic areas with new and future proposed astronomical facilities. Finally I will describe the avenues through which astronomers can have some input in the planning of the project and potential NSF partnership, prioritizing the development of 2nd generation instruments and directing the scientific aims for the observatory.
The NMSU Department of Astronomy will hold an observatory open house at the NMSU campus observatory at 8 p.m.Friday, Sept. 9. Astronomy personnel on hand will be Chris Churchill and graduate assistants Xander Thelen, Trevor Picard and Jacob Vander Vliet.
Guests can view Mars and Saturn together in the evening sky in the constellation of Scorpio. Telescopes will also have the center of the Milky Way Galaxy in view, and in this region there are many beautiful star clusters and globular clusters (tight groups of millions of stars). High in the sky, viewers will see the constellation Vega with its double-double star system and the famous ring nebula, which is the remnants of a dying star much like our own sun. The moon will be in the phase called first quarter and will make a wonderful sight.
Contact the NMSU Astronomy Department at 575-646-4438 with questions. Everyone is welcome to come and spend an evening of stargazing. Admission is free and children are especially welcome to attend.
