    Abstract of Session/Presentation: With a growing demand for international collaboration among scientists in modern-day research to collectively answer questions about our universe, GLAS Education and Stone Edge Observatory (SEO) partnered with the WAROAD to create an intensive educational experience for astronomy teaching and public engagement. We leverage globular cluster (GC) studies as the perfect combination of entry-level astronomy and potential for discovery. GC's are among the most studied objects in our Milky Way and GC research has contributed to our understanding of the distribution and properties of dark matter, as well as what dynamic history their host galaxy underwent. However, this is still a very active area of research.

    Our project has introduced upcoming scientists with data analysis tools in astrophysics to observe, reduce, and analyze globular cluster data from SEO. Within our framework, each student is equipped to stack images using Jupyter notebooks, plot histograms, and statistics (mean, std), observe and download images using SEO, as well as leverage different filters for mosaicing, flux calibration, and data reduction (bias, darks, flats). In this presentation, we show some of our initial results. In particular, we will present the mosaics of our chosen globular cluster (M3), our data reduction process, and statistics of our data. We will also show preliminary color-magnitude (CMDs) and Hertzsprung-Russell (HR) diagrams of our globular clusters. We will also comment on future plans to characterize the properties (ages, metallicities, and colors) of the stellar populations in our clusters.

    Our project involved meeting online via Zoom, utilizing Slack to communicate and observe remotely, and performing analyses online using Jupyter notebooks / online tutorials on archival and current data from the SEO telescope. This framework encourages and supports cross-cultural collaboration.
