How Environment Shapes Low-Mass Galaxy Evolution, We’re on the verge of an observational revolution, with upcoming surveys like Rubin’s LSST and the Roman Space Telescope poised to uncover hundreds, if not thousands, of previously undetectable low-mass galaxies across a wide range of environments. To fully leverage this data, we need a clear theoretical framework for how environment shapes the evolution of these systems. In this talk, I present simulation-based work exploring how environmental processes influence observable properties of low-mass galaxies, including their sizes, star formation timescales, morphological asymmetries, and quenched fractions. Using a combination of large-volume and high-resolution cosmological simulations, I show how these galaxies carry structural and evolutionary imprints of their surroundings. I also highlight recent results comparing simulated satellite populations to observations from SAGA and ELVES, demonstrating how well current simulations reproduce observed trends in…

Title: After 20+ years, LSST is starting! Abstract: , The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will be the most, comprehensive optical astronomical sky survey ever undertaken. It will deliver panoramic, images of the night sky every clear night for ten years, starting in a few weeks. The resulting, few tens of petabytes of imaging data, essentially a digital color movie of the night sky, will, include about 20 billion galaxies and a similar number of stars. This unprecedented dataset, will be used for investigations ranging from cataloging potentially dangerous near-Earth, asteroids to fundamental physics such as the characterization of dark matter and dark energy. I will describe scientific goals behind LSST, discuss a major role played by the University, of Washington in the development of this project, showcase its early data, and discuss how, you can prepare to partake in the rich scientific harvest to be enabled by the massive and, complex LSST dataset.

Theodore Jacobsen Observatory Open House
Welcome
Welcome to the web page of the public events program at the Theodor Jacobsen Observatory (TJO) of the University of Washington. Come and join us for open houses where we offer a view through our 1895 telescope on clear dark nights. In addition, enjoy evening talks and other activities during your visit for people of all ages, from 6 to 100. Tickets are free.
Programs normally take place at the observatory on the first and third Tuesday evenings of April through September, rain or shine. The staff are entirely volunteers, including undergraduates from the “League of Astronomers” within the Astronomy Department as well as members of the Seattle Astronomical Society (under the auspices of the UW Astronomy Department).
TJO Evening Public Events
Sky viewing is the main event of the evening. However, nightfall comes late. So doors open at 8 or 9 PM from April through September (see below for dates and times) while the sky is still light. The first major event of the evening is a public talk by students…
