Feb 27 3:00 p.m. RLM 5.104	SPECIAL COLLOQUIUM Kristen McQuinn The University of Texas at Austin	Low-Mass Galaxies: Windows into Galaxy Formation and Evolution Dwarf galaxies in the nearby universe give us an unparalleled view into galaxy evolution and, due to their low-masses, provide stringent tests for hydrodynamical simulation predictions of the baryon cycle. For decades, we have studied the resolved individual components of dwarfs - including their stars, gas, chemical compositions, and dust - to understand different aspects of their formation history. Now, we are on the cusp of bringing these pieces together into an integrated stellar and chemical history across cosmic timescales. By combining observations from multiple space and ground based flagship telescopes, I will outline a path towards measuring the star formation histories, stellar feedback energetics, and gas properties of low-mass galaxies, tracking the distribution of their elements across their stars, gas, and into their circumgalactic medium. I will also highlight the role future missions such as GMT, JWST, WFIRST, and the SKA path finders will play at the frontier of nearby galaxy research. close
