Abstract: WISPs (WFC3 Infrared Spectroscopic Parallel survey) is a Hubble Space Telescope survey,which probes galaxy evolution with parallel infrared grism spectroscopy. This space-based survey covers a broad, continuous spectral range of 0.8--1.7 micron, over thousands of square minutes all over the sky.Over several years, WISPs has measured the redshifts of thousands of low-mass,metal-poor galaxies and galaxies with extreme star formation rates. I will review the progress of the WISP survey, and present scientific highlights, including the evolution of Halpha and [OIII] luminosity functions, the star formation main sequence, and special objects like metal poor dwarfs, z > 6 Lyman alpha emitters, and galaxy pairs. WISPs is the ideal pathfinder to the planning of next generation telescopes such as WFIRST, EUCLID and JWST.
Bio: Yu Sophia Dai(戴昱) is a Postdoctoral Researcher at California Institute of Technology-IPAC. She received her PhD in astrophysics in 2014,working on the observational study of dusty quasars, under the supervision of Dr. Giovanni Fazio from Harvard-Smithsonian Center for Astrophysics (CfA). Before moving to Cambridge, Massachusettes, she obtained her M.S degree in Physics from Boston College (2009), and a B.S.degree in physics from Beijing University (2007).Her research interests are the formation and evolution of galaxies, with a focus on active galactic nuclei (AGN) and the AGN - host connection from a multi-wavelength perspective. She is also an expert in infrared grism spectroscopic surveys. |
