Heidi Jo Newberg
Associate Professor of Physics, Applied Physics, and Astronomy
Education:
Ph.D., University of California, Berkley.
Career Highlights:
Newberg has worked in many areas of astronomy over the course of her career. She did her Ph.D. with the Berkeley Automated Supernova Search, which measured the supernova rates as a function of supernova type in Virgo-distance galaxies; and the Supernova Cosmology Project (SCP), which is measured the cosmological parameters Omega and Lambda using the light curves of distant supernovae. She shared the Gruber Cosmology Prize for her work with SCP. She helped to build the Sloan Digital Sky Survey (SDSS), which imaged ~10,000 square degrees of the sky in five optical filters, and obtained over a million spectra of galaxies. She initiated the Sloan Extension for Galactic Understanding and Exploration (SEGUE) project in SDSS II, which obtained spectra for 250,000 Galactic stars. She has published papers in diverse areas of galactic and extragalactic astronomy, including: supernova phenomenology, measuring cosmological parameters from supernovae, galaxy photometry, color selection of QSOs, properties of stars, astronomy education, and the structure of our galaxy.
Research Interests:
Newberg is the head of Participants in LAMOST, US (PLUS), which is proposing to collaborate with the Chinese LAMOST project to obtain 2.5 million spectra of Galactic stars, using a new 4m-class telescope that can obtain spectra for 4000 objects at the same time and is being built at Xinglong Observatory in China.
Newberg’s current research is primarily related to understanding the structure of our own galaxy through using A stars as tracers of the galactic halo, and using photometrically determined metallicities of main sequence F-K stars to determine whether the thick disk is chemically distinct from the thin disk and galactic halo of our galaxy.
