OHIO physicists are getting even closer to the Big Bang, thanks to a new way to examine light from the past

Dr. Hee-Jong Seo

From Ohio University News Ohio University physicists are using data from 20 years of ground-based observations of the night sky from the Sloan Digital Sky Survey to tackle a fundamental physics question: “What are the initial conditions of the universe?” By initial, they are referring to the universe’s primordial growth […]

OHIO Physicists Help Paint First Complete Picture of Expanding Universe, Lead Pursuit of Dark Energy

The SDSS map is shown as a rainbow of colors, located within the observable Universe (the outer sphere, showing fluctuations in the Cosmic Microwave Background). We are located at the center of this map. The inset for each color-coded section of the map includes an image of a typical galaxy or quasar from that section, and also the signal of the pattern that the eBOSS team measures there. As we look out in distance, we look back in time. So, the location of these signals reveals the expansion rate of the Universe at different times in cosmic history.

Except from Ohio University News The Sloan Digital Sky Survey (SDSS) released today a comprehensive analysis of the largest three-dimensional map of the universe ever created, filling in the most significant gaps in the possible exploration of its history, and Ohio University researchers played key roles. The highlights of the […]

By Andrea Wurm Phally Ngoeum, a graduate student from Cambodia, believes in the power of communication. Connecting with people is one reason that she values Oral Communication in Graduate Studies (ELIP 5300). This 3-credit hour class gives her a platform to voice her opinion. “Communicating helps me reduce the gender […]
