UCI astronomers analyze second-most distant quasar

Using three observatories on Maunakea in Hawaiʻi, astronomers at the University of Arizona have discovered the second-most distant quasar ever found. As part of an international effort to confirm and study the newly discovered object, a team at UCI and UC Santa Barbara used the Keck II 10-meter telescope to perform a spectroscopic analysis. The […]

Milky Way could be catapulting stars into its outer halo, UCI astronomers say

Findings may change fundamental thinking about star system formation, dynamics

UCI astronomer and colleagues confirm existence of exoplanet orbiting nearby star

Using the Habitable Zone Planet Finder instrument, a team of scientists – including UCI astronomer Paul Robertson – has confirmed that an object previously detected by the Kepler space telescope is an exoplanet, a planet orbiting a star outside our solar system. The team’s findings were published recently in The Astronomical Journal. Called G 9-40b, […]

Astronomers discover once-productive galaxy that fizzled out in early universe

An international team of astronomers, including a researcher from UCI’s Department of Physics & Astronomy, has found an ultramassive galaxy as it existed more than 12 billion years ago. Galaxy XMM-2599 was extremely productive early on – hatching more than 300 billion suns by the time the universe had its 1 billionth birthday (it’s now […]

Exoplanet hunting instrument created in part by UCI astronomer makes first observations

UCI astronomer Paul Robertson recently celebrated “first light” for NEID, a new exoplanet hunting instrument he helped develop. Installed at the 3.5-meter WIYN telescope at Kitt Peak National Observatory in Arizona’s Sonoran Desert, NEID is an extremely precise radial velocity spectrometer. Its initial observations were of 51 Pegasi, a sunlike star that, in 1995, was […]

UCI astronomers help implement new sky surveying tool to shed light on dark energy

The Dark Energy Spectroscopic Instrument aimed its robotic array of 5,000 fiber-optic eyes at the night sky for the first time recently to capture images showing its unique view of galaxy light. Mounted on a telescope at Kitt Peak National Observatory near Tucson, Arizona, DESI was designed to explore the mystery of dark energy, which […]

The UCI Podcast: A conversation with Dean James Bullock, School of Physical Sciences

UCI has posted a new podcast episode featuring an interview with the recently appointed dean of the School of Physical Sciences, James Bullock. Arriving at UCI in 2004, Bullock established a reputation as a leading researcher in astronomy and cosmology. He served as chair of the Department of Physics & Astronomy prior to being named […]

Astronomers from UCI and Texas A&M peer into distant black hole’s ‘sphere of influence’

Astronomers at UCI and Texas A&M University have obtained the most detailed view yet of an inner cold gas disk around a distant supermassive black hole. Studying the giant elliptical galaxy NGC 3258 with the Atacama Large Millimeter/submillimeter Array – a powerful radio telescope array in the high desert of northern Chile – the scientists […]

Astronomers find atypically evolved galaxy with tightly packed dark matter at its core

Using data from NASA’s Chandra X-ray Observatory, UCI astronomers have identified a galaxy with an unexpectedly high amount of dark matter at its core. Descended from a family of galaxies called “red nuggets” that formed relatively soon after the Big Bang but were stalled in their growth about 10 billion years ago, Markarian 1216 has […]

The UCI Podcast: New episode explores the history of video games, hunt for exoplanets

A new episode of The UCI Podcast featuring interviews with two UCI faculty members is now available. The first segment is a conversation on the history of video games through the lens of LGBTQ theory with Bonnie “Bo” Ruberg, assistant professor of informatics. Ruberg’s new book, Video Games Have Always Been Queer, is on shelves […]
