Texas Astronomers Measure Most Massive, Most Unusual Black Hole Using Hobby-Eberly Telescope

Texas Astronomers Measure Most Massive, Most Unusual Black Hole Using Hobby-Eberly Telescope

Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory to measure the mass of what may be the most massive black hole yet — 17 billion times our sun’s mass — in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent.

Astronomers Test Einstein in a New Regime Using Pair of Burnt-Out Stars

A team of astronomers led by researchers from The University of Texas at Austin has confirmed the emission of gravitational waves from the second-strongest known source in our galaxy by studying the shrinking orbital period of a unique pair of burnt-out stars. Their observations tested Albert Einstein's theory of general relativity in a new regime.

University of Texas at Austin Supercomputing Center to Receive $10 Million in Private Funding

The Texas Advanced Computing Center (TACC) at The University of Texas at Austin today announced it has received a commitment of $10 million from the O'Donnell Foundation to advance data-driven science, also called data-enabled or data-intensive science.

Texas Astronomers “Weigh” Heaviest Known Black Hole in our Cosmic Neighborhood

Texas Astronomers “Weigh” Heaviest Known Black Hole in our Cosmic Neighborhood

Astronomers led by Karl Gebhardt of The University of Texas at Austin have measured the most massive known black hole in our cosmic neighborhood by combining data from a giant telescope in Hawai'i and a smaller telescope in Texas.

Project to Study ‘Dark Energy’ Receives $8 Million from National Science Foundation

A project to discover the nature of dark energy, a mysterious force causing the expansion of the universe to speed up, has received an $8 million grant from the National Science Foundation (NSF).

Astronomers Discover Sun’s Twin at McDonald Observatory

Astronomers Discover Sun’s Twin at McDonald Observatory

Peruvian astronomers Jorge Melendez of The Australian National University and Ivan Ramirez of The University of Texas at Austin have discovered the best “solar twin” to date, using the 2.7-meter Harlan J. Smith Telescope at McDonald Observatory. Their findings suggest that the Sun’s chemical composition is not unique, as some previously thought.
