It was an event 130 million years in the making yet marked by the speed of light. On October 16 scientists announced they had, for the first time, detected both gravitational waves and light resulting from the collision of neutron stars. The discovery figures heavily into the work of several UT physicists.
The Department of Physics and Astronomy will host an “Ask a Physicist” Facebook Live question and answer session at 11 a.m. Wednesday, April 12, on the department’s Facebook page. Physicists Andrew Steiner and Jun Han will discuss neutron stars, the second most compact objects in the universe.
The Los Alamos National Laboratory recently featured research conducted by Andrew Steiner, UT-ORNL joint faculty assistant professor in the Department of Physics and Astronomy, in a post about how elements on the periodic table are produced.
The speed of sound might just be faster than originally thought, and Assistant Professor of Physics Andrew Steiner has revisited this boundary in “Sound velocity bound and neutron stars,” published in Physical Review Letters.
