Star Mergers: A New Test of Gravity, Dark Energy Theories

Image - Artist’s illustration of two merging neutron stars. The rippling space-time grid represents gravitational waves that travel out from the collision, while the narrow beams show the bursts of gamma rays that are shot out just seconds after the gravitational waves. Swirling clouds of material ejected from the merging stars are also depicted. The clouds glow with visible and other wavelengths of light. (Credit: NSF/LIGO/Sonoma State University/A. Simonnet)

Creating a World of Make-Believe to Better Understand the Real Universe

Image - This plot shows a thin slice through a mock galaxies catalog. The blue and green points are “bright” and “faint” galaxies simulated for the Dark Energy Spectroscopic Instrument’s Bright Galaxy Survey, and the red points show galaxies that are brighter than the magnitude limit of the Sloan Digital Sky Survey.

New Simulations Could Help in Hunt for Massive Mergers of Neutron Stars, Black Holes

Image - This image shows the aftermath of a merger between a black hole and neutron star, 5.5 thousandths of a second after the event. This image shows the formation of a wide, hot disk and an inner disk of matter. (Credit: Classical and Quantum Gravity, DOI: 10.1088/1361-6382/aa573b)
