Supermassive Black Hole Model Predicts Characteristic Light Signals at Cusp of Collision

Magnetic field lines emanate from a pair of supermassive black holes nearing merger within a large gas disk in a simulation by RIT scientists. Periodic light signals in the gas disk could someday help scientists locate supermassive binary black holes. Credit: RIT Center for Computational Relativity and Gravitation

Multimessenger astrophysics. A new simulation of supermassive black holes – the behemoths at the centers of galaxies – uses a realistic scenario to predict the light signals emitted in the surrounding gas before the masses collide, said Rochester Institute of Technology researchers...

Recreating Outer Space in the Lab

Physical picture of the electron gas expanding in the magnetic wall, where Q = 0 for the adiabatic expansion, resulting in a change of the internal energy of the electron gas is equal to the work done on their surroundings. The magnetic field can behave as a flexible wall with no heat transfer, i.e., the perfectly adiabatic wall. Credit: Kazunori Takahashi

Extending thermodynamics to out of equilibrium electron gas in a magnetic nozzle. Thermodynamics provides insight into the internal energy of a system and the energy interaction with its surroundings. This relies on the local thermal equilibrium of a system. A challenging topic of research has been the application of classical thermodynamics to out of equilibrium systems, e.g...

ESO’s VLT working as 16-meter Telescope for first time

The ESPRESSO instrument on ESO's Very Large Telescope in Chile has used the combined light of all four of the 8.2-meter Unit Telescopes for the first time. Combining light from the Unit Telescopes in this way makes the VLT the largest optical telescope in existence in terms of collecting area. This picture shows in highly simplified form how the light collected by all four VLT Unit Telescopes is combined in the ESPRESSO instrument, located under the VLT platform. Credit: ESO/L. Calçada

New research offers an explanation for the discrepancy between the size and age of the Rosetta Nebula’s central cavity and that of its central stars. A hole at the heart of a stunning rose-like interstellar cloud has puzzled astronomers for decades. But new research, led by the University of Leeds, offers an explanation for the discrepancy between the size and age of the Rosetta Nebula’s central cavity and that of its central stars...
