    Posterior probability distributions for two methods of measuring the Hubble constant given simulated neutron star merger data.

    Neutron star mergers will resolve tension in Universe's expansion rate measurement

    There are numerous ways to measure the expansion rate of our Universe, otherwise known as the Hubble constant, and right now even the most trusted methods don't agree. This is causing some scientists to argue that there are problems with the standard cosmological model. In the next ten years, neutron star mergers will be able to solve the problem.

    Simulations predict the linear polarization expected from merging neutron stars

    An international team led by OKC researcher Dr. Mattia Bulla uses simulations and observations to show that the first-ever observed system of merging neutron stars was inclined to within 60 degrees of the polar direction. These simulations indicate that light from merging neutron star systems will be most polarized for the first couple of days after the event.

    OKC researchers secure HST time in Cycle 26

    Angela Adamo and Matthew Hayes both had successful medium HST proposals in Cycle 26, the most oversubscribed cycle in the history of HST. Angela's observations will explore how dense, young clusters of stars interact with their surroundings. Matthew's observations will look for gas that is thought to envelope galaxies and fuel their future generations of stars.
