  The impact of r-process heating on the dynamics of neutron star merger accretion disc winds and their electromagnetic radiation

  Neutron star merger accretion discs can launch neutron-rich winds of >10−2M⊙. This ejecta is a prime site for r-process nucleosynthesis, which will produce a range of radioactive heavy nuclei. The […]

  Spitzer mid-infrared detections of neutron star merger GW170817 suggests synthesis of the heaviest elements Free

  We report our Spitzer Space Telescope observations and detections of the binary neutron star merger GW170817. At 4.5 μm, GW170817 is detected at 21.9  mag AB at +43 days and 23.9 mag AB at […]

  3D Hydrodynamics of Pre-supernova Outbursts in Convective Red Supergiant Envelopes

  Eruptive mass loss likely produces the energetic outbursts observed from some massive stars before they become core-collapse supernovae (SNe). The resulting dense circumstellar medium may also cause the subsequent SNe […]

  The Landscape of Thermal Transients from Supernovae Interacting with a Circumstellar Medium

  The interaction of supernova ejecta with a surrounding circumstellar medium (CSM) generates a strong shock, which can convert ejecta kinetic energy into observable radiation. Given the diversity of potential CSM […]

  Impact of Systematic Modeling Uncertainties on Kilonova Property Estimation

  The precise atomic structure and therefore the wavelength-dependent opacities of lanthanides are highly uncertain. This uncertainty introduces systematic errors in modeling transients like kilonovae and estimating key properties such as […]
