Modeling of Emission Signatures of Massive Black Hole Binaries: I Methods
Tamara Bogdanovic, Britton D. Smith, Steinn Sigurdsson +1
We model the electromagnetic signatures of massive black hole binaries (MBHBs) with an associated gas component. The method comprises numerical simulations of relativistic binaries…
Metal Cooling in Simulations of Cosmic Structure Formation
Britton D. Smith, Steinn Sigurdsson, Tom Abel
The addition of metals to any gas can significantly alter its evolution by increasing the rate of radiative cooling. In star-forming environments, enhanced cooling can potentially…
The Transition from the First Stars to the Second Stars in the Early Universe
Britton D. Smith, Steinn Sigurdsson
We observe a sharp transition from a singular, high-mass mode of star formation, to a low-mass dominated mode, in numerical simulations, at a metallicity of 10^-3 Zsolar. We incorp…
