However, many of our current procedures for computing these constraints will not scale well with the increased size of future transient catalogs. We introduce a novel hybrid sampling method in order to more efficiently perform parameterized tests of general relativity with gravitational-wave signals. Applying our method to the binary black hole merger GW150914 and simulated signals we find that our method is approximately an order of magnitude more efficient than the current method with conservative settings for our hybrid analysis. While we have focused on the specific problem of measuring potential deviations from relativity, our method is of much wider applicability to any problem that can be decomposed into a simple and more complex model(s).}, number={10}, journal={PHYSICAL REVIEW D}, author={Wolfe, Noah E. and Talbot, Colm and Golomb, Jacob}, year={2023}, month={May} }

This physics is often encapsulated in the so-called high-temperature nuclear equation of state, which influences compact binary mergers, core-collapse supernovae, and many more phenomena. One such case is the type (either black hole or neutron star) and mass of the remnant of the core collapse of a massive star. For each of six candidate equations of state, we use a very large suite of spherically symmetric supernova models to generate a suite of synthetic populations of such remnants. We then compare these synthetic populations to the observed remnant population. We thus provide a novel constraint on the high-temperature nuclear equation of state and describe which EOS candidates are more or less favored by this metric.}, number={1}, journal={ASTROPHYSICAL JOURNAL LETTERS}, author={Meskhi, Mikhail M. and Wolfe, Noah E. and Dai, Zhenyu and Frohlich, Carla and Miller, Jonah M. and Wong, Raymond K.

Equation of State Dependency of Explosion Properties, Nucleosynthesis Yields, and Compact Remnants}, volume={929}, ISSN={["1538-4357"]}, url={https://doi.org/10.3847/1538-4357/ac4d20}, DOI={10.3847/1538-4357/ac4d20}, abstractNote={In this fifth paper of the series, we use the parametrized, spherically symmetric explosion method PUSH to investigate the impact of eight different nuclear equations of state (EOS). We present and discuss the explosion properties and the detailed nucleosynthesis yields, and predict the remnant (neutron star or black hole) for all our simulations. For this, we perform two sets of simulations. One, a complete study of non-rotating stars from 11 to 40 M$_{\odot}$ at three different metallicities using the SFHo EOS. And two, a suite of simulations for four progenitors (16 M$_{\odot}$ at three metallicities and 25 M$_{\odot}$ at solar metallicity) for eight different nuclear EOS. We compare our predicted explosion energies and yields to observed supernovae and to the metal-poor star HD~84937. We find EOS-dependent differences in the explosion properties and the nucleosynthesis yields. However, when comparing to observations, these differences are not large enough to rule out any EOS considered in this work.}, number={1}, journal={ASTROPHYSICAL JOURNAL}, publisher={American Astronomical Society}, author={Ghosh, Somdutta and Wolfe, Noah and Frohlich, Carla}, year={2022}, month={Apr} }

We analyze broad trends in these light curves and categorize them based on morphology. We find that these morphological categories relate simply to the progenitor radius and mass of the hydrogen envelope. We present a proof-of-concept sensitive-variable analysis, indicating that an important determining factor in the properties of a light curve within a given category is 56Ni mass. We follow spectra from the photospheric to the nebular phase. These spectra show characteristic iron-line blanketing at short wavelengths and Doppler-shifted Fe ii and Ti ii absorption lines. To enable this analysis, we develop a first-of-its-kind pipeline from a massive progenitor model, through a self-consistent explosion in spherical symmetry, to electromagnetic counterparts. This opens the door to more detailed analyses of the collective properties of these observables. We provide a machine-readable database of our light curves and spectra online at go.ncsu.edu/astrodata.}, number={2}, journal={ASTROPHYSICAL JOURNAL}, publisher={American Astronomical Society}, author={Curtis, Sanjana and Wolfe, Noah and Frohlich, Carla and Miller, Jonah M. and Wollaeger, Ryan and Ebinger, Kevin}, year={2021}, month={Nov} }
