Constraining the driving mechanism of galaxy-scale winds with emission line spectra (2023)
Presentation / Conference Contribution
Stern, J., Oñorbe, J., Richings, A. J., Johnson, S. D., & Faucher-Giguère, C.-A. (2023, March). Constraining the driving mechanism of galaxy-scale winds with emission line spectra. Presented at Black Hole Winds at All Scales : IAU symposium 378, Haifa, Israel

Using hydrodynamic simulations and photoionization calculations, we demonstrate that quasar emission line spectra contain information on the driving mechanism of galaxy-scale outflows. Outflows driven by a hot shocked bubble are expected to exhibit L... Read More about Constraining the driving mechanism of galaxy-scale winds with emission line spectra.

Heavy Elements Nucleosynthesis on Accreting White Dwarfs Surface: Seeding the p-Process (2019)
Presentation / Conference Contribution
Battino, U., Travaglio, C., Pignatari, M., & Lederer-Woods, C. Heavy Elements Nucleosynthesis on Accreting White Dwarfs Surface: Seeding the p-Process. Presented at Nuclei in the Cosmos XV, Assergi, Italy

© 2019, Springer Nature Switzerland AG. The production of the proton-rich isotopes beyond iron that we observe today in the solar system is still uncertain. Thermonuclear supernovae (SNe Ia) exploding within the single-degenerate scenario have been p...

Inhomogeneous Chemical Evolution of r-Process Elements in the Galactic Halo (2019)
Presentation / Conference Contribution
Wehmeyer, B., Fröhlich, C., Pignatari, M., & Thielemann, F. K. Inhomogeneous Chemical Evolution of r-Process Elements in the Galactic Halo. Presented at Nuclei in the Cosmos XV, Assergi, Italy

© 2019, Springer Nature Switzerland AG. The origin of the heaviest elements is still a matter of debate. For the rapid neutron capture process (“r-process”), multiple sites have been proposed, e.g., neutron star mergers and (sub-classes) of supernova...

H-He Shell Interactions and Nucleosynthesis in Massive Population III Stars (2019)
Presentation / Conference Contribution
Clarkson, O., Herwig, F., Andrassy, R., Woodward, P., Pignatari, M., & Mao, H. H-He Shell Interactions and Nucleosynthesis in Massive Population III Stars. Presented at Nuclei in the Cosmos XV, Assergi, Italy

© 2019, Springer Nature Switzerland AG. We report on our ongoing investigation into the nucleosynthetic and hydrodynamic nature of mixing at the interface between the H- and He-convection zones in massive Pop III stars. Studying recent a grid of 26 1... Read More about H-He Shell Interactions and Nucleosynthesis in Massive Population III Stars.

The vibrational signatures of polyaromatic hydrocarbons on an ice surface (2019)
Presentation / Conference Contribution
Clark, V. H., & Benoit, D. M. The vibrational signatures of polyaromatic hydrocarbons on an ice surface. Presented at Symposium S350: Laboratory Astrophysics: From Observations to Interpretation, Cambridge, UK

© International Astronomical Union 2020. We use quantum chemical techniques to model the vibrational spectra of small aromatic molecules on a proton-ordered hexagonal crystalline water ice (XIh) model. We achieve a good agreement with experimental da... Read More about The vibrational signatures of polyaromatic hydrocarbons on an ice surface.
