83. Determining nucleosynthesis yields in supernovae from spectral modelling

Oral Presentation

Supernovae are the main production factories of the elements in the Universe. Elements are created both during the hydrostatic burning phases of the progenitor star, and in the explosion. For many decades this framework has relied solely on theoretical predictions, but lately spectral synthesis models as well as improved supernova data availability has allowed direct abundance measurements. I...

84. Abundance matching, galaxy sizes, and the Tully-Fisher relation in EAGLE

Oral Presentation

The Tully-Fisher relation (TFR) has been interpreted as reflecting the mass-velocity scaling (M ∝ V^3 ) of dark matter halos, but this interpretation has been called into question by abundance-matching (AM) models. We study the TFR of luminous spirals and its relation to AM using the EAGLE set of ΛCDM cosmological simulations. Matching both relations requires disk sizes to satisfy constraints...

85. Big bang nucleosynthesis, the CMB, and the origin of matter and space-time

Grant Mathews

Oral Presentation

This talk will summarize the application of BBN and the CMB to constrain the first moments of the creation of matter in the universe. One expects that the universe was born out of complicated landscape near the Planck time. In these moments the energy scale of superstrings was obtainable during the early moments of chaotic inflation. This talk explores the possibility that a specific...
