Date: Nov 12 Speaker: Alicia Soderberg Title: A Fresh Approach to Bridging Observations and Theory of Cosmic
Explosions Abstract: Throughout history, observational supernova (SN) studies have focused
almost exclusively on their strong optical emission that dominates the
bolometric luminosity of all SN classes. Yet many of the leading
breakthroughs in our understanding of supernovae and their progenitors
have been enabled by observations at other wavelengths. For example,
through the combination of radio, X-ray and gamma-ray observations, we
now know that less than 1 percent of all Type Ibc supernovae harbor
ultra-relativistic gamma-ray burst jets (GRBs, including those pointed
away from us) that are visible to the far reaches of the Universe and
enable unique galaxy evolution studies. The progenitors of GRBs must
therefore share unusual properties, the nature of which remain hotly
debated, and are likely to be revealed only through a detailed study
of local SNe Ibc. Similarly, as Type Ia SN studies are extended to
higher redshifts and trusted to constrain cosmological parameters, the
favored single-degenerate white dwarf model is increasingly called
into question by sensitive radio and X-ray observations of nearby SNe
Ia that have yet to reveal evidence for a donor star's wind.
Theoretical considerations suggest that progenitor mass, metallicity,
angular momentum and binary interaction all play a role in the
production of GRBs, SNe Ibc and SNe Ia. I will present a fresh
approach to bridge observations and theory of cosmic explosions that
will shed light on the nature of their progenitors.
