Properties of Newly Formed Dust Grains in The Luminous Type IIn Supernova 2010jl
K. Maeda, T. Nozawa, D. K. Sahu +15
Supernovae (SNe) have been proposed to be the main production sites of dust grains in the Universe. Our knowledge on their importance to dust production is, however, limited by obs…
Optical and near-infrared observations of SN 2011dh - The first 100 days
M. Ergon, J. Sollerman, M. Fraser +26
We present optical and near-infrared (NIR) photometry and spectroscopy of the Type IIb supernova (SN) 2011dh for the first 100 days. We complement our extensive dataset with SWIFT…
Comparing Hydrodynamic Models with Observations of Type II Plateau Supernovae
Melina C. Bersten
In this Thesis I developed a one-dimensional Lagrangian hydrodynamic code with flux-limited radiation diffusion including gamma-ray transfer in gray approximation for any given dis…
Early UV/Optical Emission of The Type Ib SN 2008D
Melina C. Bersten, Masaomi Tanaka, Nozomu Tominaga +2
We propose an alternative explanation for the post-breakout emission of SN 2008D associated with the X-ray transient 080109. Observations of this object show a very small contrast…
Extraordinary Magnification of the Ordinary Type Ia Supernova PS1-10afx
Robert M. Quimby, Marcus C. Werner, Masamune Oguri +8
Recently, Chornock and co-workers announced the Pan-STARRS discovery of a transient source reaching an apparent peak luminosity of ~4x10^44 erg s^-1. We show that the spectra of th…
