Multi-Wavelength Properties of the Type IIb SN 2008ax
P. W. A. Roming, T. A. Pritchard, P. J. Brown +11
We present the UV, optical, X-ray, and radio properties of the Type IIb SN 2008ax discovered in NGC 4490. The observations in the UV are one of the earliest of a Type IIb supernova…
Spectra and Light Curves of Failed Supernovae
Chris L. Fryer, Peter J. Brown, Filomena Bufano +11
Astronomers have proposed a number of mechanisms to produce supernova explosions. Although many of these mechanisms are now not considered primary engines behind supernovae, they d…
Ultraviolet Spectroscopy of Supernovae: The First Two Years of Swift Observations
F. Bufano, S. Immler, M. Turatto +13
We present the entire sample of ultraviolet (UV) spectra of supernovae (SNe) obtained with the Ultraviolet/Optical Telescope (UVOT) on board the Swift satellite during the first 2…
X-rays from the explosion site: Fifteen years of light curves of SN 1993J
Poonam Chandra, Vikram V. Dwarkadas, Alak Ray +2
We present a comprehensive analysis of the X-ray light curves of SN 1993J in a nearby galaxy M81. This is the only supernova other than SN 1987A, which is so extensively followed i…
23 GHz VLBI Observations of SN 2008ax
I. Marti-Vidal, J. M. Marcaide, A. Alberdi +14
We report on phase-referenced 23 GHz Very-Long-Baseline-Interferometry (VLBI) observations of the type IIb supernova SN 2008ax, made with the Very Long Baseline Array (VLBA) on 2 A…
The He-rich core-collapse supernova 2007Y: Observations from X-ray to Radio Wavelengths
Maximilian Stritzinger, Paolo Mazzali, Mark M. Phillips +21
A detailed study spanning approximately a year has been conducted on the Type Ib supernova 2007Y. Imaging was obtained from X-ray to radio wavelengths, and a comprehensive set of m…
