In this article I will briefly review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio light curves of nearby core-collapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby supernovae and their remnants. These later sec...

Overwhelming evidence has accumulated in recent years that supernova explosions are intrinsically 3-dimensional phenomena with significant departures from spherical symmetry. We review the evidence derived from spectropolarimetry that has established several key results: virtually all supernovae are significantly aspherical near maxim light; core-collapse supernovae behave differently than ther...

Recent studies of core-collapse supernovae have revealed the existence of two distinct classes of massive supernovae (SNe): 1) very energetic SNe (Hypernovae), whose kinetic energy (KE) exceeds 10 erg, about 10 times the KE of normal core-collapse SNe, and 2) very faint and low energy SNe (E ∼ < 0.5 × 10 erg; Faint supernovae). These two classes of supernovae are likely to be ”black-hole-formin...

Long duration γ-ray bursts are thought to be a rare subclass of stripped-envelope core-collapse supernovae that launch collimated relativistic outflows (jets). All γ-ray-burst-associated supernovae are spectroscopically of Type Ic with broad lines, but the fraction of broad-lined Type Ic supernovae harboring low-luminosity γ-ray-bursts remains largely unconstrained. Some supernovae should be ac...

The cosmological utility of type Ia Supernovae prompted numerous studies of these events, and they are now well characterized observationally, both as individual objects and as a population. In contrast, all other types of supernovae (i.e. core-collapse events) are not as well observationally characterized. While some individual events have been studied in great detail (e.g. SN 1987A or SN 1998...

The measurement of the cosmological parameters from Type Ia supernovae hinges on our ability to compare nearby and distant supernovae accurately. Here we present an advance on a method for performing generalized K-corrections for Type Ia supernovae which allows us to compare these objects from the UV to near-IR over the redshift range 0 < z < 2. We discuss the errors currently associated with t...

The Hubble Ultra Deep Field Survey has not only provided the deepest optical and near infrared views of universe, but has enabled a search for the most distant supernovae to z ∼ 2.2. We have found four supernovae by searching spans of integrations of the Ultra Deep Field and the Ultra Deep Field Parallels taken with the Hubble Space Telescope paired with the Advanced Camera for Surveys and the ...

Aims. In the dense stellar environment of globular clusters it is expected that compact binaries can be produced dynamically. This in turn would mean that the fraction of type Ia supernovae that will explode in globular clusters will be higher than would be expected from the mass of stars present. Therefore we wish to determine observational constraints on the number of supernovae type Ia explo...
