Stripped-envelope core-collapse supernovae (i.e., SNe of Type IIb, Ib,
Ic and broad-lined Ic) are supernovae whose massive
progenitors have been stripped of progressively larger amounts of
their hydrogen and helium envelopes. While the SNe Ic-bl associated
with long Gamma Ray Bursts (GRBs) have been studied in detail, the
full range of properties of normal or broad-lined SNe is not...

The Carnegie Supernova Project obtained detailed optical (uBgVri) and near-IR (YJHKs)
light curves of 35 Type Ib/c and Type IIb supernova. This data set is particularly
well-suited to explore color relations over a broad wavelength range, and may offer
new ways to accurately estimate host galaxy extinction. I will present the
photometric sample and results from an initial analysis of the...

Type IIn supernovae (SN IIn) is highly diverse and badly understood class with a
common feature: they show narrow emission lines indicative of a dense circumstellar
matter (CSM). The narrow emission lines could originate either from the undisturbed
circumstellar gas excited by
X-ray/ultraviolet radiation or from shocked circumstellar clouds. In most SNe IIn the
total luminosity is fully...

A relatively small number of CCSNe have been observed to exhibit late-time (>100
d) infrared emission from dust over the past 30 years. Since the launch of Spitzer
(and now even Herschel), the community has had the capability to probe supernova-
associated dust at mid- and far-infrared wavelengths. Combined with ground-based
optical and NIR observations, these data have provided...

Cosmic dust forms in the circumstellar environments of evolved stars with low and
high masses because the synthesis of dust requires high gas densities and
temperatures. Supernovae are one of these environments and form dust in their ejecta
a few months after their explosion. The harsh physical conditions met in the ejecta
and the absence of hydrogen hamper the production of complex...

Young Galactic supernova remnants are unique laboratories for supernova physics. Due
to their proximity they provide us with the most detailed view of the outcome of a
supernova. However, the exact spectroscopic types of their original explosions have
been undetermined so far - hindering to link the wealth of multi-wavelength knowledge
about their remnants with the diverse population of...

I will present a new modeling approach that simultaneously computes spectra and
light curves and takes into account line blanketing, departures from Local
Thermodynamic Equilibrium, time dependent terms in the radiative-transfer, energy,
and statistical-equilibrium equations, as well as non-thermal processes associated
with radioactive decay. Combined with hydrodynamical inputs of SN...
