Abstract:
Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are
hypothesized to accelerate cosmic rays in collisionless shocks and
emit GeV γ-rays and TeV neutrinos on a timescale of several
months. We perform the first systematic search for γ-ray
emission in Fermi Large Area Telescope data in the energy range from
100MeV to 300GeV from the ensemble of 147 SNe Type IIn exploding in a
dense CSM. We search for a γ-ray excess at each SNe location in
a one-year time window. In order to enhance a possible weak signal, we
simultaneously study the closest and optically brightest sources of
our sample in a joint-likelihood analysis in three different time
windows (1 year, 6 months, and 3 months). For the most promising
source of the sample, SN 2010jl (PTF 10aaxf), we repeat the analysis
with an extended time window lasting 4.5 years. We do not find a
significant excess in γ-rays for any individual source nor for
the combined sources and provide model-independent flux upper limits
for both cases. In addition, we derive limits on the γ-ray
luminosity and the ratio of γ-ray-to-optical luminosity ratio as
a function of the index of the proton injection spectrum assuming a
generic γ-ray production model. Furthermore, we present detailed
flux predictions based on multi-wavelength observations and the
corresponding flux upper limit at a 95% confidence level (CL) for the
source SN 2010jl (PTF 10aaxf).
Description:
Appendix A (table sncat.dat) lists all of the 147 SNe of this sample
that we consider in our γ-ray search, i.e., all sources with an
estimated explosion time later than 2008 August 4 and before
2012 May 1 (this is one year before the end of the studied γ-ray
data sample).
In this analysis we use 57 months of Fermi LAT data recorded between
2008 August 4 and 2013 May 1 (Fermi Mission Elapsed Time
239557418-389092331s), restricted to the Pass 7 Reprocessed Source
class.
