8. SNe and SNRs cosmic ray acceleration
2nd Abstract

G29.37+0.10 is a radio system comprising a point-like source and
extended non-thermal emission, which has been proposed to be a new
supernova remnant. The TeV source HESS~J1843$-$033, whose origin is
still uncertain, appears located in projection in coincidence with
G29.37+0.10. We present a radio image of G29.37+0.10 with unprecedented
resolution for this source, based on new observations at 610~MHz carried
out with the Giant Metrewave Radio Telescope. A study combining these
radio data with a spectral and morphological analysis of the X-ray
emission and the interstellar medium was carried out to investigate
whether G29.37+0.10 is a remnant of a stellar explosion and its possible
connection with HESS~J1843$-$033.

8. SNe and SNRs cosmic ray acceleration
1st Abstract

In the last years, with the increasing number of discovered $gamma$-ray
sources, important efforts have been dedicated to establish the origin of
this high-energy emission using observations in other spectral bands. Supernova remnants (SNRs) have been proposed as possible generators of
$gamma$-rays in our Galaxy, among other astrophysical sources. SNR’s shocks are expected to be sites of cosmic ray acceleration
and clouds of dense material can provide an effective target for proton-proton collisions and subsequent production of $gamma$-rays.
We present a preliminary study of the molecular and
atomic material towards G40.5$-$0.5 and G45.7$-$0.4 (two SNRs located in
the vicinity of high-energy sources) and the TeV SNR candidate G44.5$-$0.2, to establish the origin of the $gamma$-ray emission.
In addition, the study of the interstellar medium also provides important clues on how SNRs interact with and modify their local environment.
