Descripción
We present results from observations made at 33 GHz with the Very Small
Array (VSA) telescope towards potential candidates in the Galactic plane
for spinning dust emission. In the cases of the diffuse HII regions
LPH96 and NRAO591 we find no evidence for anomalous emission and, in
combination with Effelsberg data at 1.4 and 2.7GHz, confirm that their
spectra are consistent with optically thin free-free emission. In the
case of the infrared bright supernova remnant 3C396 we find emission
inconsistent with a purely non-thermal spectrum and discuss the
possibility of this excess arising from either a spinning dust component
or a shallow spectrum pulsar wind nebula, although we conclude that the
second case is unlikely given the strong constraints available from
lower-frequency radio images.
