Description

The NIKA2 dual-band camera at the IRAM 30-meter telescope was used to
obtain maps of the 1 mm and 2 mm dust emission in four regions of the
nearby filaments of Taurus and Perseus. These regions encompass more
than a dozen of dense cores at different stages of evolution in the
process to form stars. The NIKA2 data are combined with published maps
of the dust temperature and of optical extinctions derived from
Herschel maps allowing to study changes of the dust emissivity index
at mm wavelengths with column densities and environment. The observed
indices are then compared with models of grain coagulation and the
build-up of ice mantles.
