Context. Although the basic processes of star formation (SF) are known, more research is needed on SF across multiple scales and environments.
The Planck all-sky survey provided a large catalog of Galactic cold clouds and clumps that have been the target of several follow-up surveys.
Aims. We aim to characterize a diverse selection of dense, potentially star-forming cores, clumps, and clouds within the Milky Way in terms of
their dust emission and SF activity.
Methods. We studied 53 fields that have been observed in the JCMT SCUBA-2 continuum survey SCOPE and have been mapped with Herschel.
We estimated dust properties by fitting Herschel observations with modified blackbody functions, studied the relationship between dust temperature
and dust opacity spectral index , and estimated column densities. We extracted clumps from the SCUBA-2 850 m maps with the FellWalker
algorithm and examined their masses and sizes. Clumps are associated with young stellar objects found in several catalogs. We estimated the
gravitational stability of the clumps with virial analysis. The clumps are categorized as unbound starless, prestellar, or protostellar.
Results. We find 529 dense clumps, typically with high column densities from (0.3？4.8) 1022 cm？？2, with a mean of (1.5 0.04) 1022 cm？？2, low
temperatures (T 10？20 K), and estimated submillimeter = 1.7 0.1. We detect a slight increase in opacity spectral index toward millimeter
wavelengths. Masses of the sources range from 0.04 M to 4259 M. Mass, linear size, and temperature are correlated with distance. Furthermore,
the estimated gravitational stability is dependent on distance, and more distant clumps appear more virially bound. Finally, we present a catalog
of properties of the clumps.
Conclusions. Our sources present a large array of SF regions, from high-latitude, nearby diuse clouds to large SF complexes near the Galactic
center. Analysis of these regions will continue with the addition of molecular line data, w
