| We propose near-infrared (NIR) imaging of a nearby (d=325 pc) molecular cloud G159.23-43.51 targeted already in the Herschel project Galactic Cold Cores and in Spitzer project Star Formation and Structure in two High-Latitude Molecular Clouds. Our study is concerned with the initial stages of star formation. NOTCam J and Ks band data will be used to derive an estimate of NIR extinction that complement our Herschel data and help to determine the structure and stability of the cores. NOTCam measurements of scattered light provide information on the radiation field and NIR dust properties. With Spitzer mid-infrared data of the coreshine phenomenon, these will be used to determine dust properties and especially to measure grain growth. The results on grain coagulation are relevant for the chemistry and thermal balance of cloud cores in general. By dening the initial conditions for later evolution, the results have important implications even for protostellar disks and the ensuing planet formation.\\ | We propose near-infrared (NIR) imaging of a nearby (d=325 pc) molecular cloud G159.23-43.51 targeted already in the Herschel project Galactic Cold Cores and in Spitzer project Star Formation and Structure in two High-Latitude Molecular Clouds.

| + | This is a short observing program to check the feasibility of detecting | ||
| + | dust in BL Lacertae host galaxies. We will concentrate on one BL Lac | ||
| + | which clearly shows a dust lane in the optical plus a few candidates | ||
| + | and one or two control targets. We will use BVIJH imaging plus existing | ||
| + | R-band data to study the colors of the host galaxies and study | ||
| + | the presence of dust from there.\\ | ||
