tokens: This work is based on observations with the VLA, operated by the NRAO, and the 100-m telescope of the MPIfR (Max-Planck-Institut für Radioastronomie) at Effelsberg. This work is based in part on archival data obtained with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under a contract with NASA. This publication makes use of data products from the Wide-field Infrared Survey Explorer (WISE), which is a joint project of the University of California, Los Angeles, and the Jet Propulsion Laboratory/California Institute of Technology, funded by the National Aeronautics and Space Administration. The author thanks the operators at the Effelsberg telescope for their support, the VLA team for performing the observations and help during data reduction, Bill Sherwood for processing the Effelsberg data at and Uli Klein for help with generating Fig. 27 . Aritra Basu, Michal Hanasz, Marita Krause, Woong-Tae Kim, and Fatemeh Tabatabaei are acknowledged for useful discussions and comments. Special thanks go to Marita Krause and Elly M.
