Polarimetric Signatures from Ice Crystals Observed at 95 Ghz in Winter Clouds. Part Ii: Frequencies of Occurrence

Constraints on Free-free Emission from Anomalous Microwave Emission Sources in the Perseus Molecular Cloud

We present observations performed with the Green Bank Telescope at 1.4 and 5 GHz of three strips coincident with the anomalous microwave emission features previously identified in the Perseus molecular cloud at 33 GHz with the Very Small Array. With these observations we determine the level of the low frequency (∼ 1 – 5 GHz) emission. We do not detect any significant extended emission in these ...

POLARIMETRIC SIGNATURES FROM ICE CRYSTALS OBSERVED AT 95 GHz IN WINTER CLOUDS. PART I: DEPENDENCE ON CRYSTAL FORM

Microwave ISM Emission Observed by WMAP

We investigate the nature of the diffuse Galactic emission in the Wilkinson Microwave Anisotropy Probe (WMAP) temperature anisotropy data. Substantial dust-correlated emission is observed at all WMAP frequencies, far exceeding the expected thermal dust emission in the lowest frequency channels (23, 33, 41 GHz). The WMAP team (Bennett et al. ) interpret this emission as dust-correlated synchrotr...

Dust Structure and Composition Within Molecular Clouds and Cores

Title of Dissertation: Dust Structure and Composition Within Molecular Clouds and Cores Nicholas Lane Chapman, Doctor of Philosophy, 2007 Dissertation directed by: Professor Lee G. Mundy Department of Astronomy We observed three molecular clouds and four isolated cores at wavelengths from 3.6− 24 μm. The clouds we observed were Ophiuchus, Perseus, and Serpens and the cores were L204C-2, L1152, ...
