A characterization of the diffuse Galactic emissions at large angular scales using the Tenerife data

TL;DR

This paper re-analyzes Tenerife microwave data at large angular scales to investigate Galactic diffuse emissions, providing evidence for dust-correlated emission likely due to spinning dust grains, which aids understanding of the anomalous microwave emission component.

Contribution

It offers a new analysis of Tenerife data at 10-33 GHz, highlighting dust-correlated emission consistent with spinning dust, improving models of Galactic microwave foregrounds.

Findings

Evidence of dust-correlated emission in Tenerife data

Support for spinning dust grain emission as a source

Enhanced understanding of Galactic diffuse emission components

Abstract

The Anomalous microwave emission (AME) has been proved to be an important component of the Galactic diffuse emission in the range from 20 to 60 GHz. To discriminate between different models of AME low frequency microwave data from 10 to 20 GHz are needed. We present here a re-analysis of published and un-published Tenerife data from 10 to 33 GHz at large angular scales (from 5 to 15 degrees). We cross-correlate the Tenerife data to templates of the main Galactic diffuse emissions: synchrotron, free-free and thermal dust. We find evidence of dust correlated emission in the Tenerife data that could be explained as spinning dust grain emission.
