The mm-to-cm SED of spiral galaxies. Synergies between NIKA2 and SRT instruments

TL;DR

This paper discusses the importance of exploring the mm-to-cm spectral energy distribution of spiral galaxies using combined observations from NIKA2 and SRT to better understand dust, free-free, and synchrotron emissions.

Contribution

It proposes a synergy between NIKA2 and SRT instruments and reports on a pilot program to investigate Anomalous Microwave Emission in spiral galaxies.

Findings

Highlighting the need for mm-to-cm coverage to disentangle emission components.

Presenting a pilot K-band program for Anomalous Microwave Emission detection.

Emphasizing the potential for improved dust and ISM modeling.

Abstract

The mm-to-cm range of the Spectral Energy Distribution of spiral galaxies remains largely unexplored. Its coverage is required to disentangle the contribution of dust emission, free-free and synchrotron radiation and can provide constraints on dust models, star-formation rates and ISM properties. We present the case for a synergy between NIKA2 observations of nearby spirals and those from planned and current instrumentation at the Sardinia Radio Telescope, and report on a pilot K-band program to search for Anomalous Microwave Emission, an elusive emission component which is presumably related to dust.
