TL;DR
The SAFIR project uses Herschel imaging to study the IR emission and star formation in nearby Seyfert galaxies, aiming to understand the dusty torus and coexistence of AGN activity with star formation.
Contribution
This study provides new insights into the physical nature of nuclear IR emission and star formation in AGN hosts through multi-component SED fitting of Herschel data.
Findings
Characterized the IR emission components in Seyfert galaxies.
Analyzed the star formation properties via cold dust emission.
Gained insights into the dusty torus structure in AGN.
Abstract
We present the Seyfert and star formation Activity in the Far-InfraRed (SAFIR) project, a small (15.1h) Herschel guaranteed time proposal performing PACS and SPIRE imaging of a small sample of nearby Seyfert galaxies. This project is aimed at studying the physical nature of the nuclear IR emission by means of multi-component spectral energy distribution (SED) fitting and the star formation properties of AGN hosts, as traced by cold dust. We summarize the results achieved so far and outline the on-going work.
