TL;DR
The paper introduces a comprehensive far-infrared all-sky map from the AKARI satellite, covering over 99% of the sky in four bands, enabling detailed study of interstellar dust and cirrus structures.
Contribution
It presents the first public release of high-resolution, multi-band all-sky far-infrared maps from AKARI, improving spatial resolution over previous surveys.
Findings
Maps cover >99% of the sky in four bands
Enhanced spatial resolution reveals detailed ISM structures
Data set serves as a legacy resource for astronomy
Abstract
We present a far-infrared all-sky atlas from a sensitive all-sky survey using the Japanese satellite. The survey covers % of the sky in four photometric bands centred at 65 m, 90 m, 140 m, and 160 m with spatial resolutions ranging from 1 to 1.5 arcmin. These data provide crucial information for the investigation and characterisation of the properties of dusty material in the Interstellar Medium (ISM), since significant portion of its energy is emitted between 50 and 200 m. The large-scale distribution of interstellar clouds, their thermal dust temperatures and column densities, can be investigated with the improved spatial resolution compared to earlier all-sky survey observations. In addition to the point source distribution, the large-scale distribution of ISM cirrus emission, and its filamentary structure, are well traced. We have made…
