TL;DR
The AKARI satellite's all-sky survey at far-infrared wavelengths offers detailed maps of the Galactic ISM, revealing dust properties, large-scale structures, and potential star-forming regions with high spatial resolution and accuracy.
Contribution
This paper presents the first all-sky far-infrared maps from AKARI, covering 50-180 um with high resolution and photometric accuracy, enabling new insights into interstellar dust and Galactic structure.
Findings
Mapped large-scale distribution of Galactic dust emission
Estimated dust temperatures using multi-band data
Identified filamentary structures and star-forming regions
Abstract
Far-infrared observations provide crucial data for the investigation and characterisation of the properties of dusty material in the Interstellar Medium (ISM), since most of its energy is emitted between ~100 and 200 um. We present the first all-sky image from a sensitive all-sky survey using the Japanese AKARI satellite, in the wavelength range 50 -- 180 um. Covering >99% of the sky in four photometric bands with four filters centred at 65 um, 90 um, 140 um, and 160 um wavelengths, this achieved spatial resolutions from 1 to 2 arcmin and a detection limit of <10 MJy sr-1, with absolute and relative photometric accuracies of <20%. All-sky images of the Galactic dust continuum emission enable astronomers to map the large-scale distribution of the diffuse ISM cirrus, to study its thermal dust temperature, emissivity and column density, and to measure the interaction of the Galactic…
