The AKARI Far-Infrared Surveyor young stellar object catalog
Tamura, Motohide; Kawamura, Akiko; Marton, Gábor +6 more
We demonstrate the use of the AKARI all-sky survey photometric data in the study of galactic star formation. Our aim was to select young stellar objects (YSOs) in the AKARI Far-Infrared Surveyor (FIS) Bright Source Catalogue. We used AKARI/FIS and Wide-field Infrared Survey Explorer (WISE) data to derive mid- and far-infrared colors of YSOs. Class…
Universal profiles of the intracluster medium from Suzaku X-ray and Subaru weak-lensing observations*
Sato, Kosuke; Fukazawa, Yasushi; Nakazawa, Kazuhiro +16 more
We conduct a joint X-ray and weak-lensing study of four relaxed galaxy clusters (Hydra A, A 478, A 1689, and A 1835) observed by both Suzaku and Subaru out to virial radii, with the aim of understanding recently discovered unexpected features of the intracluster medium (ICM) in cluster outskirts. We show that the average hydrostatic-to-lensing tot…
