The AKARI FIS Catalogue of YSOs and Extragalactic Objects

Marton, Gabor; Zahorecz, Sarolta; Toth, L. Viktor +2 more

The point sources in the Bright Source Catalogue of the AKARI Far-Infrared Surveyor (FIS) were classified based on their FIR and mid-IR fluxes and colours into young stellar object (YSO) and extragalactic source types using Quadratic Discriminant Analysis method (QDA) and Support Vector Machines (SVM). The reliability of the selection of YSO candi…

We selected 47 DOGs at z∼1.5 using optical R (or r^{'}), AKARI 18 µm, and 24 µm color in the AKARI North Ecliptic Pole (NEP) Deep survey field. Using the colors among 3, 4, 7, and 9µm, we classified them into 3 groups; bump DOGs (23 sources), power-law DOGs (16 sources), and unknown DOGs (8 sources). We built spectral energy…

Nep-Akari Evolution with Redshift of Dust Attenuation in 8 ㎛ Selected Galaxies

Buat, V.; Burgarella, D.; Serjeant, S. +8 more

We built a 8um selected sample of galaxies in the NEP-AKARI field by defining 4 redshift bins with the four AKARI bands at 11, 15, 18 and 24 microns (0.15<z<0.49, 0.75<z<1.34, 1.34<z<1.7 and 1.7<z<2.05) . Our sample contains 4079 sources, 599 are securely detected with Herschel/PACS. Also adding ultraviolet (UV) data from G…
