Foreground of Gamma-Ray Bursts (grbs) from Akari Fis Data
Doi, Yasuo; Zahorecz, Sarolta; Toth, L. Viktor +4 more
A significant number of the parameters of a gamma-ray burst (GRB) and its host galaxy are calculated from the afterglow. There are various methods obtaining extinction values for the necessary correction for galactic foreground. These are: galaxy counts, from HI 21 cm surveys, from spectroscopic measurements and colors of nearby Galactic stars, or…
Strong Gravitational Lenses and Multi-Wavelength Galaxy Surveys with Akari, Herschel, SPICA and EUCLID
Serjeant, Stephen
Submillimetre and millimetre-wave surveys with Herschel and the South Pole Telescope have revolutionised the discovery of strong gravitational lenses. Their follow-ups have been greatly facilitated by the multi-wavelength supplementary data in the survey fields. The forthcoming Euclid optical/near-infrared space telescope will also detect strong g…

AKARI Spectroscopy of Quasars at 2.5 - 5 µm
Nakagawa, Takao; Ohyama, Youichi; Im, Myungshin +5 more
Utilizing a unique capability of AKARI that allows deep spectroscopy at 2.5 - 5.0 µm, we performed a spectroscopy study of more than 200 quasars through one of the AKARI mission programs, QSONG (Quasar Spectroscopic Observation with NIR Grism). QSONG targeted 155 high redshift (3.3 < z < 6.42) quasars and 90 low redshift active galacti…
The AGN Population in the Akari NEP Deep Field
Pearson, Chris; Serjeant, Stephen; Matsuhara, Hideo +6 more
The AKARI North Ecliptic Pole Deep Field is a natural location to accomplish deep extragalactic surveys. It is supported by comprehensive ancillary data extending from radio to X-ray wavelengths, which have been used to classify radio sources as radio-loud and radio-quiet objects and to create a catalogue of Active Galactic Nuclei (AGN). This has …

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…
