Timeline analysis and wavelet multiscale analysis of the AKARI All-Sky Survey at 90µm

Goto, Tomotsugu; Nakagawa, Takao; Shirahata, Mai +17 more

We present a careful analysis of the point-source detection limit of the AKARI All-Sky Survey in the WIDE-S 90-µm band near the North Ecliptic Pole (NEP). Timeline analysis is used to detect IRAS (Infrared Astronomy Satellite) sources and then a conversion factor is derived to transform the peak timeline signal to the interpolated 90-µ…

Periodicity search for possible X-ray counterparts to radio-quiet gamma-ray pulsar candidates

Chang, Hsiang-Kuang; Lin, Lupin Chun-Che

A periodicity search of gamma-ray data is usually difficult because of the small number of detected photons. A periodicity in the timing signal at other energy bands from the counterpart to the gamma-ray source may help to establish the periodicity in the gamma-ray emission and strengthen the identification of the source in different energy bands.…

ISINA: INTEGRAL Source Identification Network Algorithm

Hill, A. B.; Bird, A. J.; Scaringi, S. +4 more

We give an overview of ISINA: INTEGRAL Source Identification Network Algorithm. This machine learning algorithm, using random forests, is applied to the IBIS/ISGRI data set in order to ease the production of unbiased future soft gamma-ray source catalogues. First, we introduce the data set and the problems encountered when dealing with images obta…
