The Far-Infrared Surveyor (FIS) for AKARI
Mitsunobu Kawada, Hajime Baba, Peter D. Barthel +57
The Far-Infrared Surveyor (FIS) is one of two focal plane instruments on the AKARI satellite. FIS has four photometric bands at 65, 90, 140, and 160 um, and uses two kinds of array…
AKARI infrared imaging of reflection nebulae IC4954 and IC4955
Daisuke Ishihara, Takashi Onaka, Hidehiro Kaneda +26
We present the observations of the reflection nebulae IC4954 and IC4955 region with the Infrared Camera (IRC) and the Far-Infrared Surveyor (FIS) on board the infrared astronomical…
Flight Performance of the AKARI Cryogenic System
Takao Nakagawa, Keigo Enya, Masayuki Hirabayashi +11
We describe the flight performance of the cryogenic system of the infrared astronomical satellite AKARI, which was successfully launched on 2006 February 21 (UT). AKARI carries a 6…
The Infrared Astronomical Mission AKARI
H. Murakami, H. Baba, P. Barthel +90
AKARI, the first Japanese satellite dedicated to infrared astronomy, was launched on 2006 February 21, and started observations in May of the same year. AKARI has a 68.5 cm cooled…
Optical Identification of the ASCA Lynx Deep Survey: An Association of QSOs and a Supercluster at z=1.3?
Kouji Ohta, Masayuki Akiyama, Yoshihiro Ueda +6
Results of optical identification of the ASCA Lynx deep survey are presented. Six X-ray sources are detected in the 2-7 keV band using the SIS in a 20'x20' field of view with fluxe…
Multiwavelength Observations of a Dramatic High Energy Flare in the Blazar 3C 279
A. E. Wehrle, E. Pian, C. M. Urry +3
The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week…
Multiwavelength Monitoring of the BL Lacertae Object PKS 2155-304 in May 1994. II. The IUE Campaign
Elena Pian, C. Megan Urry, Aldo Treves +16
PKS 2155-304, the brightest BL Lac object in the ultraviolet sky, was monitored with the IUE satellite at ~1 hour time-resolution for ten nearly uninterrupted days in May 1994. The…
Multiwavelength Monitoring of the BL Lacertae Object PKS 2155-304 in May 1994. III. Probing the Inner Jet through Multiwavelength Correlations
C. Megan Urry, A. Treves, L. Maraschi +16
In May 1994 the BL Lac object PKS 2155-304 was observed continuously for ~10 d with IUE and EUVE and for 2 d with ASCA, as well as with ROSAT and with ground- based radio, IR, and…
Multi-wavelength Observations of 3C 273 in 1993-1995
C. von Montigny
We present the results of the multi-wavelength campaigns on 3C 273 in 1993-1995. During the observations in late 1993 this quasar showed an increase of its flux for energies greate…
The ASCA X-ray spectrum of the powerful radio galaxy 3C109
S. W. Allen, A. C. Fabian, E. Idesawa +3
We report the results from an ASCA X-ray observation of the powerful Broad Line Radio Galaxy, 3C109. The ASCA spectra confirm our earlier ROSAT detection of intrinsic X-ray absorpt…
ASCA Observations of the Composite Warm Absorber in NGC 3516
G. A. Kriss, J. H. Krolik, C. Otani +11
We obtained X-ray spectra of the Seyfert 1 galaxy NGC~3516 in March 1995 using ASCA. Simultaneous far-UV observations were obtained with HUT on the Astro-2 shuttle mission. The ASC…
The variable OVIII Warm Absorber in MCG-6-30-15
C. Otani, T. Kii, C. S. Reynolds +8
We present the results of a 4 day ASCA observation of the Seyfert galaxy MCG-6-30-15, focussing on the nature of the X-ray absorption by the warm absorber, characterizd by the K-ed…
