On the Nature of AX J2049.6+2939 and AX J2050.0+2914
Emi Miyata, Kouji Ohta, Kenichi Torii +4
AX J2049.6+2939 is a compact X-ray source in the vicinity of the southern blow-up region of the Cygnus Loop supernova remnant (Miyata et al. 1998a). This source was the brightest X…
ISO continuum observations of quasars at z=1-4 I.Spectral energy distributions of quasars from the UV to far-infrared
S. Oyabu, K. Kawara, Y. Tsuzuki +8
Eight luminous quasars with at z = 1.4 - 3.7 have been observed in the mid- and far-infrared using ISO. All the quasars have been detected in the mid-infrared ba…
Exploring Galaxy Evolution from Infrared Number Counts and Cosmic Infrared Background
Tsutomu T. Takeuchi, Takako T. Ishii, Hiroyuki Hirashita +4
Recently reported infrared (IR) galaxy number counts and cosmic infrared background (CIRB) all suggest that galaxies have experienced a strong evolution sometime in their lifetime.…
Unidentified Infrared Emission Bands in the Diffuse Interstellar Medium
Kin-Wing Chan, T. L. Roellig, T. Onaka +7
Using the Mid-Infrared Spectrometer on board the Infrared Telescope in Space and the low-resolution grating spectrometer (PHT-S) on board the Infrared Space Observatory, we obtaine…
ASCA Observation of the Crab-Like Supernova Remnant 3C58
Ken'ichi Torii, Patrick O. Slane, Kenzo Kinugasa +2
We present here the X-ray observation of a Crab-like supernova remnant (SNR) 3C58 with ASCA. We find that the integrated energy spectrum over the nebula is consistent with previous…
Discovery of a new pulsating X-ray source with a 1549.1-s period, AX J183220-0840
M. Sugizaki, K. Kinugasa, K. Matsuzaki +3
A new pulsating X-ray source, AX J183220-0840, with a 1549.1-s period was discovered at R.A.= 18h32m20s and Dec.=-8d40'30'' (J2000, uncertainty=0.6degree) during an ASCA observatio…
