genesis

Japanese Deep Surveys with ISObservations were very successful and provided valuable data on star forming activity and galaxy evolution. Model calculations indicate that there was an intense star formation period that peaked at around . = 0.7.

Deep Far Infrared ISOPHOT Survey in “Selected Area 57”Space Observatory (ISO.) at both 60 μm and 90 μm. We describe our data reduction and analysis scheme with special emphasis on source extraction and flux calibration. With a formal signal to noise ratio of 6.75 we have source detection limits of 90 mJy at 60 μm and 50 mJy at 90 μm. To these limits we

Based on the far-infrared spectral energy distributions it is likely that dust-enshrouded, distant galaxies form a significant fraction of the sources..We estimate the number densities of extragalactic sources at 90μm, 150μm and

After subtracting the contribution of faint stars and zodiacal component based on the model, significant isotropic emission is detected whose in-band flux amounts to ～ 30 nWm.sr.. This brightness is consistent with upper limits of COBE/DIRBE, but is much brighter than the integr

A Local Infrared Perspective to Deeper ISO Surveysd comparison with ISO surveys and review their problems. We provide a stellar infrared diagnostic diagram to distinguish galaxies from stars without using longer wavelength IRAS colour criteria and produce complete 12 μm samples of galaxies and stars. This new technique allows us to estimate the con
