Astronomy and Astrophysics Sky Confusion Noise in the Far-infrared: Cirrus, Galaxies and the Cosmic Far–infrared Background
We examined the sky confusion noise in 40 sky regions by analysing 175 far-infrared (90–200 µm) maps obtained with ISOPHOT, the photometer on-board the Infrared Space Observatory. For cirrus fields with B > 5 MJysr −1 the formula based on IRAS data (Helou & Be-ichman, (1990)) predicts confusion noise values within a factor of 2 to our measurements. The dependence of the sky confusion noise on t...
متن کاملDetermination of confusion noise for far - infrared measurements ⋆
We present a detailed assessment of the far-infrared confusion noise imposed on measurements with the ISOPHOT far-infrared detectors and cameras aboard the ISO satellite. We provide confusion noise values for all measurement configurations and observing modes of ISOPHOT in the 90 µm ≤ λ ≤ 200 µm wavelength range. Based on these results we also give estimates for cirrus confusion noise levels at...
متن کاملCorrelations in the Far Infrared Background
We compute the expected angular power spectrum of the cosmic Far Infrared Background (FIRB). We find that the signal due to source correlations dominates the shot–noise for l <∼ 1000 and results in anisotropies with rms amplitudes ( √ l(l+ 1)Cl/2π) between 5% and 10% of the mean for l >∼ 150. The angular power spectrum depends on several unknown quantities, such as the UV flux density evolution...
متن کاملRadio Loud Far-infrared Galaxies
We present the first results of a multiwavelength study of IRAS galaxies with excess radio emission. The sample was selected by cross-correlating the IRAS Faint Source Survey (for lbl 2 50') and the Point Source Catalogue (for 10' < lbl < 50') with the Texas radio survey. Recent optical (imaging and spectroscopic) and radio (VLA) observations are discussed. These observations will be used to in...
متن کاملDusty Infrared Galaxies: Sources of the Cosmic Infrared Background
The discovery of the Cosmic Infrared Background (CIB) in 1996, together with recent cosmological surveys from the mid-infrared to the millimeter have revolutionized our view of star formation at high redshifts. It has become clear, in the last decade, that a population of galaxies that radiate most of their power in the far-infrared (the so-called “infrared galaxies”) contributes an important p...
