Far infrared mapping of the galaxies M 51 and M 101 with ISOPHOT ?
We present far infrared (FIR) images of the two nearby galaxies M 51 and M 101 at 60, 100, and at 175mum. These images resolve the spiral arms of the galaxies and a number of giant H ii regions embedded therein.
متن کاملAsteroids as far-infrared photometric standards for ISOPHOT
Asteroids are used as far-IR calibrators for the imaging photopolarimeter ISOPHOT on board the Infrared Space Observatory ISO. For the 10 selected objects we compiled a large uniform database1 of 678 individual observations, ranging from 7–2 000μm. Applying a new thermophysical model to the observations we derived thermal properties of the selected asteroids, based on spin-vector solutions, dir...
متن کاملDeep far infrared ISOPHOT survey in “Selected Area 57” I. Observations and source counts
We present here the results of a deep survey in a 0.4 deg2 blank field in Selected Area 57 conducted with the ISOPHOT instrument aboard ESAs Infrared Space Observatory (ISO1) at both 60 μm and 90 μm. The resulting sky maps have a spatial resolution of 15 × 23 arcsrc2 per pixel which is much higher than the 90 × 90 arcsec2 pixels of the IRAS All Sky Survey. We describe the main instrumental effe...
متن کاملFar-infrared Emission from Dust in the Isophot Virgo Cluster Deep Sample
We review the characteristics of the dust continuum emission from normal galaxies, as revealed by the ISOPHOT Virgo Cluster Deep Survey (Tuffs et al. 2002; Popescu et al. 2002, Popescu & Tuffs 2002b).
متن کاملFar infrared extragalactic background radiation: I. Source counts with ISOPHOT
As a part of the ISOPHOT CIRB (Cosmic Infrared Background Radiation) project we have searched for point-like sources in eight fields mapped at two or three wavelengths between 90μm and 180μm. Most of the 55 sources detected are suspected to be extragalactic and cannot be associated with previously known objects. It is probable, also from the far-infrared (FIR) spectral energy distributions, tha...
