Measurement of the extragalactic background light at 8600Å using dark cloud shadow and the CaII-triplet lines
Lauri K. Haikala, Kalevi Mattila, Petri Väisänen
We present results of a measurement of the near infrared Extragalactic Background Light using the dark-cloud method. Long-slit spectra covering the opaque core of the intermediate-…
Optical and UV surface brightness of translucent dark nebulae: Dust albedo, radiation field and fluorescence emission by H2
K. Mattila, M. Haas, L. K. Haikala +4
Photometry of the nebulae LDN1780, LDN1642 and LBN406 is used to derive scattering properties of dust and to investigate the presence of UV fluorescence emission by molecular hydro…
Spectroscopy of diffuse light in dust clouds. Scattered light and the solar neighbourhood radiation field
K. Lehtinen, K. Mattila
The optical surface brightness of dark nebulae is mainly due to scattering of integrated starlight by classical dust grains. It contains information on the impinging interstellar r…
Determination of the cosmic far-infrared background level with the ISOPHOT instrument
M. Juvela, K. Mattila, D. Lemke +3
The cosmic infrared background (CIRB) consists mainly of the integrated light of distant galaxies. In the far-infrared the current estimates of its surface brightness are based on…
ISO far infrared observations of the high latitude cloud L1642. II. Correlated variations of far-infrared emissivity and temperature of "classical large" dust particles
K. Lehtinen, M. Juvela, K. Mattila +2
Our aim is to compare the infrared properties of big, ``classical'' dust grains with visual extinction in the cloud L1642. In particular, we study the differences of grain emissivi…
Odin observations of H2O in the Galactic Centre
Aa. Sandqvist, P. Bergman, J. Black
The Odin satellite has been used to detect emission and absorption in the 557-GHz H2O line in the Galactic Centre towards the Sgr A* Circumnuclear Disk (CND), and the Sgr A +20 km/…
Far infrared observations of pre-protostellar sources in Lynds 183
K. Lehtinen, K. Mattila, D. Lemke +3
Using ISOPHOT maps at 100 and 200um and raster scans at 100, 120, 150 and 200um we have detected four unresolved far-infrared sources in the high latitude molecular cloud L183. Two…
Far-Infrared Emission from Intracluster Dust in Abell Clusters
M. Stickel, U. Klaas, D. Lemke +1
The ISOPHOT instrument aboard ISO has been used to observe extended FIR emission of six Abell clusters. The raw profiles of the I_(120 um) / I_(180 um) surface brightness ratio inc…
Far-infrared and molecular line observations of Lynds 183 - studies of cold gas and dust
M. Juvela, K. Mattila, K. Lehtinen +3
We have mapped the dark cloud L183 in the far-infrared at 100um and 200um with the ISOPHOT photometer aboard the ISO satellite. The observations make it possible for the first time…
