Extragalactic background Light: a measurement at 400 nm using dark cloud shadow II. Spectroscopic separation of dark cloud's light, and results
K. Mattila, P. Väisänen, K. Lehtinen +2
In a project aimed at measuring the optical Extragalactic Background Light (EBL) we are using the shadow of a dark cloud.We have performed, with the ESO VLT/FORS, spectrophotometry…
Extragalactic Background Light: a measurement at 400 nm using dark cloud shadow I. Low surface brightness spectrophotometry in the area of Lynds 1642
K. Mattila, K. Lehtinen, P. Väisänen +2
We present the method and observations for the measurement of the Extragalactic Background Light (EBL) utilizing the shadowing effect of a dark cloud. We measure the surface bright…
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…
Detection of 6 K gas in Ophiuchus D
J. Harju, M. Juvela, S. Schlemmer +3
Cold cores in interstellar molecular clouds represent the very first phase in star formation. The physical conditions of these objects are studied in order to understand how molecu…
A comparison of density structures of a star forming and a non-star-forming globule. DCld303.8-14.2 and Thumbprint Nebula
J. Kainulainen, K. Lehtinen, P. Vaisanen +2
We present a study of radial density structure of the star forming globule, DCld303.8-14.2 (DC303), and a non-star forming globule, Thumbprint Nebula (TPN), using near-infrared dat…
C18O (3-2) observations of the Cometary Globule CG 12: a cold core and a C18O hot spot
L. K. Haikala, M. Juvela, J. Harju +3
The feasibility of observing the C18O (3-2) spectral line in cold clouds with the APEX telescope has been tested. As the line at 329.330 GHz lies in the wing of a strong atmospheri…
