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…

Star formation, structure, and formation mechanism of cometary globules: NIR observations of CG 1 and CG 2

M. M. Mäkelä, L. K. Haikala

Cometary globule (CG) 1 and CG 2 are "classic" CGs in the Gum Nebula. They have compact heads and long dusty tails that point away from the centre of the Gum Nebula. We study the s…

The Dark Halo - Spheroid Conspiracy and the Origin of Elliptical Galaxies

Rhea-Silvia Remus, Andreas Burkert, Klaus Dolag +4

Dynamical modeling and strong lensing data indicate that the total density profiles of early-type galaxies are close to isothermal, i.e., rho_tot ~ r^gamma with gamma approx -2. To…

Observations of 6 - 200 μm emission of the Ophiuchus cloud LDN 1688

M. G. Rawlings, M. Juvela, K. Lehtinen +2

We examine two positions, ON1 and ON2, within the Ophiuchus cloud LDN 1688 using observations made with the ISOPHOT instrument aboard the ISO satellite. The data include mid-IR spe…

Planck Intermediate Results. IX. Detection of the Galactic haze with Planck

Planck Collaboration, P. A. R. Ade, N. Aghanim +181

Using precise full-sky observations from Planck, and applying several methods of component separation, we identify and characterize the emission from the Galactic "haze" at microwa…

13CO and C18O J=2-1 mapping of the environment of the Class 0 protostellar core SMM 3 in Orion B9

Oskari Miettinen

We attempt to achieve a better understanding of the gas distribution and velocity field around the deeply embedded Class 0 protostar SMM 3 in the Orion B9 star-forming region. Usin…
