Physical properties of dense cores in Orion B9
Oskari Miettinen, Jorma Harju, Lauri K. Haikala +1
We aim to determine the physical and chemical properties of dense cores in Orion B9. We observed the NH3(1,1) and (2,2), and the N2H+(3-2) lines towards the submm peak positions. T…
Accuracy of core mass estimates in simulated observations of dust emission
J. Malinen, M. Juvela, D. C. Collins +2
We study the reliability of mass estimates obtained for molecular cloud cores using sub-millimetre and infrared dust emission. We use magnetohydrodynamic simulations and radiative…
Clouds, filaments and protostars: the Herschel Hi-GAL Milky Way
S. Molinari, B. Swinyard, J. Bally +121
We present the first results from the science demonstration phase for the Hi-GAL survey, the Herschel key-project that will map the inner Galactic Plane of the Milky Way in 5 bands…
Scattered H-alpha emission from a large translucent cloud G294-24
K. Lehtinen, M. Juvela, K. Mattila
We study an undocumented large translucent cloud, detected by means of its enhanced radiation on the SHASSA (Southern H-Alpha Sky Survey Atlas) survey. We consider whether its exce…
