Constraints on the non-thermal emission from η Carinae's blast wave of 1843
Hinton, J. A.; Domainko, W.; Ohm, S. +3 more
Non-thermal hard X-ray and high-energy (HE; 1 MeV < E < 100 GeV) γ-ray emission in the direction of η Carinae has been recently detected using the INTEGRAL, AGILE and Fermi satellites. This emission has been interpreted either in the framework of particle acceleration in the colliding wind region between the two massive stars or in the very …
Multiple outflows from the luminous YSO IRAS 07422-2001
Varricatt, W. P.
The luminous young stellar object (YSO) IRAS 07422-2001 is studied in the infrared (IR). We discover star forming activity in embedded clusters located in a cloud detected at mid-IR wavelengths in emission. Multiple outflows are discovered from these clusters in the H2 ro-vibrational line at 2.122 µm. We detect at least six outflo…
Radiation processes in the Seyfert galaxy NGC 4151
Eriksson, M.
Aims: The main aim of this work was to investigate if the radiative process photoexcitation by accidental resonance (PAR) is producing Fe II lines in the UV region of NGC 4151. At the same time I searched for collisionally excited Fe II emission. While doing so, the broad line region (BLR), intermediate line region (ILR) and narrow line regio…

A multiwavelength study of the IRAS Deep Survey galaxy sample. III. Spectral classification and dynamical properties
Mazzei, P.; Bettoni, D.; Della Valle, A.
Context. The infrared deep sample (IDS), in the north ecliptical polar region (NEPR), is the first complete, far-IR selected sample, on which numerous studies of galaxy evolution are based. Such a sample allows direct investigation of the evolution of dusty galaxies up to a redshift of about 0.3, where the global star formation rate is known to ev…
The role of filament activation in a solar eruption
Fletcher, L.; Romano, P.; Labrosse, N. +2 more
Context. Observations show that the mutual relationship between filament eruptions and solar flares cannot be described in terms of an unique scenario. In some cases, the eruption of a filament appears to trigger a flare, while in others the observations are more consistent with magnetic reconnection that produces both the flare observational sign…
