Boxy/Peanut bulges and stellar bars
Martinez-Valpuesta, I., Athanassoula +1
Boxy/peanut bulges in disc galaxies have been associated to stellar bars. We analyse their properties in a large sample of -body simulations, using different methods to measure…
Detecting false alarms in transit data from space: Rejection methods tested in Corot Blind Test 2
J. M. Almenara, H. J. Deeg, C. Regulo +1
Transit searches provide a large number of planet candidates. Before attempting follow-up observations, the best effort should be spent in classifying the light-curves, rejecting f…
UV dust attenuation in spiral galaxies: the role of age-dependent extinction and of the IMF
P. Panuzzo, G. L. Granato, V. Buat +4
We analyse the attenuation properties of a sample of UV selected galaxies, with the use of the spectrophotometric model Grasil. In particular, we focus on the relation between dust…
The Evolution of the Visible and Hidden Star Formation in the Universe: Implication from the Luminosity Functions at FUV and FIR
Tsutomu T. Takeuchi, Veronique Buat, Denis Burgarella
Based on GALEX and IRAS/Spitzer datasets, we have found that both FUV and FIR luminosity functions (LFs) show a strong evolution from z=0 to z=1, but the FIR LF evolves much strong…
OH Absorption in the Line of Sight Towards Sagittarius B2
E. T. Polehampton, J. -P. Baluteau, B. M. Swinyard
The giant molecular cloud complex, Sgr B2, was observed with the ISO Long Wavelength Spectrometer over the range 47-197 microns. The ground state rotational transitions of OH lie i…
Faint companions in the close environment of star-forming dwarf galaxies: possible overlooked starburst triggers?
K. G. Noeske, J. Iglesias-Paramo, J. M. Vilchez +2
Using the NASA Extragalactic Database, we have searched the close environment of 98 star-forming dwarf galaxies (SFDGs) from field- and low density environments for companion galax…
