Metal enrichment of the neutral gas of blue compact dwarf galaxies: the compelling case of Pox 36
V. Lebouteiller, D. Kunth, T. X. Thuan +1
We present the analysis of the interstellar spectrum of Pox 36 with the Far Ultraviolet Spectroscopic Explorer (FUSE). Pox 36 was selected because of the relatively low foreground…
The extrasolar planet atmosphere and exosphere: Emission and transmission spectroscopy
Giovanna Tinetti, Jean-Philippe Beaulieu
We have entered the phase of extrasolar planets characterization, probing their atmospheres for molecules, constraining their horizontal and vertical temperature profiles and estim…
Structural properties of disk galaxies: The intrinsic equatorial ellipticity of bulges
J. Méndez-Abreu, J. A. L. Aguerri, E. M. Corsini +1
The structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies were derived to study the correlations between bulge and disk parameters as well as the proba…
Structural properties of disk galaxies I. The intrinsic ellipticity of bulges
J. Mendez-Abreu, J. A. L. Aguerri, E. M. Corsini +1
(Abridged) A variety of formation scenarios was proposed to explain the diversity of properties observed in bulges. Studying their intrinsic shape can help in constraining the domi…
Towards the optimal window for the 2MASS dipole
Michal Chodorowski, Jean-Baptiste Coiffard, Maciej Bilicki +2
A comparison of the 2MASS flux dipole to the CMB dipole can serve as a method to constrain a combination of the cosmological parameter Omega_m and the luminosity bias of the 2MASS…
The HARPS search for southern extra-solar planets XI. Super-Earths (5 & 8 M_Earth) in a 3-planet system
S. Udry, X. Bonfils, X. Delfosse +8
This Letter reports on the detection of two super-Earth planets in the Gl581 system, already known to harbour a hot Neptune. One of the planets has a mass of 5 M_Earth and resides…
CalFUSE v3: A Data-Reduction Pipeline for the Far Ultraviolet Spectroscopic Explorer
W. V. Dixon, D. J. Sahnow, P. E. Barrett +13
Since its launch in 1999, the Far Ultraviolet Spectroscopic Explorer (FUSE) has made over 4600 observations of some 2500 individual targets. The data are reduced by the Principal I…
Continuum gamma-ray emission from light dark matter positrons and electrons
P. Sizun, M. Casse, S. Schanne
The annihilation of light dark matter was recently advocated as a possible explanation of the large positron injection rate at the Galactic center deduced from observations by the…
Microquasars as sources of positron annihilation radiation
N. Guessoum, P. Jean, N. Prantzos
We consider the production of positrons in microquasars, i.e. X-ray binary systems that exhibit jets frequently, but not continuously. We estimate the production rate of positrons…
Refined parameters of the planet orbiting HD 189733
G. A. Bakos, H. Knutson, F. Pont +13
We report on the BVRI multi-band follow-up photometry of the transiting extrasolar planet HD 189733b. We revise the transit parameters and find planetary radius RP = 1.154+/- 0.032…
On the nature of X-Ray Flashes
C. Barraud, F. Daigne, R. Mochkovitch +1
We discuss the origin of X-Ray Flashes (XRFs), a recently discovered class of Gamma-Ray Bursts (GRBs). Using a simplified model for internal shocks we check if XRFs can be intrinsi…
FUSE observations of molecular hydrogen on the line of sight towards HD141569A
C. Martin-Zaidi, M. Deleuil, T. Simon +5
We present an analysis of the Far Ultraviolet Spectroscopic Explorer (FUSE) spectrum of HD141569A, a transitional object known to possess a circumstellar disk. We observe two compo…
Stellar Content from high resolution galactic spectra via Maximum A Posteriori
P. Ocvirk, C. Pichon, A. Lancon +1
This paper describes STECMAP (STEllar Content via Maximum A Posteriori), a flexible, non-parametric inversion method for the interpretation of the integrated light spectra of galax…
Infrared Number Counts of AGN in the GOODS Fields
E. Treister, C. Megan Urry, the GOODS AGN Team
Using the known numbers and evolution of unobscured AGN, and assuming that there is a large number of corresponding obscured AGN -- as expected if AGN unification is correct -- we…
The 2-850 micron SED of starforming galaxies
Anna Sajina, Douglas Scott, Michel Dennefeld +3
We present preliminary results on a study of the 2--850 micron SEDs of a sample of 30 FIRBACK galaxies selected at 170 micron. These sources are representative of the brightest ~10…
The visibility of the Galactic bulge in optical surveys. Application to the Gaia mission
A. C. Robin, C. Reylé, S. Picaud +1
The bulge is a region of the Galaxy which is of tremendous interest for understanding Galaxy formation. However, measuring photometry and kinematics in it raises several inherent i…
The star formation history of Seyfert 2 nuclei
R. Cid Fernandes, Q. Gu, J. Melnick +5
We present a study of the stellar populations in the central ~ 200 pc of a large and homogeneous sample comprising 79 nearby galaxies, most of which are type 2 Seyferts. The star-f…
Obscured AGN and the X-ray, Optical and Far-Infrared Number Counts of AGN in the GOODS Fields
E. Treister, C. M. Urry, E. Chatzichristou +12
The deep X-ray, optical, and far-infrared fields that constitute GOODS are sensitive to obscured AGN (N_H>10^{22} cm^{-2}) at the quasar epoch (z~2-3), as well as to unobscured AGN…
