The warm interstellar medium around the Cygnus Loop
J. Bohigas, J. L. Sauvageot, A. Decourchelle
Observations of the oxygen lines [OII]3729 and [OIII]5007 in the medium immediately beyond the Cygnus Loop supernova remnant were carried out with the scanning Fabry-Pérot spectrop…
Lithium-6 : Evolution from Big Bang to Present
Elisabeth Vangioni-Flam, Michel Casse, Roger Cayrel +3
The primordial abundances of Deuterium, he4, and li7 are crucial to determination of the baryon density of the Universe in the framework of standard Big Bang nucleosynthesis (BBN).…
Deep ISOCAM Observations of Galaxy Clusters
Dario Fadda, David Elbaz
Ten galaxy clusters, with redshift ranging from 0.2 to 1, have been observed with the ISO camera in the two bands LW2 and LW3 (centered respectively at 6.75 and 15 microns). We pre…
Dust in an extremely metal-poor galaxy: mid-infrared observations of SBS 0335-052
T. X. Thuan, M. Sauvage, S. Madden
The metal deficient (Z = Z_sun/41) Blue Compact Dwarf Galaxy (BCD) SBS 0335-052 was observed with ISOCAM between 5 and 17 mic. With a L_12mic/L_B ratio of 2.15, the galaxy is unexp…
Cluster identification via Voronoi tessellation
M. Ramella, M. Nonino, W. Boschin +1
We propose an automated method for detecting galaxy clusters in imaging surveys based on the Voronoi tessellation technique. It appears very promising, expecially for its capabilit…
Bounds on hep neutrinos
G. Fiorentini, V. Berezinsky, S. Degl'Innocenti +1
The excess of highest energy solar-neutrino events recently observed by Superkamiokande can be in principle explained by anomalously high -neutrino flux . Without us…
A classical approach to faint extragalactic source extraction from ISOCAM deep surveys. Application to the Hubble Deep Field
F. -X. Desert, J. -L. Puget, D. L. Clements +4
We have developed a general data reduction technique for ISOCAM data coming from various deep surveys of faint galaxies. In order to reach the fundamental limits of the camera (due…
Are solar granules the only source of acoustic oscillations ?
Thierry Foglizzo
The excitation mechanism of low degree acoustic modes is investigated through the analysis of the stochastic time variations of their energy. The correlation between the energies o…
SIGMA and XTE observations of the soft X-ray transient XTEJ1755-324
P. Goldoni, M. Vargas, A. Goldwurm +13
We present observations of the X-ray transient XTEJ1755-324 performed during summer 1997 with the XTE satellite and with the SIGMA hard X-ray telescope onboard the GRANAT observato…
The converging inflow spectrum is an intrinsic signature for a black hole: Monte-Carlo simulations of Comptonization on free-falling electrons
P. Laurent, L. Titarchuk
An accreting black hole is, by definition, characterized by the drain. Namely, the matter falls into a black hole much the same way as water disappears down a drain - matter goes i…
Standard Solar Models in the Light of New Helioseismic Constraints: I The Solar Core
A. S. Brun, S. Turck-Chieze, P. Morel
In this paper, we examine a new updated solar model taking advantage of recent reexamination of the nuclear reactions rates and of the microscopic diffusion of helium and heavy ele…
The Lx-T Relation and Intracluster Gas Fractions of X-ray Clusters
Monique Arnaud, August E. Evrard
We re-examine the X-ray luminosity-temperature relation using a nearly homogeneous data set of 24 clusters selected for statistically accurate temperature measurements and absence…
Massive Compact Halo Objects Viewed from a Cosmological Perspective: Contribution to the Baryonic Mass Density of the Universe
Brian D. Fields, Katherine Freese, David S. Graff
[Abridged] We estimate the contribution of Massive Compact Halo Objects (Machos) and their stellar progenitors to the mass density of the Universe. If the Machos that have been det…
Deep ISOCAM view of the core of the lensing cluster A2390
L. Lemonon, M. Pierre, C. J. Cesarsky +4
We have imaged the inner square arcminute of the well known lensing and cooling flow cluster A2390 (z = 0.23) down to a sensitivity of 65 and 130 microJy at 6.75 and 15 micronmetre…
Mid--IR emission of galaxies in the Virgo cluster: II. Integrated properties
A. Boselli, J. Lequeux, M. Sauvage +7
We analyse the integrated properties of the Mid-IR emission of a complete, optically selected sample of galaxies in the Virgo cluster observed with the ISOCAM instrument on board t…
The X-ray emission of the polar BL Hydri
G. Matt, R. Barcaroli, T. Belloni +8
We report on the analysis of the ASCA and BeppoSAX X-ray observations of the polar system BL Hyi. Emission from both poles is apparent in both observations; the emission from the s…
The identification of the transient X-ray pulsar Cepheus X-4 with a Be/X-ray binary
Jean-Marc Bonnet-Bidaud, Martine Mouchet
We present long slit spectral (375-725 nm) observations of the proposed identification of the transient 66s X-ray pulsar Cep X-4=GS2138+56. Spectra show features typical of Be/X-ra…
Towards a consistent model of the Galaxy: I. kinematic properties, star counts and microlensing observations
D. Méra, G. Chabrier, R. Schaeffer
We examine the most recent observational constraints arising from i) small-scale and large-scale Galactic dynamical properties, ii) star counts at faint magnitude and iii) microlen…
