Limits on the Macho Content of the Galactic Halo from the EROS-2 Survey of the Magellanic Clouds
P. Tisserand, L. Le Guillou, C. Afonso +35
The EROS-2 project was designed to test the hypothesis that massive compact halo objects (the so-called ``machos'') could be a major component of the dark matter halo of the Milky…
Type Ia supernova rate at a redshift of ~ 0.1
G. Blanc, C. Afonso, C. Alard +58
We present the type Ia rate measurement based on two EROS supernova search campaigns (in 1999 and 2000). Sixteen supernovae identified as type Ia were discovered. The measurement o…
Bulge Microlensing Optical Depth from EROS 2 observations
C. Afonso, J. -N. Albert, C. Alard +7
We present a measurement of the microlensing optical depth toward the Galactic bulge based on the analysis of 15 contiguous1 square degrees fields centered on (l=2.5 deg, b=-4.0 de…
Limits on Galactic Dark Matter with 5 Years of EROS SMC Data
EROS Collaboration
Five years of EROS data towards the Small Magellanic Cloud have been searched for gravitational microlensing events, using a new, more accurate method to assess the impact of stell…
Observation of periodic variable stars towards the galactic spiral arms by EROS II
F. Derue, J. B. Marquette, S. Lupone +11
We present the results of a massive variability search based on a photometric survey of a six square degree region along the Galactic plane at (, ) a…
Blue irregular variable stars in the Small Magellanic Cloud from EROS2 : Herbig Ae/Be or classical Be stars ?
J. P. Beaulieu, W. J. de Wit, H. J. G. M. L. Lamers +6
Using data from the EROS2 microlensing survey, we report the discovery of two blue objects with irregular photometric behaviour of -0.4 mag on time scales of 20 to 200…
Variability and spectral classification of LMC giants: results from DENIS and EROS
M-R. L. Cioni, J-B. Marquette, C. Loup +4
We present the first cross-identifications of sources in the near-infrared DENIS survey and in the micro-lensing EROS survey in a field of about 0.5 square degrees around the optic…
Photometric Constraints on Microlens Spectroscopy of EROS-BLG-2000-5
C. Afonso
We apply EROS photometric data to interpret previously published Keck and VLT spectra of the binary-microlens caustic-crossing event EROS-BLG-2000-5. We show that the VLT data impl…
Not enough stellar mass Machos in the Galactic halo
A. Milsztajn, T. Lasserre
We present an update of results from the search for microlensing towards the Large Magellanic Cloud (LMC) by EROS (Experience de Recherche d'Objets Sombres). We have now monitored…
Not enough stellar Mass Machos in the Galactic Halo
T. Lasserre, EROS Collaboration
We combine new results from the search for microlensing towards the Large Magellanic Cloud (LMC) by EROS2 (Experience de Recherche d'Objets Sombres) with limits previously reported…
EROS2 microlensing search towards the Magellanic Clouds
T. Lasserre, EROS Collaboration
EROS2 is a second generation microlensing experiment operating since mid-1996 at the European Southern Observatory (ESO) at La Silla (Chile). We present the two year analysis from…
Microlensing towards the Small Magellanic Cloud --- EROS 2 two-year analysis
EROS Collaboration
We present the analysis of the first two years of a search for microlensing of stars in the Small Magellanic Cloud with the EROS (Expérience de Recherche d'Objets Sombres) project.…
