Type Ia supernova rate at
D. Hardin, C. Afonso, C. Alard +44
We present the EROS nearby supernova () search and the analysis of the first year of data (1997). A total of 80 square degrees were surveyed. Eight supernovæ we…
Discovery of a peculiar Cepheid-like star towards the northern edge of the Small Magellanic Cloud
J. B. Marquette, P. Tisserand, P. Francois +37
For seven years, the EROS-2 project obtained a mass of photometric data on variable stars. We present a peculiar Cepheid-like star, in the direction of the Small Magellanic Cloud,…
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…
The beat Cepheids in the Magellanic Clouds: an analysis from the EROS-2 database
J. B. Marquette, J. P. Beaulieu, J. R. Buchler +36
A number of microlensing dark-matter surveys have produced tens of millions of light curves of individual background stars. These data provide an unprecedented opportunity for syst…
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…
The EROS2 search for microlensing events towards the spiral arms: the complete seven season results
Y. R. Rahal, C. Afonso, J. -N. Albert +36
The EROS-2 project has been designed to search for microlensing events towards any dense stellar field. The densest parts of the Galactic spiral arms have been monitored to maximiz…
Galactic Bulge Microlensing Optical Depth from EROS-2
C. Hamadache, L. Le Guillou, P. Tisserand +34
We present a new EROS-2 measurement of the microlensing optical depth toward the Galactic Bulge. Light curves of clump-giant stars distributed over of…
