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…
New limits from microlensing on Galactic Black Holes in the mass range
T. Blaineau, M. Moniez, C. Afonso +17
We have searched for long duration microlensing events originating from intermediate mass Black Holes (BH) in the halo of the Milky Way, using archival data from EROS-2 and MACHO p…
Gamma-ray emission in alpha-particle reactions with C, Mg, Si, Fe
J. Kiener, J. Bundesmann, I. Deloncle +10
Cross sections for the strongest gamma-ray emission lines produced in alpha-particle reactions with C, Mg, Si, Fe have been measured in the range E_alpha = 50 - 90 MeV at the cente…
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 e-ASTROGAM gamma-ray space observatory for the multimessenger astronomy of the 2030s
V. Tatischeff, A. De Angelis, M. Tavani +74
e-ASTROGAM is a concept for a breakthrough observatory space mission carrying a gamma-ray telescope dedicated to the study of the non-thermal Universe in the photon energy range fr…
Gamma-ray production cross sections in proton interactions with natMg, natSi and 56Fe targets: measurement over the energy range of -125 MeV, data analysis, results and discussion. Astrophysical implications
M. Debabi, S. Ouichaoui, A. Belhout +34
We have measured nuclear gamma-ray line production cross sections in interactions of highly accelerated proton beams with various target nuclei abundant in astrophysical sites. The…
