Swampland Revisited
Michel Cass\e', Joseph Silk
The transcendental expectation of string theory is that the nature of the fundamental forces, particle spectra and masses, together with coupling constants, is uniquely determined…
New constraints on the primordial black hole number density from Galactic gamma-ray astronomy
R. Lehoucq, M. Casse, J. -M. Casandjian +1
Primordial black holes are unique probes of cosmology, general relativity, quantum gravity and non standard particle physics. They can be considered as the ultimate particle accele…
Constraints on the injection energy of positrons in the Galactic centre region
Patrick Sizun, Michel Cassé, Stéphane Schanne +1
Recent observations of the 511 keV positron-electron annihilation line in the Galactic centre region by the INTEGRAL/SPI spectrometer have stirred up new speculations about the ori…
Type Ia Supernova Rate in the Galactic Center Region
Stephane Schanne, Michel Casse, Patrick Sizun +2
According to recent analyses of the type-Ia supernova rate as a function of redshift, delayed and prompt type-Ia supernovae (SN Ia) should explode respectively in the Galactic bulg…
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…
Light Dark Matter
Michel Casse, Pierre Fayet
The SPI spectrometer aboard of the INTEGRAL satellite has released a map of the e+e- annihilation emission line of unprecedented quality, showing that most of the photons arise fro…
