X-ray signature of antistars in the Galaxy

  title={X-ray signature of antistars in the Galaxy},
  author={Alexander E. Bondar and Sergey Blinnikov and Andrei Bykov and Aleksander Dolgov and K A Postnov},
The existence of macroscopic objects from antimatter (antistars) is envisaged in some models of baryogenesis. Searches for antistars has been usually carried out in gamma-rays through hadronic annihilation of matter. In astrophysically plausible cases of the interaction of neutral atmospheres or winds from antistars with ionized interstellar gas, the hadronic annihilation will be preceeded by the formation of excited pp and Hep atoms. These atoms rapidly cascade down to low levels prior to… Expand

Gamma-ray spectroscopy of Positron Annihilation in the Milky Way
The annihilation of positrons in the Galaxy's interstellar medium produces characteristic gamma-rays with a line at 511 keV. This emission has been observed with the spectrometer SPI on INTEGRAL,… Expand
The 511 keV emission from positron annihilation in the Galaxy
The first $\ensuremath{\gamma}$-ray line originating from outside the Solar System that was ever detected is the 511 keV emission from positron annihilation in the Galaxy. Despite 30 years of intense… Expand
Antiprotonic Hydrogen: From Atomic Capture to Annihilation
Antiprotons stopping in H2 form antiprotonic hydrogen, atoms of protons and antiprotons bound by their electromagnetic interaction. Antiprotonic hydrogen atoms are formed in high Rydberg states from… Expand

A model of baryogenesis is described which gives rise to fluctuations in baryon number that are large on small scales but of low amplitude on large scales. This provides a mechanism for primordial… Expand
INTEGRAL results on the electron-positron annihilation radiation and X-ray & Gamma-ray diffuse emission of the Milky Way
Abstract This review summarizes INTEGRAL results on two topics: the electron-positron annihilation line and X-ray & Gamma-ray diffuse emission of the Milky Way. The electron-positron annihilation… Expand
Affleck-Dine Baryogenesis and Heavy Element Production from Inhomogeneous Big Bang Nucleosynthesis
Recent observations have revealed that small-scale structure exists at high redshift. We study the possibility of the formation of such structure during baryogenesis and big bang nucleosynthesis. It… Expand
Inhomogeneous baryogenesis, cosmic antimatter, and dark matter
Abstract A model of inhomogeneous baryogenesis based on the Affleck and Dine mechanism is described. A simple coupling of the scalar baryon field to the inflaton allows for formation of… Expand
Where do the AMS-02 antihelium events come from?
We discuss the origin of the anti-helium-3 and -4 events possibly detected by AMS-02. Using up-to-date semi-analytical tools, we show that spallation from primary hydrogen and helium nuclei onto the… Expand
