A Simulated Galaxy Produces Excesses Larger Than Fermi's
Time-dependent cosmic-ray transport created transient gamma-ray residuals whose spectrum and shape sometimes resembled the Galactic Center excess.
Summary
Time-dependent cosmic-ray transport created transient gamma-ray residuals whose spectrum and shape sometimes resembled the Galactic Center excess.
The authors argue the excess may reflect a look-elsewhere fluctuation in diffuse stellar-source emission and call for time-dependent templates. Simulated resemblance does not rule out dark matter or unresolved pulsars.
Why it matters
Time-dependent cosmic-ray transport created transient gamma-ray residuals whose spectrum and shape sometimes resembled the Galactic Center excess.
Limits and context
- Simulated resemblance does not rule out dark matter or unresolved pulsars.
Key claims
Time-dependent cosmic-ray transport created transient gamma-ray residuals whose spectrum and shape sometimes resembled the Galactic Center excess.
Qualification: Simulated resemblance does not rule out dark matter or unresolved pulsars.
