Analysis
This paper explores the observational signatures of oscillatons, a type of dark matter candidate. It investigates how the time-dependent nature of these objects, unlike static boson stars, could lead to observable effects, particularly in the form of a 'twinkling' behavior in the light profiles of accretion disks. The potential for detection by instruments like the Event Horizon Telescope is a key aspect.
Key Takeaways
- •Oscillatons are time-dependent dark matter structures.
- •They could produce a 'twinkling' effect in the light from accretion disks.
- •This effect might be detectable by the Event Horizon Telescope.
- •The oscillation frequency is related to the scalar field mass.
Reference
“The oscillatory behavior of the redshift factor has a strong effect on the observed intensity profiles from accretion disks, producing a breathing-like image whose frequency depends on the mass of the scalar field.”
