Description
Scalar field dark matter (SFDM) is an alternative candidate to standard
dark matter models, gaining attention due to the unique effects
associated with its ultra-light mass. While its dynamics have been
extensively studied across different scales, its full phenomenology
remains under active investigation. In particular, the role of
self-interactions and their impact on structure formation are still open
questions. In this talk, I will explore the effects of both attractive
and repulsive self-interactions in SFDM, with a focus on the evolution
of the mass fraction and the core-halo relation. I will discuss
analytical models proposed in the literature to describe dark matter
halo cores and compare them with results from three-dimensional
simulations. These findings will provide a basis for establishing
comparisons between theoretical predictions and observational data,
allowing us to impose constraints on the self-interaction term.
