The existence and detection of scalar fields could provide solutions to long- standing puzzles about the nature of dark matter, the dark compact objects at the centre of most galaxies, and other phenomena. Yet, self-interacting scalar fields are very poorly constrained by astronomical observations, leading to great uncertainties in estimates of the mass mand the self-interacting coupling constantof these fields. To counter this, we have systematically employed available astronomical… Expand

Probing dynamics of boson stars by fast radio bursts and gravitational wave detection
Boson stars may consist of a new type of light singlet scalar particles with nontrivial self-interactions, and may compose a fraction of the dark matter in the Universe. In this work, we study theExpand

Precise measurements of the S-stars orbiting SgrA* have set strong constraints on the nature of the compact object at the centre of the Milky Way. The presence of a black hole in that region isExpand

Classical scalar fields have been proposed as possible candidates for the dark matter component of the universe. Given the fact that supermassive black holes seem to exist at the center of mostExpand
Ruling Out Bosonic Repulsive Dark Matter
Self-interacting dark matter, especially bosonic, has been considered a promising candidate to replace cold dark matter (CDM) as it resolves some of the problems associated with CDM. Here, we ruleExpand

At the dawn of a golden age for gravitational wave astronomy, we must leave no stone unturned in our quest for new phenomena beyond our current understanding of General Relativity (GR), particleExpand

Relativistic dynamics and extreme mass ratio inspirals
A unique probe of these regions is the gravitational radiation emitted by some compact stars very close to the black holes and which could be surveyed by a millihertz gravitational-wave interferometer scrutinizing the range of masses fundamental to understanding the origin and growth of supermassive black holes.

Galactic halos of fluid dark matter
Dwarf spiral galaxies - and in particular the prototypical DDO 154 - are known to be completely dominated by an unseen component. The putative neutralinos - so far the favored explanation for theExpand
Dark Halos: The Flattening of the Density Cusp by Dynamical Friction
N-body simulations and analytical calculations of the gravitational collapse in an expanding universe predict that halos should form with a diverging inner density profile, the cusp. There are someExpand
Cosmological constraints on quintessential halos
A complex scalar field has recently been suggested to bind galaxies and flatten the rotation curves of spirals. Its cosmological behavior is thoroughly investigated here. Such a field is shown to beExpand
Flat central density profiles from scalar field dark matter halos
Scalar elds endowed with a cosh potential behave in the linear regime, exactly as the cold dark matter (CDM) model. Thus, the scalar eld dark matter (SFDM) hypothesis predicts the same structureExpand

General relativistic boson stars
There is accumulating evidence that (fundamental) scalar fields may exist in nature. The gravitational collapse of such a boson cloud would lead to a boson star (BS) as a new type of a compactExpand
The removal of cusps from galaxy centres by stellar feedback in the early Universe
Numerical simulations show that random bulk motions of gas in small primordial galaxies will result in a flattening of the central dark matter cusp on relatively short timescales (∼108 years), which would have operated in all star-forming galaxies at redshifts z ≥ 10. Expand
