Dark matter (DM) makes up most of the mass of the Universe but remains mysterious. I discuss recent progress in constraining its properties through its gravitational influence. I show that the latest constraints from dwarf galaxies, galaxy clusters and the cosmic microwave background rule out weak-field alternative gravity explanations for DM, favouring a new, cold, collisionless, particle...

In this talk, I will explore the interfacing of simulations, observations, and machine learning techniques to constrain the distribution of Dark Matter for indirect detection. I will focus on the Galactic Center and dwarf galaxies as laboratories for Dark Matter detection. For the Galactic Center, I will show how we can combine the theoretical understanding of adiabatic contraction with bursty...

Just like light, gravitational waves (GWs) are gravitationally lensed by massive objects in the Universe. Moreover, their low frequency, phase coherence, and lack of absorption make GWs complementary to lensed electromagnetic sources. In addition to gravitational magnification and the formation of multiple images, lensed GWs exhibit genuine wave-propagation effects such as diffraction, i.e.,...

The large-scale structure (LSS) of the Universe has traditionally been mapped through galaxy surveys. The third generation (3G) of gravitational wave (GW) detectors, such as the Einstein Telescope and Cosmic Explorer, will provide an independent probe for LSS using compact binary mergers as tracers of the underlying matter distribution in the Universe. In the 3G era, we will be able to measure...

Certain asymmetric dark matter candidates can accumulate in neutron star cores and trigger their collapse into low-mass black holes. If this process occurs in compact binaries, the Universe may contain distinct populations of binary neutron stars and low-mass binary black holes. Gravitational-wave observations can distinguish these populations through their tidal deformabilities, which vanish...

Light scalar particles arise naturally in many extensions of the standard model and are compelling dark-matter candidates. Gravitational interactions near black holes can trigger the growth of dense scalar configurations that, if sustained during inspiral, alter binary dynamics and imprint signatures on gravitational-wave signals. I will describe how numerical relativity simulations can...

Gravitational wave observations have opened a direct route to studying black hole (BH) populations. In principle, primordial and astrophysical BHs may be distinguishable through their mass, spin, redshift, and merger-rate distributions. At the same time, the observed BH population provides a new probe of nuclear and particle physics in stellar cores. A major obstacle is that the late evolution...

I will discuss how understanding the Nanograv observations has led us to focus on the growth of supermassive black holes in the early Universe, and how understanding how this has taken place, together with observations from JWST, have led us to new constraints on the nature of dark matter.

The Sun and other nearby stars can act as powerful probes of particle dark matter, thanks to precision observations. However, because the effect of dark matter is small, we must be certain that our modelling of the effect of dark matter and the stellar response is correct. I will discuss recent developments on modelling the subtle effects of dark matter, with some focus on helio- and asteroseismology.

Neutron stars provide unique laboratories for probing fundamental physics under extreme conditions of density, gravity, and magnetic field strength. In this talk, I will review several intriguing aspects of axions, ALPs and other well-motivated dark matter candidates in the ultradense and strongly magnetized interiors and magnetosphere of neutron stars. As complementary indirect probes of the...

Dark matter that propagates in extra dimensions can substantially soften the equation of state and lead to collapse of dark matter inside neutron stars, eventually destroying the host star. Based on that scenario constraints can be drawn on extra-dimensional dark matter.

I will review the programme of Dark Matter searches at the LHC from EFT approaches to simplified models and beyond, discussing the complementarity with direct/indirect searches and the connection to searches for hidden sectors.

MeV scale axion-like particles can be produced with semi-relativistic velocities in Galactic supernovae, leading to a diffuse flux that can be detectable in neutrino water-Cherenkov detectors. This is possible through their absorption on free protons, ap→pγ, where the resulting photon has approximately the energy of the ALP. This new signature is complementary to the usual one from oxygen...
