Companion masses of Gaia DR3 AstroSpectroSB1 binaries: a Bayesian forward-modelling framework
Prasid Sandave, Raghuveer Garani
Gaia Data Release 3 (DR3) has substantially expanded the study of unresolved binaries by providing combined astrometric and spectroscopic orbital solutions for a large sample of no…
Dwarf Galaxy Constraints on Interacting Fermionic Dark Matter
Bihag Dave, Raghuveer Garani
Dwarf galaxies in the Local Group offer a way to test dark matter (DM) models against stellar kinematic data. In this work, we study degenerate fermionic DM in two cases: the stand…
Compact Stars as Portals to Extra-Dimensional Dark Matter
Raghuveer Garani, Chris Kouvaris, Michel H. G. Tytgat +1
We investigate hydrostatic configurations of asymmetric dark matter (DM) spheres in scenarios where fermionic DM can propagate into extra spatial dimensions, while Standard Model f…
Particle production from inhomogeneities: general metric perturbations
Raghuveer Garani, Michele Redi, Andrea Tesi
We present universal formulas for particle production from gravitational inhomogeneities. In the massless limit the result is strikingly simple and completely determined by the two…
Stochastic Dark Matter from Curvature Perturbations
Raghuveer Garani, Michele Redi, Andrea Tesi
We investigate the production of dark matter from curvature perturbations produced during inflation or in standard cosmology, for example during first order phase transitions. Pert…
Dark matter bound-state formation in the Sun
Xiaoyong Chu, Raghuveer Garani, Camilo García-Cely +1
The Sun may capture asymmetric dark matter (DM), which can subsequently form bound-states through the radiative emission of a sub-GeV scalar. This process enables generation of sca…
Could compact stars in globular clusters constrain dark matter?
Raghuveer Garani, Nirmal Raj, Javier Reynoso-Cordova
The dark matter content of globular clusters, highly compact gravity-bound stellar systems, is unknown. It is also generally unknow*able*, due to their mass-to-light ratios typical…
Condensed dark matter with a Yukawa interaction
Raghuveer Garani, Michel H. G. Tytgat, Jérôme Vandecasteele
We explore the possible phases of a condensed dark matter (DM) candidate taken to be in the form of a fermion with a Yukawa coupling to a scalar particle, at zero temperature but a…
Faint light of old neutron stars and detectability at the James Webb Space Telescope
Shiuli Chatterjee, Raghuveer Garani, Rajeev Kumar Jain +3
Isolated ideal neutron stars (NS) of age yrs exhaust thermal and rotational energies and cool down to temperatures below K. Accretion of particle dark ma…
Dark matter self-interactions in the matter power spectrum
Raghuveer Garani, Michele Redi, Andrea Tesi
We study the imprints of secluded dark sectors with a mass gap and self-interactions on the matter power spectrum. When Dark Matter (DM) is sufficiently light, in the ballpark of a…
Solar mass black holes from neutron stars and bosonic dark matter
Raghuveer Garani, Dmitry Levkov, Peter Tinyakov
Black holes with masses cannot be produced via stellar evolution. A popular scenario of their formation involves transmutation of neutron stars - by accumul…
Two-photon exchange in leptophilic dark matter scenarios
Raghuveer Garani, Federico Gasparotto, Pierpaolo Mastrolia +3
In leptophilic scenarios, dark matter interactions with nuclei, relevant for direct detection experiments and for the capture by celestial objects, could only occur via loop-induce…
Dark QCD Matters
Raghuveer Garani, Michele Redi, Andrea Tesi
We investigate the nightmare scenario of dark sectors that are made of non-abelian gauge theories with fermions, gravitationally coupled to the Standard Model (SM). While testing t…
Evaporation of dark matter from celestial bodies
Raghuveer Garani, Sergio Palomares-Ruiz
Scatterings of galactic dark matter (DM) particles with the constituents of celestial bodies could result in their accumulation within these objects. Nevertheless, the finite tempe…
Observing the thermalization of dark matter in neutron stars
Raghuveer Garani, Aritra Gupta, Nirmal Raj
A promising probe to unmask particle dark matter is to observe its effect on neutron stars, the prospects of which depend critically on whether captured dark matter thermalizes in…
Constraints on Dark Matter from the Moon
Raghuveer Garani, Peter Tinyakov
New and complimentary constraints are placed on the spin-independent interactions of dark matter with baryonic matter. Similar to the Earth and other planets, the Moon does not hav…
Dark matter interactions with muons in neutron stars
Raghuveer Garani, Julian Heeck
Neutron stars contain a significant number of stable muons due to the large chemical potential and degenerate electrons. This makes them the unique vessel to capture muonphilic dar…
New Analysis of Neutron Star Constraints on Asymmetric Dark Matter
Raghuveer Garani, Yoann Genolini, Thomas Hambye
Due to their extreme density and low temperature, neutron stars (NS) are efficient probes to unveil interactions between standard model and dark matter (DM) particles. From elastic…
Dark matter in the Sun: scattering off electrons vs nucleons
Raghuveer Garani, Sergio Palomares-Ruiz
The annihilation of dark matter (DM) particles accumulated in the Sun could produce a flux of neutrinos, which is potentially detectable with neutrino detectors/telescopes and the…
Sgoldstino search at the LHC
Masaki Asano, Raghuveer Garani
Low-scale supersymmetry breaking scenario in which the breaking scale is around TeV has been discussed as a possibility to obtain a large Higgs mass and to moderate the fine tuning…
Systematic uncertainties from halo asphericity in dark matter searches
Nicolas Bernal, Jaime E. Forero-Romero, Raghuveer Garani +1
Although commonly assumed to be spherical, dark matter halos are predicted to be non-spherical by N-body simulations and their asphericity has a potential impact on the systematic…
