Milky Way White Dwarfs as Inelastic Dark Matter Detectors
Javier F. Acevedo
We show that white dwarfs in the Galactic Center are a sensitive probe of inelastic dark matter (IDM) annihilation. IDM particles traversing a white dwarf may become gravitationall…
Boosted Dark Matter from Sagittarius A
Javier F. Acevedo, Adam Ritz
It was recently demonstrated that black hole binaries can gravitationally accelerate ambient dark matter (DM), producing a continuous flux of particles with velocities far exceedin…
Binary-boosted Dark Matter
Javier F. Acevedo, Adam Ritz
We explore the aggregate effect of binary systems on the Milky Way's dark matter (DM) velocity distribution with Monte Carlo simulations. Through gravitational interactions with bi…
Dark Drag Around Sagittarius A*
Javier F. Acevedo, Aidan J. Reilly, Lillian Santos-Olmsted
We analyze the effect of Dark Matter (DM) - Standard Model (SM) non-gravitational interactions on the orbital dynamics of celestial bodies near the supermassive black hole Sagittar…
Sub-MHz Radio Background from Ultralight Dark Photon Dark Matter
Javier F. Acevedo, Amit Bhoonah, Kun Cheng
Dark photons are a well-motivated candidate for dark matter, but their detection becomes challenging for ultralight masses with both experimental and astrophysical probes. In this…
Loosely Bound Composite Dark Matter
Javier F. Acevedo, Yilda Boukhtouchen, Joseph Bramante +3
We investigate loosely bound composite states made of dark matter, where the binding energy for constituent particles is less than the constituent mass. We focus on models of nucle…
Dark Matter Raining on DUNE and Other Large Volume Detectors
Javier F. Acevedo, Joshua Berger, Peter B. Denton
Direct detection is a powerful means of searching for particle physics evidence of dark matter (DM) heavier than about a GeV with volume, low-threshold detect…
Dark Kinetic Heating of Exoplanets and Brown Dwarfs
Javier F. Acevedo, Rebecca K. Leane, Aidan J. Reilly
Dark kinetic heating of neutron stars has been previously studied as a promising dark matter detection avenue. Kinetic heating occurs when dark matter is sped up to relativistic sp…
Neutrino and Gamma-Ray Signatures of Inelastic Dark Matter Annihilating outside Neutron Stars
Javier F. Acevedo, Joseph Bramante, Qinrui Liu +1
We present a new inelastic dark matter search: neutron stars in dark matter-rich environments capture inelastic dark matter which, for interstate mass splittings between about $45…
Milky Way White Dwarfs as Sub-GeV to Multi-TeV Dark Matter Detectors
Javier F. Acevedo, Rebecca K. Leane, Lillian Santos-Olmsted
We show that Milky Way white dwarfs are excellent targets for dark matter (DM) detection. Using Fermi and H.E.S.S. Galactic center gamma-ray data, we investigate sensitivity to DM…
Dark Matter-Induced Baryonic Feedback in Galaxies
Javier F. Acevedo, Haipeng An, Yilda Boukhtouchen +3
We demonstrate that non-gravitational interactions between dark matter and baryonic matter can affect structural properties of galaxies. Detailed galaxy simulations and analytic es…
Evaporation Barrier for Dark Matter in Celestial Bodies
Javier F. Acevedo, Rebecca K. Leane, Juri Smirnov
The minimum testable dark matter (DM) mass for almost all DM signatures in celestial bodies is determined by the rate at which DM evaporates. DM evaporation has previously been cal…
Mineral Detection of Neutrinos and Dark Matter. A Whitepaper
Sebastian Baum, Patrick Stengel, Natsue Abe +66
Minerals are solid state nuclear track detectors - nuclear recoils in a mineral leave latent damage to the crystal structure. Depending on the mineral and its temperature, the dama…
Diffuse X-Ray and Gamma-Ray Limits on Boson Stars that Interact with Nuclei
Javier F. Acevedo, Amit Bhoonah, Joseph Bramante
Light bosonic dark matter can form gravitationally bound states known as boson stars. In this work, we explore a new signature of these objects interacting with the interstellar me…
Accelerating Composite Dark Matter Discovery with Nuclear Recoils and the Migdal Effect
Javier F. Acevedo, Joseph Bramante, Alan Goodman
Large composite dark matter states source a scalar binding field that, when coupled to Standard Model nucleons, provides a potential under which nuclei recoil and accelerate to ene…
Old Rocks, New Limits: Excavated Ancient Mica Searches For Dark Matter
Javier F. Acevedo, Joseph Bramante, Alan Goodman
Minerals excavated from the Earth's crust contain gigayear-long astroparticle records, which can be read out using acid etching and microscopy, providing unmatched sensitivity to h…
Nuclear Fusion Inside Dark Matter
Javier F. Acevedo, Joseph Bramante, Alan Goodman
A new dynamic is identified between dark matter and nuclei. Nuclei accelerated to MeV energies by the internal potential of composite dark matter can undergo nuclear fusion. This e…
Dark Matter, Destroyer of Worlds: Neutrino, Thermal, and Existential Signatures from Black Holes in the Sun and Earth
Javier F. Acevedo, Joseph Bramante, Alan Goodman +2
Dark matter can be captured by celestial objects and accumulate at their centers, forming a core of dark matter that can collapse to a small black hole, provided that the annihilat…
Warming Nuclear Pasta with Dark Matter: Kinetic and Annihilation Heating of Neutron Star Crusts
Javier F. Acevedo, Joseph Bramante, Rebecca K. Leane +1
Neutron stars serve as excellent next-generation thermal detectors of dark matter, heated by the scattering and annihilation of dark matter accelerated to relativistic speeds in th…
Supernovae Sparked By Dark Matter in White Dwarfs
Javier F. Acevedo, Joseph Bramante
It was recently demonstrated that asymmetric dark matter can ignite supernovae by collecting and collapsing inside lone sub-Chandrasekhar mass white dwarfs, and that this may be th…
