Simulation-Informed High-Velocity Dark Matter in the Effective Theory of Direct Detection
Xiuyuan Zhang, Gonzalo Herrera, Andreas Thoyas +1
The interpretation and reach of direct detection (DD) experiments depend sensitively on the local dark matter (DM) velocity distribution, particularly its high-velocity tail. This…
Dark Photons from Perturbative Decay of a Misaligned Higgs Field
James M. Cline, Gonzalo Herrera, Jean-Samuel Roux
We reconsider the production of dark photons as dark matter, from the perturbative decay of a dark Higgs field , that is stochastically misaligned from the minimum of its p…
Scale-Invariant Open Quantum Systems
Carlos Argüelles, Gabriela Barenboim, Gonzalo Herrera +2
We develop a complete theoretical framework for open quantum systems coupled to scale-invariant environments. We show that such environments are universally described by unparticle…
Neutrinos as Dark Matter
James M. Cline, Gonzalo Herrera, Jean-Samuel Roux
Active neutrinos in standard cosmology were ruled out as a dark matter candidate in the 1980's. The reason is twofold: they are too light to account for the observed energy density…
Dark Matter-Electron Interactions Alter the Luminosity and Spectral Index of M87
Abdelaziz Hussein, Gonzalo Herrera
We investigate the possibility that cosmic-ray electron cooling through dark matter-electron scatterings contributes to the low radiative efficiency observed in radio-loud galaxies…
High-Energy Neutrinos from Cosmic-Ray Scatterings with Supernova Neutrinos
Gonzalo Herrera, Shunsaku Horiuchi
Cosmic rays scattering with neutrinos produced in supernovae induce a flux of supernova neutrinos boosted to high energies. We calculate the neutrino flux arising from this new mec…
The Highest-Energy Neutrino Event Constrains Dark Matter-Neutrino Interactions
Toni Bertólez-Martínez, Gonzalo Herrera, Pablo Martínez-Miravé +1
Dark Matter-neutrino interactions affect the propagation of astrophysical neutrinos, attenuating the flux of neutrinos arriving at Earth. Using the highest-energy neutrino event de…
The Dark Matter Diffused Supernova Neutrino Background
Garv Chauhan, R. Andrew Gustafson, Gonzalo Herrera +2
We consider neutrinos scattering off Milky Way dark matter and the impact of this scattering on supernovae neutrinos. This can take the form of attenuation on the initial flux of n…
Plausible Indication of Gamma-Ray Absorption by Dark Matter in NGC 1068
Gonzalo Herrera
NGC 1068 is the brightest extragalactic source in high-energy neutrinos as seen by IceCube, yet the accompanying gamma-ray flux is orders of magnitude weaker. It has been argued th…
Neutrino Diffusion within Dark Matter Spikes
Motoko Fujiwara, Gonzalo Herrera, Shunsaku Horiuchi
Multi-messenger observations of astrophysical transients provide powerful probes of the underlying physics of the source as well as beyond the Standard Model effects. We explore tr…
Plausible constraints and inflationary production for dark photons
James M. Cline, Gonzalo Herrera
Generic constraints on dark photons are generally presented assuming they have Stueckelberg masses. These constraints are strengthened if instead the mass is due to the Higgs mecha…
Cosmic-Ray Cooling in Active Galactic Nuclei as a New Probe of Inelastic Dark Matter
R. Andrew Gustafson, Gonzalo Herrera, Mainak Mukhopadhyay +2
We present a novel way to probe inelastic dark matter using cosmic-ray (CR) cooling in active galactic nuclei (AGNs). Dark matter (DM) in the vicinity of supermassive black holes m…
Tidal Disruption Events and Dark Matter Scatterings with Neutrinos and Photons
Motoko Fujiwara, Gonzalo Herrera
Stars can be tidally disrupted when passing near a black hole, and the debris can induce a flux of high-energy neutrinos. It has been discussed that there are hints in IceCube data…
