Galactic magnetic fields seeded by ultralight dark photons
Joshua Berger, Amit Bhoonah, Joseph Bramante +3
In this work, we show that ultralight dark photons, which couple to the Standard Model photon through kinetic mixing, can potentially source galactic scale magnetic fields. Althoug…
Secluded Dark Composites and Remnant Binding Fields
Katarina Bleau, Yilda Boukhtouchen, Joseph Bramante +1
Dark matter may freeze-out and undergo composite assembly while decoupled from the Standard Model. In this secluded composite scenario, while individual dark matter particles may b…
Dark Matter Candidates and Searches
Nassim Bozorgnia, Joseph Bramante, James M. Cline +7
Astrophysical observations suggest that most of the matter in the cosmos consists of a new form that has not been observed on Earth. The nature and origin of this mysterious dark m…
Dimming Starlight with Dark Compact Objects
Joseph Bramante, Melissa D. Diamond, J. Leo Kim
We demonstrate a new technique to search for dark compact objects. When dark matter comprising a dark compact object interacts with photons, the compact object can disperse light t…
Resonant or asymmetric: The status of sub-GeV dark matter
Sowmiya Balan, Csaba Balázs, Torsten Bringmann +9
Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the strong constraints on heavier DM candidates but at the same time face a multitude of new constr…
Dissipative Dark Cosmology: From Early Matter Dominance to Delayed Compact Objects
Joseph Bramante, Christopher V. Cappiello, Melissa D. Diamond +3
We demonstrate a novel mechanism for producing dark compact objects and black holes through a dark sector, where all the dark matter can be dissipative. Heavy dark sector particles…
A Global Fit of Non-Relativistic Effective Dark Matter Operators Including Solar Neutrinos
Neal P. Avis Kozar, Pat Scott, Aaron C. Vincent
We perform a global fit of dark matter interactions with nucleons using a non-relativistic effective operator description, considering both direct detection and neutrino data. We e…
The Effect of Multiple Cooling Channels on the Formation of Dark Compact Objects
Joseph Bramante, Melissa Diamond, J. Leo Kim
A dissipative dark sector can result in the formation of compact objects with masses comparable to stars and planets. In this work, we investigate the formation of such compact obj…
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…
A Hybrid Type I + III Inverse Seesaw Mechanism in -symmetric MSSM
Cem Murat Ayber, Seyda Ipek
We show that, in a -symmetric supersymmetric model, the pseudo-Dirac bino and wino can give rise to three light neutrino masses through effective operators, generated a…
The Morphology of Exciting Dark Matter and the Galactic 511 keV Signal
Christopher V. Cappiello, Michael Jafs, Aaron C. Vincent
We study the morphology of the 511 keV signal that could be produced by exciting dark matter (XDM) in the Milky Way. In this model, collisions between dark matter particles excite…
Multimessenger Constraints on Radiatively Decaying Axions from GW170817
Melissa Diamond, Damiano F. G. Fiorillo, Gustavo Marques-Tavares +2
The metastable hypermassive neutron star produced in the coalescence of two neutron stars can copiously produce axions that radiatively decay into ~MeV photons. T…
Axion-sourced fireballs from supernovae
Melissa Diamond, Damiano F. G. Fiorillo, Gustavo Marques-Tavares +1
New feebly interacting particles would emerge from a supernova core with 100-MeV-range energies and produce -rays by subsequent decays. These would contribute to the diffuse cos…
An Analytic Approach to Light Dark Matter Propagation
Christopher Cappiello
If dark matter interacts too strongly with nuclei, it could be slowed to undetectable speeds in Earth's crust or atmosphere before ever reaching a detector. For sub-GeV dark matter…
Supermassive black hole seeds from sub-keV dark matter
Avi Friedlander, Sarah Schon, Aaron C. Vincent
Quasars observed at redshifts are powered by supermassive black holes which are too large to have grown from early stellar remnants without efficient super-Eddington…
Dark Matter from Monogem
Christopher V. Cappiello, Neal P. Avis Kozar, Aaron C. Vincent
As a supernova shock expands into space, it may collide with dark matter particles, scattering them up to velocities more than an order of magnitude larger than typical dark matter…
New Constraints on Macroscopic Dark Matter Using Radar Meteor Detectors
Pawan Dhakal, Steven Prohira, Christopher V. Cappiello +3
We show that dark-matter candidates with large masses and large nuclear interaction cross sections are detectable with terrestrial radar systems. We develop our results in close co…
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…
Primordial Black Hole Dark Matter in the Context of Extra Dimensions
Avi Friedlander, Katherine J. Mack, Sarah Schon +2
Theories of large extra dimensions (LEDs) such as the Arkani-Hamed, Dimopoulos & Dvali scenario predict a "true" Planck scale near the TeV scale, while the observed $M_{p…
Simulation of energy transport by dark matter scattering in stars
Hannah Banks, Siyam Ansari, Aaron C. Vincent +1
Asymmetric dark matter (ADM) that is captured in stars can act as an efficient conductor of heat. Small ADM-induced changes in a star's temperature gradient are known to alter neut…
Scattering searches for dark matter in subhalos: neutron stars, cosmic rays, and old rocks
Joseph Bramante, Bradley J. Kavanagh, Nirmal Raj
In many cosmologies dark matter clusters on sub-kiloparsec scales and forms compact subhalos, in which the majority of Galactic dark matter could reside. Null results in direct det…
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…
Thermal WIMPs and the Scale of New Physics: Global Fits of Dirac Dark Matter Effective Field Theories
The GAMBIT Collaboration, Peter Athron, Neal Avis Kozar +24
We assess the status of a wide class of WIMP dark matter (DM) models in light of the latest experimental results using the global fitting framework . We perform a…
Pushing the frontier of WIMPy inelastic dark matter: journey to the end of the periodic table
Ningqiang Song, Serge Nagorny, Aaron C. Vincent
We explore the reach of low-background experiments made of small quantities of heavy nuclear isotopes in probing the parameter space of inelastic dark matter that is kinematically…
