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…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Coupled Time-Dependent Proton Acceleration and Leptonic-Hadronic Radiation in Turbulent Supermassive Black Hole Coronae
Chengchao Yuan, Damiano F. G. Fiorillo, Maria Petropoulou +1
Turbulent coronae of supermassive black holes can accelerate non-thermal particles to high energies and produce observable radiation, but capturing this process is challenging due…
Modeling Gravitational Wave Bias from 3D Power Spectra of Spectroscopic Surveys
Dorsa Sadat Hosseini, Amir Dehghani, J. Leo Kim +3
We present a framework for relating gravitational wave (GW) sources to the astrophysical properties of spectroscopic galaxy samples. We show how this can enable using clustering me…
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…
Position Reconstruction in the DEAP-3600 Dark Matter Search Experiment
The DEAP Collaboration, P. Adhikari, R. Ajaj +162
In the DEAP-3600 dark matter search experiment, precise reconstruction of the positions of scattering events in liquid argon is key for background rejection and defining a fiducial…
WALLABY Pilot Survey & ASymba: Comparing HI Detection Asymmetries to the SIMBA Simulation
Mathieu Perron-Cormier, Nathan Deg, Kristine Spekkens +15
An avenue for understanding cosmological galaxy formation is to compare morphometric parameters in observations and simulations of galaxy assembly. In this second paper of the ASym…
Seeking the nearest neutron stars using a new local electron density map
Joseph Bramante, Katherine Mack, Nirmal Raj +2
Neutron stars provide a compelling testing ground for gravity, nuclear dynamics, and physics beyond the Standard Model, and so it will be useful to locate the neutron stars nearest…
The Gravitational Wave Bias Parameter from Angular Power Spectra: Bridging Between Galaxies and Binary Black Holes
Amir Dehghani, J. Leo Kim, Dorsa Sadat Hosseini +3
This study presents the modeling of the gravitational wave (GW) bias parameter by bridging a connection between simulated GW sources and galaxies in low redshift galaxy surveys 2MP…
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…
Simultaneous Measurement of Half-Life and Spectral Shape of In -decay with an Indium Iodide Cryogenic Calorimeter
L. Pagnanini, G. Benato, P. Carniti +21
Current bounds on neutrino Majorana mass are affected by significant uncertainties in the nuclear calculations for neutrinoless double-beta decay. A key issue for a data-driven imp…
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…
Instability and backreaction of massive spin-2 fields around black holes
William E. East, Nils Siemonsen
A massive spin-2 field can grow unstably around a black hole, giving rise to a potential probe of the existence of such fields. In this work, we use time-domain evolutions to study…
Exploring the Potential of the Pulsed Laser onboard the CALIPSO Satellite to Improve Calibration with VERITAS
Gregory Foote
Imaging Atmospheric Cherenkov Telescopes (IACTs) are used to detect bright nanosecond-duration flashes of optical light originating from interactions of cosmic/gamma-rays in the at…
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…
A VERITAS/Breakthrough Listen Search for Optical Technosignatures
Atreya Acharyya, Colin Adams, Avery Archer +65
The Breakthrough Listen Initiative is conducting a program using multiple telescopes around the world to search for "technosignatures": artificial transmitters of extraterrestrial…
Generic initial data for binary boson stars
Nils Siemonsen, William E. East
Binary boson stars can be used to model the nonlinear dynamics and gravitational wave signals of merging ultracompact, but horizonless, objects. However, doing so requires initial…
