Solar Neutrino Constraints on Inelastic Dark Matter Scattering in Light of Recent LUX-ZEPLIN Observations
Thong T. Q. Nguyen, Tim Linden, Dan Hooper
The LUX-ZEPLIN (LZ) Collaboration recently reported the detection of a single nuclear recoil candidate event with a very high recoil energy. The lack of any corresponding low-energ…
Strong Constraints on Line Signals from Dark Matter Annihilation in a Nearby Subhalo
Asier Salces Pérez, Thong T. Q. Nguyen, Pedro De la Torre Luque +1
We present a dedicated search for monochromatic gamma-ray emission from a recently proposed nearby dark matter subhalo candidate. Using nearly 15 years of Fermi-LAT Pass 8 data, we…
Solar Spin-Dependent Dark Matter-Neutron Cross Section Constraints: The Lost Case
Thong T. Q. Nguyen, Carlos Blanco, Tim Linden
The Sun has long served as a natural dark matter detector, capturing halo particles that scatter with solar nuclei and electrons and subsequently produce indirect signals from dark…
Towards Quantum-Dot Detectors as Barcodes for Dark Matter Interactions
Marek Matas, Andrea Gallo Rosso, Antonio Cammarata +6
Quantum dots are tunable semiconductor nanocrystals that can be produced at industrial scales. We present the first ab initio calculation of the scattering of dark matter on electr…
The Sun Can Strongly Constrain Spin-Dependent Dark Matter Nucleon Scattering Below the Evaporation Limit
Thong T. Q. Nguyen, Tim Linden
The Sun is a promising target for dark matter (DM) searches due to its ability to accumulate DM particles via scattering and catalyze their self-annihilation. However, at low DM ma…
Dark matter silences Cepheids in the Galactic Center
Djuna Croon, Tim Linden, Jeremy Sakstein
Upcoming near-infrared facilities (e.g. JWST/NIRCam, ELT/MICADO) will dramatically increase the detectability of galactic center Cepheids despite extreme extinction at optical wave…
INTEGRAL, eROSITA and Voyager Constraints on Light Bosonic Dark Matter: ALPs, Dark Photons, Scalars, and Vectors
Thong T. Q. Nguyen, Pedro De la Torre Luque, Isabelle John +3
The decay of light bosonic dark matter particles can produce a bright electron/positron () flux that can be strongly constrained by local Voyager observations of the direct…
Strong Constraints on Dark Photon and Scalar Dark Matter Decay from INTEGRAL and AMS-02 data
Thong T. Q. Nguyen, Isabelle John, Tim Linden +1
We investigate the decay of bosonic dark matter with masses between 1 MeV and 2 TeV into Standard Model final states. We specifically focus on dark photons that kinetically mix wit…
X-Ray Constraints on Dark Photon Tridents
Tim Linden, Thong T. Q. Nguyen, Tim M. P. Tait
Dark photons that are sufficiently light and/or weakly-interacting represent a compelling vision of dark matter. Dark photon decay into three photons, which we call the dark photon…
Indirect Searches for Dark Photon-Photon Tridents in Celestial Objects
Tim Linden, Thong T. Q. Nguyen, Tim M. P. Tait
We model and constrain the unique indirect detection signature produced by dark matter particles that annihilate through a gauge symmetry into dark photons that subsequently…
Gamma-Ray Lines in 15 Years of Fermi-LAT Data: New Constraints on Higgs Portal Dark Matter
Pedro De La Torre Luque, Juri Smirnov, Tim Linden
Monoenergetic -ray spectral lines are among the cleanest signatures of dark matter annihilation. We analyze 15 years of Fermi-LAT data, find no spectral lines, and place strong…
Accurate Inverse-Compton Models Strongly Enhance Leptophilic Dark Matter Signals
Isabelle John, Tim Linden
The annihilation of TeV-scale leptophilic dark matter into electron-positron pairs (hereafter ) will produce a sharp cutoff in the local cosmic-ray spectrum at an…
Cosmic Ray Antihelium from a Strongly Coupled Dark Sector
Martin Wolfgang Winkler, Pedro De La Torre Luque, Tim Linden
Standard Model extensions with a strongly coupled dark sector can induce high-multiplicity states of soft quarks. Such final states trigger extremely efficient antinucleus formatio…
Snowmass2021 Cosmic Frontier White Paper: Puzzling Excesses in Dark Matter Searches and How to Resolve Them
Rebecca K. Leane, Seodong Shin, Liang Yang +36
Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Ast…
Constraining Axion-Like Particles with HAWC Observations of TeV Blazars
Sunniva Jacobsen, Tim Linden, Katherine Freese
Axion-like particles (ALPs) are a broad class of pseudo-scalar bosons that generically arise from broken symmetries in extensions of the standard model. In many scenarios, ALPs can…
Response to Comment on "Dark Matter Annihilation Can Produce a Detectable Antihelium Flux through Decays"
Martin Wolfgang Winkler, Tim Linden
In a recent paper we showed that the decay of intermediate baryons can dramatically enhance the antihelium flux from dark matter annihilation. Our antihelium predictions…
Dark Matter Annihilation Can Produce a Detectable Antihelium Flux through Decays
Martin Wolfgang Winkler, Tim Linden
Recent observations by the Alpha Magnetic Spectrometer (AMS-02) have tentatively detected a handful of cosmic-ray antihelium events. Such events have long been considered as smokin…
Constraints on Spin-Dependent Dark Matter Scattering with Long-Lived Mediators from TeV Observations of the Sun with HAWC
A. Albert, R. Alfaro, C. Alvarez +91
We analyze the Sun as a source for the indirect detection of dark matter through a search for gamma rays from the solar disk. Capture of dark matter by elastic interactions with th…
Searching for Dark Matter with Neutron Star Mergers and Quiet Kilonovae
Joseph Bramante, Tim Linden, Yu-Dai Tsai
We identify new astrophysical signatures of dark matter that implodes neutron stars (NSs), which could decisively test whether NS-imploding dark matter is responsible for missing p…
