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…
Low-energy antinuclei measurements for background-free indirect dark matter searches and PBH signatures
Tsuguo Aramaki, Ilias Cholis, Philip von Doetinchem +7
Light low-energy cosmic ray antinuclei constitute powerful probes for detecting dark matter or other sources of new physics in our Galaxy. This ASTRA Initiative Mission Concept rev…
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…
A catalogue of TeV pulsar environments
Tina Wach, Tim Linden, Alison M. W. Mitchell +1
Pulsars and their environments represent a major class of Galactic gamma-ray sources. Their complex evolution, shaped by the interactions of the pulsar outflow with the supernova r…
On the Gamma-ray Efficiency of Superluminous Supernovae: Potential Detections and Population-Level Constraints
Milena Crnogorčević, Tim Linden, Ariel Goobar +1
Superluminous supernovae (SLSNe) are among the most energetic stellar explosions, yet their central power source remains uncertain. Models invoking magnetar spin-down or circumstel…
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…
Are X-Ray Detected Active Galactic Nuclei in Dwarf Galaxies Gamma-Ray Bright?
Milena Crnogorčević, Tim Linden, Annika H. G. Peter
The -ray emission from active galactic nuclei (AGN), including both beamed blazars and misaligned-AGN, dominates the extragalactic -ray point-source population count and flux…
The Impact of Muon and Pion Cooling on the Neutrino Spectrum of NGC 1068
Carlos Blanco, Dan Hooper, Tim Linden +1
The IceCube Neutrino Observatory has detected a flux of neutrinos from the active galaxy, NGC 1068. The soft spectral index of these neutrinos has previous…
Investigating the Gamma-Ray Emission from Explosive Dispersal Outflows with Fermi-LAT
Paarmita Pandey, Stephen C. Lenker, Laura A. Lopez +6
We present the first systematic study of explosive dispersal outflows (EDOs) as potential sources of high-energy emission in the Milky Way. EDOs are energetic outflows produced dur…
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…
First Observations of Solar Halo Gamma Rays Over a Full Solar Cycle
Tim Linden, Jung-Tsung Li, Bei Zhou +4
We analyze 15 years of Fermi-LAT data and produce a detailed model of the Sun's inverse-Compton scattering emission (solar halo), which is powered by interactions between ambient c…
Every Nearby Energetic Pulsar Is Surrounded by a Region of Inhibited Diffusion
Isabelle John, Tim Linden
The H.E.S.S. telescope has recently detected the total electron-plus-positron () flux up to 40 TeV, finding it to be a featureless and steeply-falling power-law above 1 TeV…
Looking for the γ-Ray Cascades of the KM3-230213A Neutrino Source
Milena Crnogorčević, Carlos Blanco, Tim Linden
The extreme energy of the KM3-230213A event could transform our understanding of the most energetic sources in the Universe. However, it also reveals an inconsistency between the K…
Heavy Axions Can Disrupt -ray Bursts
Oindrila Ghosh, Sunniva Jacobsen, Tim Linden
Axion-like particles (ALPs) can be produced in the hot dense plasma of fireballs that develop in the initial stage of -ray burst (GRB) outflows. They can transport an enormous a…
Gamma-Ray Observations of Galaxy Clusters Strongly Constrain Dark Matter Annihilation in Prompt Cusps
Milena Crnogorčević, M. Sten Delos, Nadia Kuritzén +1
Thermal dark matter models generically include the prompt creation of highly-concentrated dark matter cusps in the early Universe. Recent studies find that these cusps can survive…
