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…
Super-Kamiokande Strongly Constrains Leptophilic Dark Matter Capture in the Sun
Thong T. Q. Nguyen, Tim Linden, Pierluca Carenza +1
The Sun can efficiently capture leptophilic dark matter that scatters with free electrons. If this dark matter subsequently annihilates into leptonic states, it can produce a detec…
