Stellar-like Galactic center excess challenges particle dark matter
Silvia Manconi, Christopher Eckner, Francesca Calore +1
The authors re‑analyse Fermi‑LAT gamma‑ray data from the Galactic Center using adaptive template fitting and photon‑count statistics to separate a possible dark‑matter signal from…
Probing the Parameter Space of Axion-Like Particles Using Simulation-Based Inference
Pooja Bhattacharjee, Christopher Eckner, Gabrijela Zaharijas +2
Axion-like particles (ALPs), hypothetical pseudoscalar particles that couple to photons, are among the most actively investigated candidates for new physics beyond the Standard Mod…
Prospects on detection of the Fermi Bubbles with CTAO
Francesco Xotta, Nina Bavdaž, Christopher Eckner +3
In 2010, the Fermi Gamma-ray Space Telescope observed two gamma-ray emitting structures, the Fermi Bubbles (FBs), that extend up to 55° above and below the Galactic plane and that…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
Lecture Notes: WISPs in gamma-ray astrophysics
Francesca Calore, Christopher Eckner
These lecture notes provide an overview of high-energy astrophysical processes involving axions, axion-like particles (ALPs), and other weakly interacting slim particles (WISPs) fo…
