Constraints on Annihilating Dark Matter from Gamma-Ray Background-Galaxy Shape Correlations: Model-independent Null Results and Moderate Template-based Signals
Masato Shirasaki, Deheng Song, Oscar Macias +2
The paper uses cross‑correlations between the unresolved gamma‑ray background measured by Fermi‑LAT and galaxy shape data from DES Y3 and DECADE to place limits on dark‑matter anni…

Geminga and Monogem in the CTAO Era: Probing TeV Halos and Cosmic-Ray Transport
Youyou Li, Oscar Macias, Manuela Vecchi +1
TeV halos around Geminga and Monogem (B0656+14) reveal regions of strongly suppressed diffusion near middle-aged pulsars. Determining the sizes and magnetic-field strengths of thes…
