Prompt cusps in hierarchical dark matter halos: Implications for annihilation boost
Shin'ichiro Ando, MartÃn Moró González, Youyou Li
The paper investigates how compact "prompt cusps" that survive hierarchical merging in dark matter halos can enhance the expected dark matter annihilation signal, using a semi‑anal…

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…

Multi-messenger modeling of the Monogem pulsar halo
Youyou Li, Oscar Macias, Shinichiro Ando +1
The High-Altitude Water Cherenkov Telescope (HAWC) has detected TeV halos associated with two nearby pulsars/pulsar wind nebulae (PWN) -- Geminga and B0656+14. These TeV halos exte…
