Novel bounds on decaying axionlike particle dark matter from the cosmic background

Horns, Dieter; Porras-Bedmar, Sara; Meyer, Manuel

The cosmic background (CB) is defined as the isotropic diffuse radiation field with extragalactic origin found across the electromagnetic spectrum. Different astrophysical sources dominate the CB emission at different energies, such as stars in the optical or active galactic nuclei in x rays. Assuming that dark matter consists of axions or axionli…
