Discovery of Magnetic Fields Along Stacked Cosmic Filaments as Revealed by Radio and X-Ray Emission
Tessa Vernstrom, George Heald, Franco Vazza +5
Diffuse filaments connect galaxy clusters to form the cosmic web. Detecting these filaments could yield information on the magnetic field strength, cosmic ray population and temper…

Dark Matter searches through cross-correlations of gamma rays with neutral-hydrogen intensity mapping
Elena Pinetti
In this work we derive the first theoretical prediction of the cross-correlation signal between the unresolved gamma-ray background and the 21-cm line originated by the spin-flip t…

Synergies across the spectrum for particle dark matter indirect detection: how HI intensity mapping meets gamma rays
Elena Pinetti, Stefano Camera, Nicolao Fornengo +1
Neutral hydrogen (HI) intensity mapping traces the large-scale distribution of matter in the Universe and therefore should correlate with the gamma-ray emission originated from par…
