Bounds on dark matter annihilations from 21cm data

The observation of an absorption feature in the 21 cm spectrum at redshift z ≈17 implies bounds on Dark Matter annihilations for a broad range of masses,given that significant heating of the intergalactic medium would have erasedsuch feature. The resulting bounds on the DM annihilation cross section...

description The observation of an absorption feature in the 21 cm spectrum at redshift z ≈17 implies bounds on Dark Matter annihilations for a broad range of masses,given that significant heating of the intergalactic medium would have erasedsuch feature. The resulting bounds on the DM annihilation cross sections arecomparable to the strongest ones from all other observables.
