We show that powerful quasars feed enough energy back to the diffuse ambient baryons as to cause transient, enhanced Sunyaev-Zel’dovich effects, especially in early galaxies and groups. We compute amplitudes and statistics of the related signals in μwave and submm bands, and discuss their detectability with present and future instruments.

Abstract
We show that powerful quasars feed enough energy back to the diffuse ambient baryons as to cause transient, enhanced Sunyaev-Zel’dovich effects, especially in early galaxies and groups. We compute amplitudes and statistics of the related signals in μwave and submm bands, and discuss their detectability with present and future instruments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
