Constraining the redshifted 21-cm signal with the unresolved soft X-ray background
Anastasia Fialkov, Aviad Cohen, Rennan Barkana +1
We use the observed unresolved cosmic X-ray background (CXRB) in the 0.5-2 keV band and existing upper limits on the 21-cm power spectrum to constrain the high-redshift population…
Locally Cold Flows from Large-Scale Structure
M. A. Aragon-Calvo, J. Silk, A. S. Szalay
We show that the "cold" Hubble flow observed for galaxies around the Milky Way does not represent a problem in cosmology but is due to the particular geometry and dynamics of our l…
Cosmic Chemical Evolution with an Early Population of Intermediate Mass Stars
Elisabeth Vangioni, Joseph Silk, Keith A. Olive +1
We explore the consequences of an early population of intermediate mass stars in the 2 - 8 M\odot range on cosmic chemical evolution. We discuss the implications of this population…
A redshift survey towards the CMB Cold Spot
M. N. Bremer, J. Silk, L. J. M. Davies +1
We have carried out a redshift survey using the VIMOS spectrograph on the VLT towards the Cosmic Microwave Background cold spot. A possible cause of the cold spot is the Integrated…
AGN activity: Self-regulation from backflow
V. Antonuccio-Delogu, J. Silk
We study the internal circulation within the cocoon carved out by the relativistic jet emanating from an AGN within the ISM of its host galaxy. Firstly, we develop a model for the…
