TRINITY IV: Predictions for Supermassive Black Holes at
Haowen Zhang, Peter Behroozi, Marta Volonteri +6
We present predictions for the high-redshift halo-galaxy-supermassive black hole (SMBH) connection from the TRINITY model. Constrained by a comprehensive compilation of galaxy ($0\…
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…
The Impact of Star Formation and Gamma-Ray Burst Rates at High Redshift on Cosmic Chemical Evolution and Reionization
E. Vangioni, K. A. Olive, T. Prestegard +3
Recent observations in the total luminosity density have led to significant progress in establishing the star formation rate (SFR) at high redshift. Concurrently observed gamma-ray…
Simulating SZ intensity maps of giant AGN cocoons
D. A. Prokhorov, A. Moraghan, V. Antonuccio-Delogu +1
We perform relativistic hydrodynamic simulations of the formation and evolution of AGN cocoons produced by very light powerful jets. We calculate the intensity maps of the Sunyaev-…
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…
Comptonization of the cosmic microwave background by high energy particles residing in AGN cocoons
D. A. Prokhorov, V. Antonuccio-Delogu, J. Silk
X-ray cavities and extended radio sources (`cocoons') surrounding active galactic nuclei (AGN) have been detected by the Chandra X-ray mission and radio interferometers. A joint an…
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…
Influence of Population III stars on cosmic chemical evolution
E. Rollinde, E. Vangioni, D. Maurin +4
New observations from the Hubble ultra deep field suggest that the star formation rate at z>7 drops off faster than previously thought. Using a newly determined star formation rate…
On the Origin of Stars in Bulges and Elliptical Galaxies
S. Khochfar, J. Silk
We investigate the stellar composition of bulges and elliptical galaxies as predicted by the CDM paradigm using semi-analytical modelling. We argue that spheroid stars are built up…
How old is the Universe ? Setting new constraints on the age of the Universe
I. Ferreras, A. Melchiorri, J. Silk
There are three independent techniques for determining the age of the universe: via cosmochronology of long-lived radioactive nuclei, via stellar modelling and population synthesis…
Cosmological History of Stars and Metals
R. Sadat, B. Guiderdoni, J Silk
We study the evolution of stellar content and the chemical enrichment of the universe averaged over the whole population of galaxies by means of a series of chemo-spectrophotometri…
Extracting Primordial Density Fluctuations
Eric Gawiser, Joseph Silk
The combination of detections of anisotropy in the Cosmic Microwave Background radiation and observations of the large-scale distribution of galaxies probes the primordial density…
Evolution of Galaxies in Clusters
S. Charlot, J. Silk
We use new models of stellar population synthesis to estimate the fraction of stars formed during the last major bursts of star formation in E/S0 galaxies in low-redshift clusters…
