Connecting Reionization to the Local Universe
Marcelo A. Alvarez, Michael T. Busha, Tom Abel +1
We present results of combined N-body and three-dimensional reionization calculations to determine the relationship between reionization history and local environment in a volume 1…
Accretion onto the First Stellar Mass Black Holes
Marcelo A. Alvarez, John H. Wise, Tom Abel
The first stars in the universe, forming at redshifts z>15 in minihalos with masses of order 10^6 Msun, may leave behind black holes as their remnants. These objects could conceiva…
The contribution of star formation and merging to stellar mass buildup in galaxies
Niv Drory, Marcelo Alvarez
We present a formalism to infer the presence of merging by comparing the time derivative of the observed galaxy stellar mass function (MF) to the change of the MF expected from the…
Quasar H II Regions During Cosmic Reionization
Marcelo A. Alvarez, Tom Abel
Cosmic reionization progresses as HII regions form around sources of ionizing radiation. Their average size grows continuously until they percolate and complete reionization. We de…
The Signature of Patchy Reionization in the Polarization Anisotropy of the CMB
Olivier Doré, Gil Holder, Marcelo Alvarez +4
The inhomogeneous ionization state of the universe when the first sources of ionizing radiation appeared should lead to anisotropies in the polarization of the cosmic microwave bac…
Recognizing the First Radiation Sources Through Their 21-cm Signature
Leonid Chuzhoy, Marcelo A. Alvarez, Paul R. Shapiro
At the beginning of the reionization epoch, radiation sources produce fluctuations in the redshifted 21-cm background. We show that different types of sources (such as miniquasars,…
