The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars

LAT Collaboration

The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…

Simulating Cosmic Reionization and the Radiation Backgrounds from the Epoch of Reionization

Paul R. Shapiro, Ilian T. Iliev, Garrelt Mellema +10

Large-scale reionization simulations are described which combine the results of cosmological N-body simulations that model the evolving density and velocity fields and identify the…

Will Nonlinear Peculiar Velocity and Inhomogeneous Reionization Spoil 21cm Cosmology from the Epoch of Reionization?

Paul R. Shapiro, Yi Mao, Ilian T. Iliev +4

The 21cm background from the epoch of reionization is a promising cosmological probe: line-of-sight velocity fluctuations distort redshift, so brightness fluctuations in Fourier sp…

Gravitationally Lensed Galaxies at 2<z<3.5: Direct Abundance Measurements of Lya Emitters

Lise Christensen, Peter Laursen, Johan Richard +6

Strong gravitational lensing magnifies the flux from distant galaxies, allowing us to detect emission lines that would otherwise fall below the detection threshold for medium-resol…

The Low Mass End of the Fundamental Relation for Gravitationally Lensed Star Forming Galaxies at 1<z<6

Lise Christensen, Johan Richard, Jens Hjorth +6

We present VLT/X-shooter spectra of 13 galaxies in the redshift range 1< z < 6, which are strongly lensed by massive galaxy clusters. Spectroscopic redshifts are measured for nine…

Magnetic Fields from QCD Phase Transitions

Alexander G. Tevzadze, Leonard Kisslinger, Axel Brandenburg +1

We study the evolution of QCD phase transition-generated magnetic fields in freely decaying MHD turbulence of the expanding Universe. We consider a magnetic field generation model…
