The Lumina Project: Intergalactic Clumping and Recombination Sinks

Ali Sadain, Aaron Smith, Oliver Zier +10

Recombinations during the Epoch of Reionization are intrinsically inhomogeneous, with different regions of the intergalactic medium contributing unevenly depending on their density…

Double-Peaked Ly Emission during Reionization Requires Nearby Voids and a Favorable Local Ionizing Background

Hyunbae Park, Aaron Smith, Intae Jung +11

Several Lyman-alpha (Ly) emitters deep into the reionization era exhibit double-peaked Ly emission profiles, raising the question of how the intergalactic medium can transmit…

The Thermal Sunyaev-Zel'dovich Effect from the Epoch of Reionization

Ilian T. Iliev, Azizah R. Hosein, Jens Chluba +11

The thermal Sunyaev-Zel'dovich (tSZ) effect arises from inverse Compton scattering of low energy photons onto thermal electrons, proportional to the integrated electron pressure, a…

The Impact of baryonic physics on the kinetic Sunyaev-Zel'dovich Effect

Hyunbae Park, Marcelo A. Alvarez, J. Richard Bond

Poorly understood "baryonic physics" impacts our ability to predict the power spectrum of the kinetic Sunyaev-Zel'dovich (kSZ) effect. We study this in one sample high resolution s…
