Cross-correlations between the CLAMATO Lyman-alpha forest and galaxies within the COSMOS field
Benjamin Zhang, Khee-Gan Lee, Andrei Cuceu +2
We compute the 3D cross-correlation between the absorption of the Lyman-alpha forest measured by the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) su…
Alignments Between Galaxies and the Cosmic Web at in the IllustrisTNG Simulations
Benjamin Zhang, Khee-Gan Lee, Alex Krolewski +3
Galaxy formation theories predict that galaxy shapes and angular momenta have non-random alignments with the cosmic web. This leads to so-called intrinsic alignment between pairs o…
Predicted future fate of COSMOS galaxy protoclusters over 11 Gyr with constrained simulations
Metin Ata, Khee-Gan Lee, Claudio Dalla Vecchia +5
Cosmological simulations are crucial tools in studying the Universe, but they typically do not directly match real observed structures. Constrained cosmological simulations, on the…
Constraining the Fluctuating Gunn-Peterson Approximation Using Lyman- Forest Tomography at
Robin Kooistra, Khee-Gan Lee, Benjamin Horowitz
The fluctuating Gunn-Peterson approximation (FGPA) is a commonly-used method to generate mock Lyman- (Ly) forest absorption skewers at Cosmic Noon () from the mat…
Second Data Release of the COSMOS Lyman-alpha Mapping and Tomographic Observation: The First 3D Maps of the Detailed Cosmic Web at 2.05<z<2.55
Benjamin Horowitz, Khee-Gan Lee, Metin Ata +12
We present the second data release of the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) Survey conducted with the LRIS spectrograph on the Keck-I telescope. This…
Constraining the Cosmic Baryon Distribution with Fast Radio Burst Foreground Mapping
Khee-Gan Lee, Metin Ata, Ilya S. Khrykin +5
The dispersion measures (DM) of fast radio bursts (FRBs) encode the integrated electron density along the line-of-sight, which is typically dominated by the intergalactic medium (I…
