The Dependence of Galaxy Properties on the Underlying 3D Matter Density Field at 2.0 < z < 2.5
Rieko Momose, Khee-Gan Lee, Benjamin Horowitz +2
We study the environmental effect of galaxy evolution as a function of the underlying 3D dark matter density for the first time at , in which the underlying matter density…
Plausible Adversarial Attacks on Direct Parameter Inference Models in Astrophysics
Benjamin Horowitz, Peter Melchior
In this abstract we explore the possibility of introducing biases in physical parameter inference models from adversarial-type attacks. In particular, we inject small amplitude sys…
Differentiable Stochastic Halo Occupation Distribution
Benjamin Horowitz, ChangHoon Hahn, Francois Lanusse +2
In this work, we demonstrate how differentiable stochastic sampling techniques developed in the context of deep Reinforcement Learning can be used to perform efficient parameter in…
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…
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…
