EDGES Analysis Pipeline

I am the primary developer of a new software pipeline for EDGES data. This involves a stack of codes for data reading/writing, calibration, analysis and parameter estimation.

The software is developed by a small team, and I am overseeing the development, in order to transform the EDGES analysis pipeline into something that is highly transparent, reproducible and accurate.

hera-sim

hera_sim is one of the primary codes I contribute to in the HERA software suite. It is geared at simulating HERA-specific instrumental effects (thermal noise, cross-coupling, cable reflections) and injecting them into simulated visibilities.

This code is central to validating HERA’s analysis pipeline (as discussed in the linked paper).

matvis
matvis is a visibility simulator: it computes what an interferometer (like HERA) would measure given a model of the sky. This process is incredibly computationally demanding for telescopes like HERA that have several hundred antennas (and, more importantly, several tens of thousands of pairs of antennas). matvis adopts a novel matrix-based approach to the computation that gets significant acceleration from modern GPUs. The original author of this code was Aaron Parsons. I have been the primary maintainer and performance-enhancer in recent times.
