#BLACKHOLE PICTURE MEMORY SIZE SOFTWARE#
In this package, as illustrated by the partial software
NumPy is at the core of array data processing used Simulating and performing image reconstruction on VLBI data. Their work illustrates the role the scientific Python ecosystem plays inĪdvancing science through collaborative data analysis.įor example, the eht-imaging Python package provides tools for When results proved consistent, they were combined to yield the The EHT collaboration met these challenges by having independent teamsĮvaluate the data, using both established and cutting-edge image reconstruction What if there’s a problem with the data? Or perhaps an algorithm relies too When the goal is to see something never before seen, how can scientists beĮHT Data Processing Pipeline (Diagram Credits: The Astrophysical Journal, Event Horizon Telescope Collaboration) NumPy’s Role Reducing the volume and complexity of this much Widely dissimilar and geographically dispersed.Įach day EHT generates over 350 terabytes of observations, stored on Phase fluctuations, large recording bandwidth, and telescopes that are Use it to measure the black hole’s enormous mass.ĮHT poses massive data-processing challenges, including rapid atmospheric Gravitational bending and capture of light.
