About

I build the software that gets a telescope onto a gamma-ray burst while it is still bright, and photograph the Tasmanian coast in infrared and on film.

I'm Harrison Harper. I graduated from the University of Tasmania with First Class Honours in Physics and work as a photographer and software developer. My research is in time-domain astronomy: automated FITS reduction and photometry pipelines, and the real-time alert infrastructure that gets a telescope onto a gamma-ray burst while it is still bright.

That work includes the pipeline behind the University of Tasmania's first confirmed gamma-ray burst detection, a Kafka-based GCN alert network spanning nine instrument topics, and multi-epoch photometry of the interstellar comet 3I/ATLAS. Away from the data, I shoot infrared and film photography around Hobart and the Tasmanian coast, and build interactive things for the web.

Pipelines, alerts and software.

All research / projects
  1. 01 GRB Detection Pipeline python · fits · astropy · astronomy Automated FITS reduction pipeline for calibration, source extraction, astrometry and time-based stacking. It produced the University of Tasmania's first confirmed gamma-ray burst detection, which is being prepared for publication. Research 2025 In progress
  2. 02 GCN Alert Network python · kafka · SQL · astronomy Persistent Kafka consumer across nine instrument topics that normalises GRB alert formats into a single internal schema. Routes observatory-filtered notifications to observing teams in near real-time. Research 2025
  3. 03 3I/ATLAS Photometry python · astropy · photometry · astronomy Multi-epoch light curve pipeline for interstellar comet 3I/ATLAS. Ephemeris queries from NASA JPL Horizons automate aperture placement on the moving target; nightly zero-points are derived from PanSTARRS and SkyMapper catalogues to account for varying conditions across sessions. Research 2025–2026
  4. 04 Exoplanet Transit Analysis: GJ 1132b python · batman · hubble · spitzer Joint transit model fitted to Hubble and Spitzer datasets. Each instrument processed with its own calibration routines before normalisation; Batman extracted the transit depth and physical parameters of the planet from the combined light curve. Research 2024
  5. 05 Stowpad Swift · OCR · Apple Intelligence · privacy Private clipboard manager for Mac that keeps an encrypted, searchable history of everything you copy. It uses on-device OCR to capture text and tables from the screen, then lets you paste any clip back into any app. Software 2026
  6. 06 React & Motion Dashboard react · motion · typescript · web design A dashboard of animations and interactive effects built in React and Motion. Magnetic cursors, physics springs, gesture-driven components, and other UI experiments collected in one place. Software 2024
