I'm Seán, an astronomer at the Oskar Klein Centre, Stockholm University, Sweden, researching mass loss from massive stars, and interacting transients.
My current work is focused on searching for pre-supernova, progenitor activity to better understand what a massive star does in its final weeks to months before core-collapse.
Open-source code increases transparency, allows for review and validation, and improves reproducibility. - if code shown in my work can aid in your science case, contact me at sean.brennan@astro.su.se.
