TL;DR
SNIF is an online tool that allows users to interactively fit analytical models to supernova light curves powered by radioactive decay, magnetar spin-down, or ejecta-CSM interaction, leveraging extensive public data.
Contribution
It introduces an interactive web application that simplifies fitting diverse supernova models to observational data using a comprehensive catalog API.
Findings
Enables real-time fitting of supernova light curves
Supports multiple physical models for supernova brightness
Connects users to thousands of observed light curves
Abstract
We present an online application, the SuperNova Interactive Fitter (SNIF), which can be used to interactively fit one-zone, analytical models to optical transient light curves powered by (1) the radioactive decay of 56Ni, (2) the spin-down of newly born magnetars, or (3) the interaction between supernova ejecta and pre-existing circumstellar material. This application utilizes the Open Astronomy Catalogs API to connect the user to thousands of publicly available transient light curves from the literature.
