Undergraduate Research Fellow at the Berger Cosmic Transients Lab
-
May 2020 - Sep 2022
Worked with Dr. Griffin Hosseinzadeh and Dr. V. Ashley Villar under the supervision of Prof. Edo Berger to analyze, for the first time, hydrogen-poor superluminous supernovae from the Pan-STARRS1 Medium-Deep Survey classified by two independent machine learning based algorithms, Superphot and SuperRAENN. Streamlined a simple set of selection criteria that effectively cull the photometric sample, which enabled robust modeling with a magnetar central engine using the Modular Open-Source Fitter for Transient. Results point to the low-luminosity nature of the photometric sample that is often overlooked in optical surveys. Such analysis based on photometric classification will be essential in the era of LSST, which does not have the capacity for large-scale spectroscopic observations.This project is partially funded by the Harvard College Research Program (Summer 2020).

Sep 2020 - Nov 2021
Worked with Dr. Griffin Hosseinzadeh under the supervision of Prof. Edo Berger to model a sample of hydrogen-poor superluminous supernovae (SLSNe) from the Dark Energy Survey with a magnetar spin-down central engine. Generated synthetic multi-color light curves using the Modular Open-Source Fitter for Transients (MOSFiT) on the FASRC Cannon cluster at Harvard University. Comparison to literature sample using statistical analyses indicated no discernible redshift evolution in magnetar model parameters and confirmed previously found negative correlation between ejecta mass and magnetar spin period. A larger sample of SLSNe with higher redshift origin from future surveys such as LSST are required to further investigate the potential in redshift evolution.Article published in the Astrophysical Journal (ApJ).
