+    "long_description": "We are delighted to announce that our NSF research proposal (led by Maryam Modjaz, Wolfgang Kerzendorf with large contributions by Marc Williamson) on the study of massive stars and their explosive deaths, known as Stripped Supernovae, has successfully secured funding. With access to the largest dataset of Stripped Supernovae in existence, our team aims to unravel the complexities surrounding these cataclysmic events. By analyzing the optical spectra and light curves of three dozen Stripped Supernovae, along with employing the open-source radiative transfer code TARDIS and machine learning technology, we will gain unprecedented insights into the progenitor make-up and explosion dynamics of these cosmic phenomena. This research has far-reaching implications, not only for understanding stellar evolution, but also for exploring the conditions required for jet production and clarifying the contentious SN-GRB progenitor models. By shedding light on these fundamental aspects, we will pave the way for utilizing Stripped Supernovae as indicators of star formation across vast cosmic distances and investigating their role in re-ionizing the Universe. Furthermore, our findings will help advance the field of time-domain astronomy, as our modeling framework can be adapted to analyze other types of supernovae and astrophysical events, such as Superluminous SNe Ic and kilonova spectra. This project will enable us to address critical questions, resolve long-standing controversies, and contribute to a deeper understanding of the cosmos.",

+    "long_description": "The community agrees that Type Ia supernovae arise from Carbon/Oxygen white dwarfs undergoing thermonuclear runaway. However, the full progenitor system and the process that prompts the white dwarf to explode remain unknown. Most current models suggest that the white dwarf explodes because of interaction with a binary companion which may survive the process and remain within the resulting remnant of the exploded star. Furthermore, both the pre-supernova interaction process and the explosion of the primary are expected to imprint a significant departure from ordinary stellar radii and temperatures onto the secondary, making the star identifiable against the unrelated stellar population. Identification of a surviving companion inside an SN Ia remnant might confirm a specific corresponding SN Ia progenitor channel based on the identity of the companion. We conducted a surviving companion search of the Type Ia remnant SNR 0509−67.5based in the Large Magellanic Cloud. The well-constrained distance to and foreground extinction of the Large Magellanic Cloud allow for Bayesian inference of stellar parameters with low correlation and uncertainties. We present a deep catalog of fully characterized stars interior to SNR 0509−67.5 with radii, effective temperatures, and metallicities inferred using combined Hubble Space Telescope photometric observations across multiple visits. We then compile a list of surviving companion models appropriate for the age of the remnant (roughly 400 years after the explosion). We compare these predictions with the inferred stellar parameters and conclude that none of the stars are consistent with the predicted signatures of a surviving companion.",

The transmission curve of each filters is shown in dashed purple.
