OpenUniverse2024: a shared, simulated view of the sky for the next generation of cosmological surveys Open

A. Alarcon, Lauren Aldoroty, Gillian D. Beltz-Mohrmann, Apurba Bera, J Blazek , et al. · 2025

The OpenUniverse2024 simulation suite is a cross-collaboration effort to produce matched simulated imaging for multiple surveys as they would observe a common simulated sky. Both the simulated data and associated tools used to produce it a…

Introducing STARDIS: An Open and Modular Stellar Spectral Synthesis Code Open

J. Shields, Wolfgang Kerzendorf, Isaac G. Smith, Tiago M. D. Pereira, C. Vogl , et al. · 2025

We introduce a new 1D stellar spectral synthesis Python code called stardis . stardis is a modular, open-source radiative transfer code that is capable of spectral synthesis from near-UV to IR for FGK stars. We describe the structure, inpu…

1991T-Like Type Ia Supernovae as an Extension of the Normal Population Open

Jack O’Brien, Wolfgang Kerzendorf, Andrew G. Fullard, Rüdiger Pakmor, Johannes Büchner , et al. · 2024

Type Ia supernovae (SNe) remain poorly understood despite decades of investigation. Massive computationally intensive hydrodynamic simulations have been developed and run to model an ever-growing number of proposed progenitor channels. Fur…

Over 500 Days in the Life of the Photosphere of the Type Iax Supernova SN 2014dt Open

Yssavo Camacho-Neves, Saurabh W. Jha, Barnabás Barna, Mi Dai, A. V. Filippenko , et al. · 2023

Type Iax supernovae (SNe Iax) are the largest known class of peculiar white dwarf SNe, distinct from normal Type Ia supernovae (SNe Ia). The unique properties of SNe Iax, especially their strong photospheric lines out to extremely late tim…

SN 2019ewu: A Peculiar Supernova with Early Strong Carbon and Weak Oxygen Features from a New Sample of Young SN Ic Spectra Open

Marc Williamson, C. Vogl, M. Modjaz, Wolfgang Kerzendorf, Jaladh Singhal , et al. · 2023

With the advent of high-cadence, all-sky automated surveys, supernovae (SNe) are now discovered closer than ever to their dates of explosion. However, young premaximum light follow-up spectra of Type Ic SNe (SNe Ic), probably arising from …
