SALT3-UV: Improving Supernova Ia Models for UV Observations

Published:Dec 31, 2025 18:58
1 min read
ArXiv

Analysis

This paper addresses the challenge of standardizing Type Ia supernovae (SNe Ia) in the ultraviolet (UV) for upcoming cosmological surveys. It introduces a new optical-UV spectral energy distribution (SED) model, SALT3-UV, trained with improved data, including precise HST UV spectra. The study highlights the importance of accurate UV modeling for cosmological analyses, particularly concerning potential redshift evolution that could bias measurements of the equation of state parameter, w. The work is significant because it improves the accuracy of SN Ia models in the UV, which is crucial for future surveys like LSST and Roman. The paper also identifies potential systematic errors related to redshift evolution, providing valuable insights for future cosmological studies.

DFINE for Nonlinear Modeling of Human iEEG Activity

Published:Dec 28, 2025 05:05
1 min read
ArXiv

Analysis

This paper introduces an extension of the DFINE framework for modeling human intracranial electroencephalography (iEEG) recordings. It addresses the limitations of linear dynamical models in capturing the nonlinear structure of neural activity and the inference challenges of recurrent neural networks when dealing with missing data, a common issue in brain-computer interfaces (BCIs). The study demonstrates that DFINE outperforms linear state-space models in forecasting future neural activity and matches or exceeds the accuracy of a GRU model, while also handling missing observations more robustly. This work is significant because it provides a flexible and accurate framework for modeling iEEG dynamics, with potential applications in next-generation BCIs.
