Photo-zSNthesis: Converting Type Ia Supernova Lightcurves to Redshift Estimates via Deep Learning

no code implementations19 May 2023 Helen Qu, Masao Sako

Upcoming photometric surveys will discover tens of thousands of Type Ia supernovae (SNe Ia), vastly outpacing the capacity of our spectroscopic resources.

A Convolutional Neural Network Approach to Supernova Time-Series Classification

no code implementations19 Jul 2022 Helen Qu, Masao Sako, Anais Moller, Cyrille Doux

Retrospective classification is used to differentiate cosmologically useful Type Ia SNe from other SN types, and this method achieves >99% accuracy on this task.

What's the Difference? The potential for Convolutional Neural Networks for transient detection without template subtraction

1 code implementation14 Mar 2022 Tatiana Acero-Cuellar, Federica Bianco, Gregory Dobler, Masao Sako, Helen Qu, The LSST Dark Energy Science Collaboration

We present a study of the potential for Convolutional Neural Networks (CNNs) to enable separation of astrophysical transients from image artifacts, a task known as "real-bogus" classification without requiring a template subtracted (or difference) image which requires a computationally expensive process to generate, involving image matching on small spatial scales in large volumes of data.
