A Convolutional Neural Network Approach to Supernova Time-Series Classification
Helen Qu, Masao Sako, Anais Moller +1
One of the brightest objects in the universe, supernovae (SNe) are powerful explosions marking the end of a star's lifetime. Supernova (SN) type is defined by spectroscopic emissio…
What's the Difference? The potential for Convolutional Neural Networks for transient detection without template subtraction
Tatiana Acero-Cuellar, Federica Bianco, Gregory Dobler +3
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" cla…
The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
