Deep Drilling in the Time Domain with DECam: Survey Characterization
Melissa L. Graham, Robert A. Knop, Thomas Kennedy +41
This paper presents a new optical imaging survey of four deep drilling fields (DDFs), two Galactic and two extragalactic, with the Dark Energy Camera (DECam) on the 4 meter Blanco…
Artificial Intelligence Assisted Inversion (AIAI): Quantifying the Spectral Features of Ni of Type Ia Supernovae
Xingzhuo Chen, Lifan Wang, Lei Hu +1
Following our previous study of Artificial Intelligence Assisted Inversion (AIAI) of supernova analyses (Chen et al. 2020), we train a set of deep neural networks based on the one-…
The Interaction of Supernova 2018evt with a Substantial Amount of Circumstellar Matter -- An SN1997cy-like Event
Yi Yang, Dietrich Baade, Peter Hoeflich +29
A rare class of supernovae (SNe) is characterized by strong interaction between the ejecta and several solar masses of circumstellar matter (CSM) as evidenced by strong Balmer-line…
Using 1991T/1999aa-like Type Ia Supernovae as Standardizable Candles
Jiawen Yang, Lifan Wang, Nicholas Suntzeff +13
We present the photometry of 16 91T/99aa-like Type Ia Supernovae (SNe Ia) observed by the Las Cumbres Observatory. We also use an additional set of 21 91T/99aa-like SNe Ia and 87 n…
Pipeline for Antarctic Survey Telescope 3-3 in Yaoan, Yunnan
Tianrui Sun, Lei Hu, Songbo Zhang +5
AST3-3 is the third robotic facility of the Antarctic Survey Telescopes (AST3) for transient surveys to be deployed at Dome A, Antarctica. Due to the current pandemic, the telescop…
Spectroscopic Studies of Type Ia Supernovae Using LSTM Neural Networks
Lei Hu, Xingzhuo Chen, Lifan Wang
We present a data-driven method based on long short-term memory (LSTM) neural networks to analyze spectral time series of Type Ia supernovae (SNe Ia). The dataset includes 3091 spe…
