A measurement of the Hubble constant from Type II supernovae
T. de Jaeger, B. E. Stahl, W. Zheng +3
Progressive increases in the precision of the Hubble-constant measurement via Cepheid-calibrated Type Ia supernovae (SNe Ia) have shown a discrepancy of with the curren…
deepSIP: Linking Type Ia Supernova Spectra to Photometric Quantities with Deep Learning
Benjamin E. Stahl, Jorge Martinez-Palomera, WeiKang Zheng +3
We present {\tt deepSIP} (deep learning of Supernova Ia Parameters), a software package for measuring the phase and -- for the first time using deep learning -- the light-curve sha…
Berkeley Supernova Ia Program: Data Release of 637 Spectra from 247 Type Ia Supernovae
Benjamin E. Stahl, WeiKang Zheng, Thomas de Jaeger +18
We present 637 low-redshift optical spectra collected by the Berkeley Supernova Ia Program (BSNIP) between 2009 and 2018, almost entirely with the Kast double spectrograph on the S…
SN 2017cfd: A Normal Type Ia Supernova Discovered Very Young
Xuhui Han, WeiKang Zheng, Benjamin E. Stahl +22
The Type~Ia supernova (SN~Ia) 2017cfd in IC~0511 (redshift z = 0.01209+- 0.00016$) was discovered by the Lick Observatory Supernova Search 1.6+-0.7 d after the fitted first-light t…
The Berkeley sample of Type II supernovae: BVRI light curves and spectroscopy of 55 SNe II
T. de Jaeger, W. Zheng, B. E. Stahl +58
In this work, BV RI light curves of 55 Type II supernovae (SNe II) from the Lick Observatory Supernova Search program obtained with the Katzman Automatic Imaging Telescope and the…
Lick Observatory Supernova Search Follow-Up Program: Photometry Data Release of 93 Type Ia Supernovae
Benjamin E. Stahl, WeiKang Zheng, Thomas de Jaeger +52
We present BVRI and unfiltered light curves of 93 Type Ia supernovae (SNe Ia) from the Lick Observatory Supernova Search (LOSS) follow-up program conducted between 2005 and 2018. O…
