A Snapshot Survey of Nearby Supernovae with the Hubble Space Telescope
Raphael Baer-Way, Asia DeGraw, Weikang Zheng +12
Over recent decades, robotic (or highly automated) searches for supernovae (SNe) have discovered several thousand events, many of them in quite nearby galaxies (distances < 30 Mpc)…
Record-breaking polarization from the interacting superluminous supernova 2017hcc
Jon C. Mauerhan, Nathan Smith, G. Grant Williams +12
We present multiepoch spectropolarimetry of the superluminous interacting Type IIn supernova SN2017hcc, covering 16 to 391 days after explosion. In our first epoch we measure conti…
What Does the Virial Coefficient of the \Hb Broad-Line Region Depend On?
Lizvette Villafaña, Peter R. Williams, Tommaso Treu +37
We combine our dynamical modeling black hole mass measurements from the Lick AGN Monitoring Project 2016 sample with measured cross-correlation time lags and line widths to recover…
The Lick AGN Monitoring Project 2016: Dynamical Modeling of Velocity-Resolved H\b{eta} Lags in Luminous Seyfert Galaxies
Lizvette Villafaña, Peter R. Williams, Tommaso Treu +62
We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring…
The Lick Observatory Supernova Search follow-up program: photometry data release of 70 stripped-envelope supernovae
WeiKang Zheng, Benjamin E. Stahl, Thomas de Jaeger +85
We present BVRI and unfiltered Clear light curves of 70 stripped-envelope supernovae (SESNe), observed between 2003 and 2020, from the Lick Observatory Supernova Search (LOSS) foll…
The Lick AGN Monitoring Project 2016: Velocity-Resolved Hβ Lags in Luminous Seyfert Galaxies
Vivian U, Aaron J. Barth, H. Alexander Vogler +61
We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3-m Shane telescope at Lick Observatory from April 2016 to M…
SN 2017fgc: A Fast-Expanding Type Ia Supernova Exploded in Massive Shell Galaxy NGC 474
Xiangyun Zeng, Xiaofeng Wang, Ali Esamdin +31
We present extensive optical photometric and spectroscopic observations of the high-velocity (HV) Type Ia supernova (SN Ia) 2017fgc, covering the phase from 12 d before to $…
Progenitor mass constraints for the type Ib intermediate-luminosity SN 2015ap and the highly extinguished SN 2016bau
Amar Aryan, S. B. Pandey, WeiKang Zheng +21
Photometric and spectroscopic analyses of the intermediate-luminosity Type Ib supernova (SN) 2015ap and of the heavily reddened Type Ib SN~2016bau are discussed. Photometric proper…
SN 2017hpa: A Nearby Carbon-Rich Type Ia Supernova with a Large Velocity Gradient
Xiangyun Zeng, Xiaofeng Wang, Ali Esamdin +24
We present extensive, well-sampled optical and ultraviolet photometry and optical spectra of the Type Ia supernova (SN Ia) 2017hpa. The light curves indicate that SN 2017hpa is a n…
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…
