Discovery and Rapid Follow-up Observations of the Unusual Type II SN 2018ivc in NGC 1068
K. A. Bostroem, S. Valenti, D. J. Sand +44
We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual Type II supernova that exploded in NGC 1068 (D=10.1 Mpc). The light curve of SN 2018ivc d…
Searches After Gravitational-waves Using ARizona Observatories (SAGUARO): System Overview and First Results from Advanced LIGO/Virgo's Third Observing Run
M. J. Lundquist, K. Paterson, W. Fong +53
We present Searches After Gravitational-waves Using ARizona Observatories (SAGUARO), a comprehensive effort dedicated to the discovery and characterization of optical counterparts…
SN 2017gmr: An energetic Type II-P supernova with asymmetries
Jennifer E. Andrews, D. J. Sand, S. Valenti +77
We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the first 180 days…
Nebular H Limits for Fast Declining Type Ia Supernovae
D. J. Sand, R. C. Amaro, M. Moe +16
One clear observational prediction of the single degenerate progenitor scenario as the origin of type Ia supernovae (SNe) is the presence of relatively narrow (1000 km s$^…
Signatures of Circumstellar Interaction in the Type IIL Supernova ASASSN-15oz
K. Azalee Bostroem, Stefano Valenti, Assaf Horesh +27
Hydrogen-rich, core-collapse supernovae are typically divided into four classes: IIP, IIL, IIn, and IIb. In general, interaction with circumstellar material is only considered for…
Optical follow-up of gravitational wave events during the second advanced LIGO/VIRGO observing run with the DLT40 Survey
Sheng Yang, David J. Sand, Stefano Valenti +7
We describe the GW follow-up strategy and subsequent results of the DLT40 during the second science run (O2) of the LVC. Depending on the information provided in the GW alert toget…
