Collapsars as Sites of r-process Nucleosynthesis: Systematic Near-Infrared Follow-up of Type Ic-BL Supernovae
Shreya Anand, Jennifer Barnes, Sheng Yang +41
One of the open questions following the discovery of GW170817 is whether neutron star mergers are the only astrophysical sites capable of producing -process elements. Simulation…
HAFFET: Hybrid Analytic Flux FittEr for Transients
Sheng Yang, Jesper Sollerman
The progenitors for many types of supernovae (SNe) are still unknown, and an approach to diagnose their physical origins is to investigate the light curve brightness and shape of a…
SN 2018bsz: significant dust formation in a nearby superluminous supernova
T. -W. Chen, S. J. Brennan, R. Wesson +41
We investigate the thermal emission and the extinction from dust associated with the nearby (z = 0.0267) superluminous supernova (SLSN) 2018bsz. Our dataset combines daily-cadence,…
Magnetar-Driven Shock Breakout Revisited and Implications for Double-Peaked Type I Superluminous Supernovae
Liang-Duan Liu, He Gao, Xiao-Feng Wang +1
The discovery of early bumps in some type-I superluminous supernovae (SLSNe-I) before the main peaks offers an important clue to their energy source mechanisms. In this paper, we u…
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…
Gravitational wave optical counterpart searching based on GRAWITA and DLT40 project during LIGO O2 run
Sheng Yang
The identification of the electromagnetic(EM) counterpart of gravitational wave(GW) trigger in the sky localization is a very difficult task because of the large uncertainty. Two c…
The discovery of the electromagnetic counterpart of GW170817: kilonova AT 2017gfo/DLT17ck
Stefano Valenti, David J. Sand, Sheng Yang +7
During the second observing run of the Laser Interferometer gravitational- wave Observatory (LIGO) and Virgo Interferometer, a gravitational-wave signal consistent with a binary ne…
An empirical limit on the kilonova rate from the DLT40 one day cadence Supernova Survey
Sheng Yang, Stefano Valenti, Enrico Cappellaro +6
Binary neutron star mergers are important to understand stellar evolution, the chemical enrichment of the universe via the r-process, the physics of short gamma-ray bursts, gravita…
