The Redshift of GRB 190829A/SN 2019oyw: A Case Study of GRB-SN Evolution

The Redshift of GRB 190829A/SN 2019oyw: A Case Study of GRB-SN Evolution

The nearby long gamma-ray burst (GRB) 190829A was observed using the Hubble Space Telescope/Wide Field Camera 3/infrared grisms about four weeks to 500 days after the burst. We find the spectral features of its associated supernova, SN 2019oyw, are redshifted by several thousand km s ^−1 compared to...
