Photometric and Spectroscopic Observations of GRB 140629A
2018
Astrophysical Journal
We present our optical photometric and spectroscopical observations of GRB 140629A. A redshift of z=2.275±0.043 is measured through the metal absorption lines in our spectroscopic data. Using our photometric data and multiple observational data observed with other telescopes, we show that its optical light curve is well interpreted with the standard forward shock models in the thin shell case. Its optical-X-ray afterglow spectrum is jointly fitted with a single power-law function, yielding a
