Malesani, D., Tagliaferri, G., Chincarini, G., Covino, S., Della Valle, M., Fugazza, D., ...
Optical and near-infrared observations of the gamma-ray burst GRB 031203, at z = 0.1055, are reported. A very faint afterglow is detected superimposed to the host galaxy in our first infrared JHK...
SN 2002lt and GRB 021211: a SN/GRB Connection at z = 1 (2003)
Della Valle, M., Malesani, D., Benetti, S., Testa, V., Hamuy, M., Antonelli, L. A., ...
We present spectroscopic and photometric observations of the afterglow of GRB 021211 and the discovery of its associated supernova, SN 2002lt. The spectrum shows a broad feature (FWHM = 150 A),...
Della Valle, M., Malesani, D., Benetti, S., Testa, V., Hamuy, M., Antonelli, L. A., ...
We present photometric and spectroscopic observations of the gamma-ray burst GRB 021211 obtained during the late stages of its afterglow. The light curve shows a rebrightening occurring ~25 days...
