| Summary: | Planned rapid submillimeter (submm) gamma-ray-bursts (GRBs) follow-up observations conducted using the Greenland Telescope (GLT)
are presented. The GLT is a 12-m submm telescope to be located at the
top of the Greenland ice sheet, where the high altitude and dry
weather porvide excellent conditions for observations at submm
wavelengths. With its combination of wavelength window and rapid
responding system, the GLT will explore new insights on GRBs.
Summarizing the current achievements of submm GRB follow-ups, we
identify the following three scientific goals regarding GRBs: (1)
systematic detection of bright submm emissions originating from
reverse shock (RS) in the early afterglow phase, (2)
characterization of forward shock and RS emissions by capturing
their peak flux and frequencies and performing continuous
monitoring, and (3) detections of GRBs at a high redshift as a result of the
explosion of first generation stars through systematic rapid
follow-ups. The light curves and spectra calculated
by available theoretical models clearly show that the GLT could play
a crucial role in these studies. |
