DESHIMA 2.0: Rapid redshift surveys and multi-line spectroscopy of dusty
  galaxies
  We present a feasibility study for the high-redshift galaxy part of the
Science Verification Campaign with the 220-440 GHz DESHIMA 2.0 integrated
superconducting spectrometer on the ASTE telescope. The first version of the
DESHIMA 2.0 chip has been recently manufactured and tested in the lab. Based on
these realistic performance measurements, we evaluate potential target samples
and prospects for detecting the [CII] and CO emission lines. The planned
observations comprise two distinct, but complementary objectives: (1) acquiring
spectroscopic redshifts for dusty galaxies selected in far-infrared/mm-wave
continuum surveys; (2) multi-line observations to infer physical conditions in
dusty galaxies.
