Recent sensitive ALMA observations have revealed that a substantial fraction of galaxies
which are bright in submm emission are often dark in optical images, making it exceedingly
difficult to detect optical emission lines and obtain an unambiguous redshift.
This can have broad consequences since the uncertainties in redshift can severely hamper
our ability to efficiently conduct surveys which will ultimately connect various scientific fields,
for example, blind galaxy/cluster searches, starburst-AGN-QSO connection,
deep line surveys towards the lensed QSO, spatial variation of the CGM,
reproducibility in cosmological simulations.
The scope of this workshop is to review the recent progress in understanding
the nature of optically-dark mm/submm galaxy population and discuss possible science cases
and strategies for the next call for observational proposals (e.g., ALMA/JWST/Chandra/VLA).
Other highly related and complementary topics will be covered in the workshop as well.
We are planning to have a hybrid mode workshop.
