Abstract:	We propose to append five 12-m antennas within 300-km from ALMA to realize high angular resolution of < 1 mas and sensitivity to detect Tb < 1000 K. This ALMA extended array offers a new parameter space of “Thermal universe with VLBI resolution”. Proposed science case includes black-hole formation in sub-mm galaxies, mass accretion processes onto protostars, imaging stellar photospheres, distance measurements of stars, and so on. The array also functions as a part of sub-mm VLBI that targets black-hole imaging.
