Latest Results from ALMA Polarimetry

Hiroshi Nagai, Kouichiro Nakanishi

Atacama Large Millimeter/submillimeter Array (ALMA) is a radio interferometry with an unprecedented sensitivity and calibration accuracy in millimeter and submillimeter bands at an altitude of 5,000 meters in Atacama desert .  ALMA started to offer the polarization observation capability with some limitation from Cycle 2, and brand-new results have just started to come out.  In this presentation, I will review basic performance, current observation capability, and near-term upgrades of ALMA polarimetry as well as the recent highlights of the polarization science.
