HL Tau with ALMA

A new installment of ALMA Science Verification (SV) data is available. This release contains several new datasets corresponding to four targets observed as part of the 2014 ALMA Long Baseline Campaign in order to demonstrate the long baseline (~10 km), high angular resolution, capability of ALMA. Maximum baselines used ranged from 12.2 to 14.9 km.

The SV targets are:

  • Juno: observations of continuum in Band 6 (233 GHz)
  • Mira: observations of several SiO transitions (isotopologues and vibrational states) and continuum in Bands 3 and 6
  • HL Tau: observations of continuum and spectral line in Band 3, and continuum only in Bands 6 & 7
  • SDP.81: observations of continuum and spectral lines in Bands 4, 6 & 7

Details of the Campaign and the targets (sets 13-16) are listed on the ALMA SV webpage.
