Future mmVLBI Research with ALMA: A European vision
  Very long baseline interferometry at millimetre/submillimetre wavelengths (mmVLBI) offers the highest achievable spatial resolution at any wavelength in astronomy. The anticipated inclusion of ALMA as a phased array into a global VLBI network will bring unprecedented sensitivity and a transformational leap in capabilities for mmVLBI. Building on years of pioneering efforts in the US and Europe the ongoing ALMA Phasing Project (APP), a US-led international collaboration with MPIfR-led European contributions, is expected to deliver a beamformer and VLBI capability to ALMA by the end of 2014 (APP: Fish et al. 2013, arXiv:1309.3519).   This report focuses on the future use of mmVLBI by the international users community from a European viewpoint. Firstly, it highlights the intense science interest in Europe in future mmVLBI observations as compiled from the responses to a general call to the European community for future research projects. A wide range of research is presented that includes, amongst others:   - Imaging the event horizon of the black hole at the centre of the Galaxy   - Testing the theory of General Relativity an/or searching for alternative theories   - Studying the origin of AGN jets and jet formation   - Cosmological evolution of galaxies and BHs, AGN feedback   - Masers in the Milky Way (in stars and star-forming regions)   - Extragalactic emission lines and astro-chemistry   - Redshifted absorption lines in distant galaxies and study of the ISM and circumnuclear gas   - Pulsars, neutron stars, X-ray binaries   - Testing cosmology   - Testing fundamental physical constants
