Abstract
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
