Future mmVLBI Research with ALMA: A European vision
R. P. J. Tilanus, T. P. Krichbaum, J. A. Zensus +165
Very long baseline interferometry at millimetre/submillimetre wavelengths (mmVLBI) offers the highest achievable spatial resolution at any wavelength in astronomy. The anticipated…
Zooming towards the Event Horizon - mm-VLBI today and tomorrow
T. P. Krichbaum, A. Roy, J. Wagner +21
Global VLBI imaging at millimeter and sub-millimeter wavelength overcomes the opacity barrier of synchrotron self-absorption in AGN and opens the direct view into sub-pc scale regi…
Long term Arecibo monitoring of the water megamaser in MG J0414+0534
P. Castangia, M. C. V. Impellizzeri, J. P. McKean +4
We monitored the 22 GHz maser line in the lensed quasar MG J0414+0534 at z=2.64 with the 300-m Arecibo telescope for almost two years to detect possible additional maser components…
Water vapour at high redshift: Arecibo monitoring of the megamaser in MG J0414+0534
P. Castangia, C. M. V. Impellizzeri, J. P. McKean +6
The study of water masers at cosmological distances would allow us to investigate the parsec-scale environment around powerful radio sources, to probe the physical conditions of th…
Conversion from linear to circular polarization in FPGA
Koyel Das, A. L. Roy, R. Keller +1
Context: Radio astronomical receivers are now expanding their frequency range to cover large (octave) fractional bandwidths for sensitivity and spectral flexibility, which makes th…
A search for gravitationally lensed water masers in dusty quasars and star-forming galaxies
J. P. McKean, C. M. V. Impellizzeri, A. L. Roy +5
Luminous extragalactic water masers are known to be associated with AGN and have provided accurate estimates for the mass of the central supermassive black hole and the size and st…
