SUMMARY:Monthly Meeting June
DESCRIPTION:Precision Metrology of the Sky: Advances and Problems of VLBI Astrometry \nThe use of Very Long Baseline Interferometry (VLBI) technique revolutionizes modern astrometry. It surpasses Gaia’s positional accuracy and allows conducting distance (parallax) measurements in the galactic plane far beyond the reach of optical telescopes. In this talk I will describe the method and report on some recent developments at the Warkworth Radio Astronomical Observatory in the field of radio (VLBI) astrometry. We will discuss problems of positional measurements in radio astronomy\, talk about effects of radio source structure on determination of its precise position on the sky\, about the perspectives of mapping spiral arms beyond the Galactic Centre with the use of methanol maser emission sources\, learn about the “Gaia Sausage” as well as of a new class of pulsars based on rotating white dwarfs (rather than neutron stars). \nProfessor Sergei Gulyaev is the founder and director of AUT’s Institute for Radio Astronomy and Space Research (IRASR). Under his direction\, the institute has built an observatory at Warkworth\, north of Auckland\, equipped with a 12-metre and a 30-metre radio telescope. \nA hallmark of Professor Gulyaev’s research is his collaborative approach with the IRASR forging working relationships with radio astronomy and national aeronautical organisations around the world\, including NASA\, SpaceX\, ESA (European Space Agency) and JAXA (Japanese Space Agency). \nIn one of many collaborative projects Professor Gulyaev and his team have used a technique known as Very Long Baseline Interferometry (VLBI) to link the Warkworth radio telescope with observatories across Australia\, including ASKAP (Australian SKA Pathfinder). Acting as one virtual radio telescope they were able to get greater resolution or sharper cosmic images from their observations.

SUMMARY:Film Night June 27
DESCRIPTION:We are running two films tonight: \nSearch For the Edge of Space\nThe universe has long captivated us with its immense scales of distance and time. Many astronomers today have come to believe that what we can see represents only a small fraction of all there is. They are pioneering bold new theories that describe a cosmic landscape that extends far beyond the limits of our vision. What lies beyond the streams of galaxies that extend as far as our telescopes can see? Where does it all end? How do we fit within it? \nBBC The Sky at Night Destination Moon 2022\n2022 marks the fiftieth year since an astronaut last set foot on the moon. The Sky at Night team looks back at the legacy of the Apollo programme and forward to the future of lunar exploration.
