Наслов предавања: COMBINING TWO EXTREME IMAGING FRONTIERS IN THE QUEST FOR SUPERMASSIVE BINARY BLACK HOLE
 
Апстракт: Imaging has always been and remains to be at the forefront of astronomical research because it has two distinct frontiers.
One of the extreme ends consists of a fleet of large survey telescopes that scan large regions of the entire sky in order to compile inventories of objects that are ever more complete. On the opposite side is  a substantial population of greater resolution and higher quality imaging tools, which are capable of scanning individual objects with vision that is ever more sharp.

Understanding the nature of spacetime and gravity will be one of the primary challenges of fundamental research in the future decades.The entirety of the event that takes place in our universe occurs inside the context of spacetime, which stands as the arena. Particular attention will be paid to possible supermassive binary black holes (SMBBH) as a source of 'ripples' in space-time.
New large surveys such as the Vera C. Rubin Legacy Survey of Space and Time (LSST) can produce a view of the deep universe with a high cadence over decade, making it possible to combine both extremes of imaging frontiers.
We describe here a work that is now in progress to hybridise the LSST, and nearby future sharp vision instruments  quest for SMBBH.
This research is conducted by LSST SER-SAG Team.
