Am Montag, den 24. Juni 2024, um 12:00 Uhr c.t., findet der nächste Termin unseres Physikalischen Kolloquiums statt.
Referent ist Prof. Dr. Matthias Kadler (Universität Würzburg) zum Thema „LEVERAGE – CONCEPT FOR A LONG-BASELINE EXTENSION IN NEXTGENERATION VLBI EXPERIMENTS AND RAPID-RESPONSE ARRAY“.
The next decades of radio astronomy will be dominated by large facilities of superior
sensitivity. Between 1GHz and 15GHz, strong synergies can be developed between the
next-generation Very Large Array (ngVLA) and the Square Kilometre Array (SKA),
specifically the SKA-mid. Towards higher frequencies, the ngVLA will be able to coobserve
with other frontline facilities including the EVN (at 1-43 GHz), and the GMVA
(at 43-86 GHz). In this talk, I will discuss the possibility of enhancing these synergies
with an array of radio antennas in Germany to be operated as a stand-alone facility, as
well as a complement to the ngVLA, SKA-mid, EVN, and GMVA in VLBI and studies of
transients. LEVERAGE is a concept for an array of two to four radio-antenna stations
operating in the mid-to-high frequency range (up to 120GHz) with baselines between
500km and 1000km, which will significantly enhance the science capabilities of both the
SKA and ngVLA in terms of submilliarcsecond-scale image reconstruction and flexibility
in reacting to short transient events. Moreover, the LEVERAGE concept offers high
efficiency as a stand-alone instrument and can be optimized to localize and follow-up
radio transients with a faster reaction time than the larger next-generation facilities. The facility may support special
modes that are difficult to realize on the full large next-generation facilities
or are going beyond their scope such as long uninterrupted integrations, high-cadence observations, longterm monitoring or broader simultaneous frequency coverage.
