Query: A next-generation Very Large Array   In this proceeding, we summarize the key science goals and reference design
for a next-generation Very Large Array (ngVLA) that is envisaged to operate in
the 2030s. The ngVLA is an interferometric array with more than 10 times the
sensitivity and spatial resolution of the current VLA and ALMA, that will
operate at frequencies spanning $\sim 1.2 -116$ GHz, thus lending itself to be
highly complementary to ALMA and the SKA1. As such, the ngVLA will tackle a
broad range of outstanding questions in modern astronomy by simultaneously
delivering the capability to: unveil the formation of Solar System analogues;
probe the initial conditions for planetary systems and life with
astrochemistry; characterize the assembly, structure, and evolution of galaxies
from the first billion years to the present; use pulsars in the Galactic center
as fundamental tests of gravity; and understand the formation and evolution of
stellar and supermassive blackholes in the era of multi-messenger astronomy.
