Description
Gravitational-wave astronomy has achieved remarkable progress over the
past decades, detecting waves across a wide range of frequencies.
However, the band around one Hz remains unexplored. This band is vital
for studying some of the most fascinating sources, including
intermediate-mass binary black hole mergers, early inspiralling compact
binaries, and possibly cosmic inflation. The Artificial Precision Timing
Array (APTA), a new detector concept based on pulsar timing principles,
aims to access this intriguing band. APTA aims to use
precision-clock-carrying satellites that emit pulsing signals towards a
central point. This talk will discuss the APTA concept and the clock
precision required for its successful detection of gravitational waves.
With advancements in clock technology anticipated within the next
decade, APTA could detect a wide range of astrophysical sources, opening
a new research area focused on designing and constructing
gravitational-wave detectors based on pulsar timing principles.
