Strongly Lensed Supermassive Black Hole Binaries as Nanohertz Gravitational-Wave Sources

Nicole M. Khusid, Chiara M. F. Mingarelli, Priyamvada Natarajan +2

Supermassive black hole binary systems (SMBHBs) should be the most powerful sources of gravitational waves (GWs) in the Universe. Once Pulsar Timing Arrays (PTAs) detect the stocha…

Milliarcsecond X-ray astrometry to resolve inner regions of AGN at $z > 1$ using gravitational lensing

C. Spingola, D. Schwartz, A. Barnacka

We report the localization of the X-ray emission from two strongly lensed AGN, CLASS B0712+472 ( $z = 1.34$ ) and CLASS B1608+656 ( $z = 1.394$ ). We obtain milliarcsecond X-ray astrometry…
