Astrophysical Population Coordinates for Supermassive Black Hole Binaries in Pulsar Timing Array Inference
Yikun Li, Muhammad Ahmad, Shaoguang Guo +1
Pulsar timing arrays can probe the population physics of supermassive black-hole binaries through the nanohertz gravitational-wave background. We construct a phenomenological forwa…

Interactions between the jet and disk wind in a nearby radio intermediate quasar III Zw 2
Ailing Wang, Tao An, Shaoguang Guo +13
Disk winds and jets are ubiquitous in active galactic nuclei (AGN), and how these two components interact remains an open question. We study the radio properties of a radio-interme…
