Supermassive black hole binaries (SMBHBs) at the centers of galaxies emit continuous gravitational waves (GWs) at nanohertz frequencies, and ongoing pulsar timing array (PTA) experiments aim to detect the first individual system.

Understanding the alignment between active galactic nucleus (AGN) jets and their host galaxies is crucial for interpreting AGN unification models, jet feedback processes, and the coevolution of galaxies and their central black holes (BHs). In this study,

On the Tully–Fisher Relation for Active Galaxies. I. Evidence of Larger Scatter
We present an investigation of the Tully–Fisher (TF) relation solely for galaxies hosting an active galactic nucleus (AGN). Using 22 galaxies with primary, z -independent distances, we find that active galaxies exhibit significantly larger scatter about ...

Quantifying the Active Galactic Nucleus Fraction in Cosmic Voids via Mid-infrared Variability
Observations and theoretical simulations suggest that the large-scale environment plays a significant role in how galaxies form and evolve and, in particular, whether and when galaxies host an actively accreting supermassive black hole in their center (i.

The Host Galaxies of Active Galactic Nuclei with Direct Black Hole Mass Measurements
Reverberation mapping (RM) determines the mass of black holes (BHs) in active galactic nuclei (AGNs) by resolving the BH gravitational sphere of influence in the time domain.

Structures of Dusty and AGN Host Galaxies
I will present a study of connection between star formation, active galactic nucleus (AGN), and galaxy morphology. By fitting optical to far-IR photometry with state-of-the-art spectral energy distribution (SED) techniques, we derive stellar masses, star formation rates, dust properties, and AGN contribution in galaxies over the whole COSMOS field. Our

Recent JWST observations have uncovered an unexpectedly large population of massive quiescent galaxies at z > 3. Using the cosmological simulations IllustrisTNG and ASTRID , we identify analogous galaxies and investigate their abundance, formation ...
