Predicting Potential Host Galaxies of Supermassive Black Hole Binaries Based on Stellar Kinematics in Archival IFU Surveys

open access: yesThe Astrophysical Journal
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.

Statistics of the projected angles between the black-hole spin and the host-galaxy rotation axes from NewHorizon

open access: yesAstronomy & Astrophysics
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,

The Relation between AGN and Host-galaxy Properties in the JWST Era. I. Seyferts at Cosmic Noon are Obscured and Disturbed

open access: yesThe Astrophysical Journal
The morphology of a galaxy reflects the mix of physical processes occurring within and around it, offering indirect clues to its formation and evolution.

On the Tully–Fisher Relation for Active Galaxies. I. Evidence of Larger Scatter

open access: yesThe Astrophysical Journal
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

open access: yesThe Astrophysical Journal
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

open access: yesThe Astrophysical Journal
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

open access: yes, 2019
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.

Discrepancies between JWST Observations and Simulations of Quenched Massive Galaxies at z > 3: A Comparative Study with IllustrisTNG and ASTRID

open access: yesThe Astrophysical Journal
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 ...
