Exploring how radio-emitting active galactic nuclei (AGNs) behave and evolve with time is critical for understanding how AGN feedback impacts galaxy evolution. In this work, we investigate the relationship between 1.4 GHz radio continuum AGN luminosi... Read More about SMBH accretion properties of radio-selected AGN out to z ∼ 4.

Obscured Active Galactic Nuclei (2018)
Journal Article
Hickox, R., & Alexander, D. (2018). Obscured Active Galactic Nuclei. Annual Review of Astronomy and Astrophysics, 56, 625-671. https://doi.org/10.1146/annurev-astro-081817-051803

Active galactic nuclei (AGN) are powered by the accretion of material onto a supermassive black hole (SMBH) and are among the most luminous objects in the Universe. However, the huge radiative power of most AGN cannot be seen directly, as the accreti... Read More about Obscured Active Galactic Nuclei.

Does black-hole growth depend on the cosmic environment? (2018)
Journal Article
Yang(杨光), G., Brandt, W., Darvish, B., Chen(陳建廷), C.-T., Vito, F., Alexander, D., Bauer, F., & Trump, J. (2018). Does black-hole growth depend on the cosmic environment?. Monthly Notices of the Royal Astronomical Society, 480(1), 1022-1042. https://doi.org/10.1093/mnras/sty1910

It is well known that environment affects galaxy evolution, which is broadly related to supermassive black hole (SMBH) growth. We investigate whether SMBH evolution also depends on host-galaxy local (sub-Mpc) and global (≈1–10 Mpc) environment. We co...
