The evolution of SMBH spin and AGN luminosities for z < 6 within a semi-analytic model of galaxy formation (2019)
Journal Article
Griffin, A. J., Lacey, C. G., Gonzalez-Perez, V., del P Lagos, C., Baugh, C. M., & Fanidakis, N. (2019). The evolution of SMBH spin and AGN luminosities for z < 6 within a semi-analytic model of galaxy formation. Monthly Notices of the Royal Astronomical Society, 487(1), 198-227. https://doi.org/10.1093/mnras/stz1216

Understanding how Active Galactic Nuclei (AGN) evolve through cosmic time allows us to probe the physical processes that control their evolution. We use an updated model for the evolution of masses and spins of supermassive black holes (SMBHs), coupl...

Cosmic CARNage II: the evolution of the galaxy stellar mass functionin observations and galaxy formation models. Monthly Notices of the Royal Astronomical Society, 480(1), 1197-1210. https://doi.org/10.1093/mnras/sty1870

We present a comparison of the observed evolving galaxy stellar mass functions with the predictions of eight semi-analytic models and one halo occupation distribution model. While most models are able to fit the data at low redshift, some of them str...

On the frequency of star-forming galaxies in the vicinity of powerful AGNs: The case of SMM J04135+10277 (2017)
Journal Article
Fogasy, J., Knudsen, K., Lagos, C., Drouart, G., & Gonzalez-Perez, V. (2017). On the frequency of star-forming galaxies in the vicinity of powerful AGNs: The case of SMM J04135+10277. Astronomy & Astrophysics, 597, Article A123. https://doi.org/10.1051/0004-6361/201628173

Context. In the last decade several massive molecular gas reservoirs were found <100 kpc distance from active galactic nuclei (AGNs), residing in gas-rich companion galaxies. The study of AGN–gas-rich companion systems opens the opportunity to determ...

Clustering of EROs from UKIDSS DXS and Pan-STARRS PS1 (2013)
Presentation / Conference Contribution
Kim, J.-W., Edge, A. C., Wake, D., Gonzalez-Perez, V., Baugh, C. M., & Lacey, C. G. (2013, July). Clustering of EROs from UKIDSS DXS and Pan-STARRS PS1. Presented at IAU Symposium

We have measured the angular two-point correlation function of EROs. The halo model is fitted to the observed clustering, and dark matter halo mass, bias and satellite fraction are estimated in three redshift bins. We also compare our results with th...

Extremely Red Objects in a Hierarchical Universe (2010)
Presentation / Conference Contribution
Baugh, C., Lacey, C., Almeida, C., & Gonzalez-Perez, V. (2010, December). Extremely Red Objects in a Hierarchical Universe. Presented at Highlights of Spanish Astrophysics V, Santander

We analyse whether hierarchical formation models based on Λ Cold Dark Matter Cosmology can produce enough massive red galaxies to match observations. For this purpose, we compare observations with the predictions from two published models for the abu... Read More about Extremely Red Objects in a Hierarchical Universe.
