The accuracy of the UV continuum as an indicator of the star formation rate in galaxies (2012)
Journal Article
Wilkins, S., Gonzalez-Perez, V., Lacey, C., & Baugh, C. (2012). The accuracy of the UV continuum as an indicator of the star formation rate in galaxies. Monthly Notices of the Royal Astronomical Society, 427(2), 1490-1496. https://doi.org/10.1111/j.1365-2966.2012.22092.x

The rest-frame intrinsic UV luminosity is often used as an indicator of the instantaneous star formation rate (SFR) in a galaxy. While it is in general a robust indicator of the ongoing star formation activity, the precise value of the calibration re...

Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions (2012)
Journal Article

Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions.

We combine the galaxy formation model GALFORM with the photon-dominated region code UCL−PDR to study the emission from the rotational transitions of 12CO (CO) in galaxies from z = 0 to z = 6 in the Λcold dark matter framework. GALFORM is used to pred... Read More about Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions.

The contribution of star-forming galaxies to fluctuations in the cosmic background light (2012)
Journal Article
Kim, H., Lacey, C., Cole, S., Baugh, C., Frenk, C., & Efstathiou, G. (2012). The contribution of star-forming galaxies to fluctuations in the cosmic background light. Monthly Notices of the Royal Astronomical Society, 425(4), 2674-2687. https://doi.org/10.1111/j.1365-2966.2012.21641.x

Star-forming galaxies which are too faint to be detected individually produce intensity fluctuations in the cosmic background light. This contribution needs to be taken into account as a foreground when using the primordial signal to constrain cosmol...

Can galactic outflows explain the properties of Ly α emitters? (2012)
Journal Article
Orsi, A., Lacey, C., & Baugh, C. (2012). Can galactic outflows explain the properties of Ly α emitters?. Monthly Notices of the Royal Astronomical Society, 425(1), 87-115. https://doi.org/10.1111/j.1365-2966.2012.21396.x

We study the properties of Graphic emitters in a cosmological framework by computing the escape of Graphic photons through galactic outflows. We combine the GALFORM semi-analytical model of galaxy formation with a Monte Carlo Graphic radiative transf... Read More about Can galactic outflows explain the properties of Ly α emitters?.

Predictions for the intrinsic UV continuum properties of star-forming galaxies and the implications for inferring dust extinction (2012)
Journal Article
Wilkins, S., Gonzalez-Perez, V., Lacey, C., & Baugh, C. (2012). Predictions for the intrinsic UV continuum properties of star-forming galaxies and the implications for inferring dust extinction. Monthly Notices of the Royal Astronomical Society, 424(2), 1522-1529. https://doi.org/10.1111/j.1365-2966.2012.21344.x

The observed ultraviolet continuum (UVC) slope is potentially a powerful diagnostic of dust obscuration in star-forming galaxies. However, the intrinsic slope is also sensitive to the form of the stellar initial mass function and to the recent star f...

The nature and descendants of Lyman-break galaxies in the Λ cold dark matter cosmology (2012)
Journal Article
González, J., Lacey, C., Baugh, C., Frenk, C., & Benson, A. (2012). The nature and descendants of Lyman-break galaxies in the Λ cold dark matter cosmology. Monthly Notices of the Royal Astronomical Society, 423(4), 3709-3726. https://doi.org/10.1111/j.1365-2966.2012.21167.x

We predict the formation histories, properties and descendants of Lyman-break galaxies (LBGs) in the Λ cold dark matter cosmology. In our model, which incorporates a top-heavy initial mass function in starbursts, we find that most LBGs are starbursts...

The evolution of active galactic nuclei across cosmic time : what is downsizing? (2012)
Journal Article

We use a coupled model of the formation and evolution of galaxies and black holes (BHs) to study the evolution of active galactic nuclei (AGNs) in a cold dark matter universe. The model is embedded in the galaxy formation code GALFORM and predicts th... Read More about The evolution of active galactic nuclei across cosmic time : what is downsizing?.
