We use the energy-balance code MAGPHYS to determine stellar and dust masses, and dust corrected star formation rates for over 200 000 GAMA galaxies, 170 000 G10-COSMOS galaxies, and 200 000 3D-HST galaxies. Our values agree well with previously repor... Read More about GAMA/G10-COSMOS/3D-HST: the 0 < z < 5 cosmic star formation history, stellar-mass, and dust-mass densities.

The origin of fast molecular outflows in quasars: Molecule formation in AGN-driven galactic winds (2017)
Journal Article
Richings, A. J., & Faucher-Giguère, C. A. (2018). The origin of fast molecular outflows in quasars: Molecule formation in AGN-driven galactic winds. Monthly notices of the Royal Astronomical Society, 474(3), 3673-3699. https://doi.org/10.1093/mnras/stx3014

We explore the origin of fast molecular outflows that have been observed in active galactic nuclei (AGNs). Previous numerical studies have shown that it is difficult to create such an outflow by accelerating existing molecular clouds in the host gala...

Flickering AGN can explain the strong circumgalactic OVI observed by COS-Halos (2017)
Journal Article
Oppenheimer, B. D., Segers, M., Schaye, J., Richings, A. J., & Crain, R. A. (2018). Flickering AGN can explain the strong circumgalactic OVI observed by COS-Halos. Monthly notices of the Royal Astronomical Society, 474(4), 4740-4755. https://doi.org/10.1093/mnras/stx2967

Proximity zone fossils (PZFs) are ionization signatures around recently active galactic nuclei (AGNs) where metal species in the circumgalactic medium remain overionized after the AGNs have shut offdue to their long recombination time scales. We expl... Read More about Flickering AGN can explain the strong circumgalactic OVI observed by COS-Halos.
