Constraining sterile neutrino cosmologies with strong gravitational lensing observations at redshift z ∼ 0.2 (2018)
Journal Article
Vegetti, S., Despali, G., Lovell, M., & Enzi, W. (2018). Constraining sterile neutrino cosmologies with strong gravitational lensing observations at redshift z ∼ 0.2. Monthly Notices of the Royal Astronomical Society, 481(3), 3661-3669. https://doi.org/10.1093/mnras/sty2393

We use the observed amount of subhaloes and line-of-sight dark matter haloes in a sample of 11 gravitational lens systems from the Sloan Lens ACS Survey to constrain the free-streaming properties of the dark matter particles. In particular, we combin... Read More about Constraining sterile neutrino cosmologies with strong gravitational lensing observations at redshift z ∼ 0.2.

The fraction of dark matter within galaxies from the IllustrisTNG simulations (2018)
Journal Article
Lovell, M. R., Pillepich, A., Genel, S., Nelson, D., Springel, V., Pakmor, R., …Hernquist, L. (2018). The fraction of dark matter within galaxies from the IllustrisTNG simulations. Monthly Notices of the Royal Astronomical Society, 481(2), 1950-1975. https://doi.org/10.1093/mnras/sty2339

We use the IllustrisTNG (TNG) cosmological simulations to provide theoretical expectations for the dark matter mass fractions (DMFs) and circular velocity profiles of galaxies. TNG predicts flat circular velocity curves for z = 0 Milky Way (MW)-like... Read More about The fraction of dark matter within galaxies from the IllustrisTNG simulations.

ETHOS – an effective theory of structure formation: predictions for the high-redshift Universe – abundance of galaxies and reionization (2018)
Journal Article
Lovell, M. R., Zavala, J., Vogelsberger, M., Shen, X., Cyr-Racine, F.-Y., Pfrommer, C., Sigurdson, K., Boylan-Kolchin, M., & Pillepich, A. (2018). ETHOS – an effective theory of structure formation: predictions for the high-redshift Universe – abundance of galaxies and reionization. Monthly Notices of the Royal Astronomical Society, 477(3), 2886-2899. https://doi.org/10.1093/mnras/sty818

We contrast predictions for the high-redshift galaxy population and reionization history between cold dark matter (CDM) and an alternative self-interacting dark matter model based on the recently developed ETHOS framework that alleviates the small-sc...
