Predictions for the detection of tidal streams with Gaia using great-circle methods (2017)
Journal Article
Mateu, C., Cooper, A., Font, A., Aguilar, L., Frenk, C., Cole, S., …McCarthy, I. (2017). Predictions for the detection of tidal streams with Gaia using great-circle methods. Monthly Notices of the Royal Astronomical Society, 469(1), 721-743. https://doi.org/10.1093/mnras/stx872

The Gaia astrometric mission may offer an unprecedented opportunity to discover new tidal streams in the Galactic halo. To test this, we apply nGC3, a great-circle-cell count method that combines position and proper motion data to identify streams, t...

Addressing the too big to fail problem with baryon physics and sterile neutrino dark matter (2017)
Journal Article

Monthly Notices of the Royal Astronomical Society, 468(3), 2836-2849. https://doi.org/10.1093/mnras/stx621

N-body dark matter simulations of structure formation in the Λ cold dark matter (ΛCDM) model predict a population of subhaloes within Galactic haloes that have higher central densities than inferred for the Milky Way satellites, a tension known as th...

Projection effects in the strong lensing study of subhaloes (2017)
Journal Article
Li, R., Frenk, C., Cole, S., Wang, Q., & Gao, L. (2017). Projection effects in the strong lensing study of subhaloes. Monthly Notices of the Royal Astronomical Society, 468(2), 1426-1432. https://doi.org/10.1093/mnras/stx554

The defining characteristic of the cold dark matter (CDM) hypothesis is the presence of a very large number of low-mass haloes, too small to have made a visible galaxy. Other hypotheses for the nature of the dark matter, such as warm dark matter (WDM... Read More about Projection effects in the strong lensing study of subhaloes.

Gravitational redshift and asymmetric redshift-space distortions for stacked clusters (2017)
Journal Article
Cai, Y., Kaiser, N., Cole, S., & Frenk, C. (2017). Gravitational redshift and asymmetric redshift-space distortions for stacked clusters. Monthly Notices of the Royal Astronomical Society, 468(2), 1981-1993. https://doi.org/10.1093/mnras/stx469

We derive the expression for the observed redshift in the weak field limit in the observer's past light cone, including all relativistic terms up to second order in velocity. We then apply it to compute the cluster–galaxy cross-correlation functions... Read More about Gravitational redshift and asymmetric redshift-space distortions for stacked clusters.

The far infra-red SEDs of main sequence and starburst galaxies (2017)
Journal Article
Cowley, W., Béthermin, M., Lagos, C. D. P., Lacey, C., Baugh, C., & Cole, S. (2017). The far infra-red SEDs of main sequence and starburst galaxies. Monthly Notices of the Royal Astronomical Society, 467(1), 1231-1248. https://doi.org/10.1093/mnras/stx165

We compare observed far infrared/sub-millimetre (FIR/sub-mm) galaxy spectral energy distributions (SEDs) of massive galaxies (M⋆ ≳ 1010 h−1 M⊙) derived through a stacking analysis with predictions from a new model of galaxy formation. The FIR SEDs of... Read More about The far infra-red SEDs of main sequence and starburst galaxies.
