We examine the outskirts of galaxy clusters in the C-EAGLE simulations to quantify the 'edges' of the stellar and dark matter distribution. The radius of the...

PublicationStellar Tidal Streams in Spiral Galaxies of the Local Volume: A Pilot Survey with Modest Aperture Telescopes
Within the hierarchical framework for galaxy formation, minor merging and tidal interactions are expected to shape all large galaxies to the present day. As a...

PublicationStellar velocity profiles and line strengths out to four effective radii in the early-type galaxies NGC3379 and 821
We use the integral-field spectrograph SAURON to measure the stellar line-of-sight velocity distribution and absorption line strengths out to four effective...

PublicationStrong lensing reveals jets in a sub-microJy radio-quiet quasar
We present e-MERLIN and European VLBI Network observations which reveal unambiguous jet activity within radio-quiet quasar HS 0810+2554. With an intrinsic flux...

PublicationStudy of the Sextans dwarf spheroidal galaxy from the DART Ca II triplet survey
We use Very Large Telescope (VLT)/Fibre Large Array Multi Element Spectrograph (FLAMES) intermediate-resolution (R˜ 6500) spectra of individual red giant branch...

PublicationTesting Axion Physics in a Josephson Junction Environment
We suggest that experiments based on Josephson junctions, SQUIDS, and coupled Josephson qubits may be used to construct a resonant environment for dark matter...

PublicationTesting the conditional mass function of dark matter haloes against numerical N-body simulations
We compare the predicted conditional mass function (CMF) of dark matter haloes from two theoretical prescriptions against numerical N-body simulations, both in...

TalkThe (very) small-scale structure of dark matter halos
In our now-standard picture for the growth of structure, dark matter halos are the basic unit of nonlinear structure in the present Universe. I will report...

PublicationThe ALHAMBRA survey: Estimation of the clustering signal encoded in the cosmic variance
Aims: The relative cosmic variance (σv) is a fundamental source of uncertainty in pencil-beam surveys and, as a particular case of count-in-cell statistics, can...
