PublicaciónStrong 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...

PublicaciónStudy 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...

PublicaciónTesting 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...

PublicaciónTesting 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...

CharlaThe (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...

PublicaciónThe 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...

PublicaciónThe Alignment of Dark Matter Halos with the Cosmic Web
We investigate the orientation of the axes and angular momentum of dark matter halos with respect to their neighboring voids using high-resolution N-body...

PublicaciónThe BOSS Emission-line Lens Survey. III. Strong Lensing of Lyα Emitters by Individual Galaxies
We introduce the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey GALaxy-Lyα EmitteR sYstems (BELLS GALLERY) Survey, which is a Hubble...
