A new determination of the local dark matter density from the kinematics of K dwarfs
Silvia Garbari, Chao Liu, Justin I. Read +1
We apply a new method to determine the local disc matter and dark halo matter density to kinematic and position data for \sim2000 K dwarf stars taken from the literature. Our metho…
Thermal instabilities in cooling galactic coronae: fuelling star formation in galactic discs
Alexander Hobbs, Justin Read, Chris Power +1
We investigate the means by which cold gas can accrete onto Milky Way mass galaxies from a hot corona of gas, using a new smoothed particle hydrodynamics code, 'SPHS'. We find that…
Cusp-core transformations in dwarf galaxies: observational predictions
Romain Teyssier, Andrew Pontzen, Yohan Dubois +1
The presence of a dark matter core in the central kiloparsec of many dwarf galaxies has been a long standing problem in galaxy formation theories based on the standard cold dark ma…
Cosmology and fundamental physics with the Euclid satellite
Luca Amendola, Stephen Appleby, David Bacon +60
Euclid is a European Space Agency medium class mission selected for launch in 2019 within the Cosmic Vision 2015-2025 programme. The main goal of Euclid is to understand the origin…
The mass distribution of the Fornax dSph: constraints from its globular cluster distribution
David R. Cole, Walter Dehnen, Justin I. Read +1
Uniquely among the dwarf spheroidal (dSph) satellite galaxies of the Milky Way, Fornax hosts globular clusters. It remains a puzzle as to why dynamical friction has not yet dragged…
