Extending the Globular Cluster System-Halo Mass Relation to the Lowest Galaxy Masses

Duncan A. Forbes, Justin I. Read, Mark Gieles +1

High mass galaxies, with halo masses , reveal a remarkable near-linear relation between their globular cluster (GC) system mass and their host galaxy…

The alignment is in their stars: on the spin-alignment of stars in star clusters

Ramon Rey-Raposo, Justin Read

We simulate star formation in two molecular clouds extracted from a larger disc-galaxy simulation with a spatial resolution of ~0.1 pc, one exiting a spiral arm dominated by compre…

Dark matter heats up in dwarf galaxies

J. I. Read, M. G. Walker, P. Steger

Gravitational potential fluctuations driven by bursty star formation can kinematically 'heat up' dark matter at the centres of dwarf galaxies. A key prediction of such models is th…

On the early evolution of Local Group dwarf galaxy types: star formation and supernova feedback

Jose R. Bermejo-Climent, Giuseppina Battaglia, Carme Gallart +8

According to star formation histories (SFHs), Local Group dwarf galaxies can be broadly classified in two types: those forming most of their stars before () and t…

The case for a cold dark matter cusp in Draco

J. I. Read, M. G. Walker, P. Steger

We use a new mass modelling method, GravSphere, to measure the central dark matter density profile of the Draco dwarf spheroidal galaxy. Draco's star formation shut down long ago,…

A Gaia DR2 search for dwarf galaxies towards Fermi-LAT sources: implications for annihilating dark matter

Ioana Ciucă, Daisuke Kawata, Shin'ichiro Ando +3

We make a first attempt to find dwarf galaxies in eight \Fermi-LAT extended, unassociated, source fields using \Gaia\ DR2. We probe previously unexplored heliocentric distances of…
