Embedding globular clusters in dark matter minihalos solves the cusp-core and timing problems in the Fornax dwarf galaxy
Pierre Boldrini, Roya Mohayaee, Joseph Silk
We use a fully GPU -body code to demonstrate that dark matter minihalos, as a new component of globular clusters, resolve both the timing and cusp-core problems in Fornax if the…
Chronos: A NIR spectroscopic survey to target the most important phases of galaxy evolution across cosmic time
I. Ferreras, M. Cropper, R. Sharples +15
(Abridged summary) Responding to ESA's Voyage 2050 call to define the long-term plan for the future space missions that will address the astrophysics science questions during the 2…
Exploring a new definition of the green valley and its implications
James Angthopo, Ignacio Ferreras, Joseph Silk
The distribution of galaxies on a colour-magnitude diagram reveals a bimodality, featuring a passively evolving red sequence and a star-forming blue cloud. The region between these…
AGN in dwarf galaxies: frequency, triggering processes and the plausibility of AGN feedback
Sugata Kaviraj, Garreth Martin, Joseph Silk
While AGN are considered to be key drivers of the evolution of massive galaxies, their potentially significant role in the dwarf-galaxy regime (M*< 10^9 MSun) remains largely unexp…
Ultra-diffuse galaxies without dark matter
Joseph Silk
I develop a high velocity galaxy collision model to explain a rare but puzzling phenomenon, namely the apparent existence of ultra-diffuse galaxies with little dark matter. Predict…
Feedback by supermassive black holes in galaxy evolution: impacts of accretion and outflows on the star formation rate
Mojtaba Raouf, Joseph Silk, Stanislav S. Shabala +4
We describe a physical model of the outflows produced as a result of gas accretion onto a black hole, and the resultant changes to star formation rates and efficiencies in galaxies…
High-redshift quasars and their host galaxies I: kinematical and dynamical properties and their tracers
Alessandro Lupi, Marta Volonteri, Roberto Decarli +3
Observations of high-redshift quasars provide information on the massive black holes (MBHs) powering them and the galaxies hosting them. Current observations of hosts…
