Small-scale Substructure in Dark Matter Haloes: Where Does Galaxy Formation Come to an End?
James E. Taylor, Joseph Silk, Arif Babul
Models of structure formation based on cold dark matter predict that most of the small dark matter haloes that first formed at high redshift would have merged into larger systems b…
The Satellite-substructure Connection
James E. Taylor, Arif Babul, Joseph Silk
We describe our recent attempts to model substructure in dark matter halos down to very small masses, using a semi-analytic model of halo formation. The results suggest that numeri…
Massive black hole remnants of the first stars III: observational signatures from the past
Ranty R. Islam, James E. Taylor, Joseph Silk
The first stars forming in minihaloes at redshifts greater than 20 may have been very massive and could have left behind massive black hole (MBH) remnants. In previous papers we in…
Massive black hole remnants of the first stars II: optical and X-ray signatures in present-day galactic haloes
Ranty R. Islam, James E. Taylor, Joseph Silk
The first stars forming in minihaloes at redshifts greater than 20 may have been very massive and could have left behind massive black hole (MBH) remnants. In a previous paper we i…
Massive black hole remnants of the first stars I: abundance in present-day galactic haloes
Ranty R. Islam, James E. Taylor, Joseph Silk
We investigate the possibility that present-day galaxies and their dark matter haloes contain a population of massive black holes (MBHs) that form by hierarchical merging of the bl…
Observing the Sunyaev-Zel'dovich Effect Closer to Home
James E. Taylor, Kavilan Moodley, J. M. Diego
Hot gas trapped in a dark matter halo will produce a decrement in the surface brightness of the microwave background, the Sunyaev-Zel'dovich (SZ) effect. While massive clusters pro…
