Satellite luminosities in galaxy groups [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2007
Halo model interpretations of the luminosity dependence of galaxy clustering assume that there is a central galaxy in every sufficiently massive halo, and that this central galaxy is very different from all the others in the halo. The halo model decomposition makes the remarkable prediction that the mean luminosity of the non-central galaxies in a halo

Potential impact of the Sagittarius dwarf galaxy on the formation of young O-rich stars [PDF]

open access: yesNature Communications
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notable star formation events over the past 4 Gyr, likely triggered by ...

The abundance and radial distribution of satellite galaxies [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2005
Using detailed mock galaxy redshift surveys (MGRSs) we investigate the abundance and radial distribution of satellite galaxies. The mock surveys are constructed using the conditional luminosity function (CLF), and are compared against data from the 2dFGRS.

The colours of satellite galaxies in groups and clusters [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2008
Current models of galaxy formation predict satellite galaxies in groups and clusters that are redder than observed. We investigate the effect on the colours of satellite galaxies produced by the ram pressure stripping of their hot gaseous atmospheres as the satellites orbit within their parent halo. We incorporate a model of the stripping process based

Anisotropy in the Distribution of Satellite Galaxy Orbits [PDF]

open access: bronzeThe Astrophysical Journal, 2004
Nearby clusters such as Virgo and Coma possess galaxy distributions that tend to be aligned with the principal axis of the cluster itself. This has also been confirmed by a recent statistical analysis of some 300 Abell clusters, where the effect has been linked to the dynamical state of the cluster.

Formation of Transitional cE/UCD Galaxies through Massive/Dwarf Disc Galaxy Mergers

open access: yesGalaxies, 2023
The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky Way type were studied in detail. The remnant of such interaction after numerous crossings of the satellite through the disc of the main galaxy was a compact ...

Anisotropic Satellite Galaxy Quenching: A Unique Signature of Energetic Feedback by Supermassive Black Holes?

open access: yesThe Astrophysical Journal Letters, 2023
The quenched fraction of satellite galaxies is aligned with the orientation of the halo’s central galaxy, such that on average, satellites form stars at a lower rate along the major axis of the central.

Satellites and haloes of dwarf galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mainly on bright primaries, our central galaxies span a wide range of stellar mass, 10^7.5 < M_*^pri/M_sun < 10^11, from dwarfs to central cluster galaxies.
