Self-interacting dark matter on small and large scales
SciPost Physics Proceedings, 2023 In the self-interacting dark matter paradigm (hereafter SIDM), dark matter (DM) is assumed to have non-gravitational interactions with itself. SIDM has been constrained by observations of galaxy clusters. More recently, measurements of large DM densities

The Astrophysical Journal, 2023 Using the IllustrisTNG simulation, we study the interaction of large-scale shocks with the circumgalactic medium (CGM) and interstellar medium (ISM) of star-forming (SF) satellite galaxies in galaxy clusters.

More Satellites of Spiral Galaxies [PDF]
The Astrophysical Journal, 1997 We present a revised and expanded catalog of satellite galaxies of a set of isolated spiral galaxies similar in luminosity to the Milky Way. This sample of 115 satellites, 69 of which were discovered in our multifiber redshift survey, is used to further probe the results obtained from the original sample (Zaritsky et al. 1993).

The colours of satellite galaxies in the Illustris simulation [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract Observationally, the fraction of blue satellite galaxies decreases steeply with host halo mass, and their radial distribution around central galaxies is significantly shallower in massive (M* ≥ 1011 M⊙) than in Milky Way-like systems.

A new spin on discs of satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We investigate the angular and kinematic distributions of satellite galaxies around a large sample of bright isolated primaries in the spectroscopic and photometric catalogues of the Sloan Digital Sky Survey (SDSS). We detect significant anisotropy in the spatial distribution of satellites.

DARK SATELLITES AND THE MORPHOLOGY OF DWARF GALAXIES [PDF]
The Astrophysical Journal, 2012 Submitted to ApJ Letters. 5 pages, 4 figures. A movie showing an encounter between a disky dwarf galaxy and a dark satellite can be found at http://www.astro.rug.nl/~ahelmi/dwarfs-morphologies ...

DWARF GALAXY CLUSTERING AND MISSING SATELLITES [PDF]
The Astrophysical Journal, 2009 At redshifts around 0.1 the CFHT Legacy Survey Deep fields contain some 6x10^4 galaxies spanning the mass range from 10^5 to 10^12 Msun. We measure the stellar mass dependence of the two point correlation using angular measurements to largely bypass the errors, approximately 0.02 in the median, of the photometric redshifts. Inverting the power-law fits

The origin of lopsided satellite galaxy distribution in galaxy pairs [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT It is well known that satellite galaxies are not isotropically distributed among their host galaxies as suggested by most interpretations of the Λ cold dark matter (ΛCDM) model. One type of anisotropy recently detected in the Sloan Digital Sky Survey (and seen when examining the distribution of satellites in the Local Group and ...
