Biermann battery as a source of astrophysical magnetic fields
Open Astronomy, 2021 A large number of galaxies have large-scale magnetic fields which are usually measured by the Faraday rotation of radio waves. Their origin is usually connected with the dynamo mechanism which is based on differential rotation of the interstellar medium ...

An algorithm for the direct reconstruction of the dark matter correlation function from weak lensing and galaxy clustering [PDF]
, 2010 The clustering of matter on cosmological scales is an essential probe for studying the physical origin and composition of our Universe. To date, most of the direct studies have focused on shear-shear weak lensing correlations, but it is also possible to ...

Galaxy subgroups in galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 Galaxies which fall into clusters as part of the same infall halo can retain correlations due to their shared origin. N-body simulations are used to study properties of such galaxy subgroups within clusters, including their richnesses and prevalence.

Joint galaxy–galaxy lensing and clustering constraints on galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We compare predictions for galaxy–galaxy lensing profiles and clustering from the Henriques et al. public version of the Munich semi-analytical model (SAM) of galaxy formation and the IllustrisTNG suite, primarily TNG300, with observations from KiDS + GAMA and SDSS-DR7 using four different selection functions for the lenses ...

FIRE-2 simulations: physics versus numerics in galaxy formation [PDF]
Monthly notices of the Royal Astronomical Society, 2017 The Feedback In Realistic Environments (FIRE) project explores feedback in cosmological galaxy formation simulations. Previous FIRE simulations used an identical source code (“FIRE-1”) for consistency.

The 6dF Galaxy Survey: baryon acoustic oscillations and the local Hubble constant [PDF]
, 2011 We analyse the large-scale correlation function of the 6dF Galaxy Survey (6dFGS) and detect a baryon acoustic oscillation (BAO) signal at 105h −1 Mpc. The 6dFGS BAO detection allows us to constrain the distance–redshift relation at zeff = 0.106.
