Galaxy shape statistics in the effective field theory
Zvonimir Vlah, Nora Elisa Chisari, Fabian Schmidt
Intrinsic galaxy alignments yield an important contribution to the observed statistics of galaxy shapes. The general bias expansion for galaxy sizes and shapes in three dimensions…
The role of AGN on the structure, kinematics and evolution of ETGs in the Horizon simulations
M. S. Rosito, S. E. Pedrosa, P. B. Tissera +7
Feedback processes play a fundamental role in the regulation of the star formation (SF) activity in galaxies and, in particular, in the quenching of early-type galaxies (ETGs) as h…
Organised Randoms: Learning and correcting for systematic galaxy clustering patterns in KiDS using self-organising maps
Harry Johnston, Angus H. Wright, Benjamin Joachimi +10
We present a new method for the mitigation of observational systematic effects in angular galaxy clustering via corrective random galaxy catalogues. Real and synthetic galaxy data,…
Galaxy clusters as intrinsic alignment tracers: present and future
Casper J. G. Vedder, Nora Elisa Chisari
Galaxies and clusters embedded in the large-scale structure of the Universe are observed to align in preferential directions. Galaxy alignment has been established as a potential p…
Prospects for detection and application of the alignment of galaxies with the large-scale velocity field
Iris R. van Gemeren, Nora Elisa Chisari
Studies of intrinsic alignment effects mostly focus on the correlations between shapes of galaxies with each other, or with the underlying density field of the large scale structur…
Redshift and stellar mass dependence of intrinsic shapes of disc-dominated galaxies from COSMOS observations below
Kai Hoffmann, Clotilde Laigle, Nora Elisa Chisari +4
The high abundance of disc galaxies without a large central bulge challenges predictions of current hydrodynamic simulations of galaxy formation. We aim to shed light on the format…
