Intrinsic Alignments in IllustrisTNG and their implications for weak lensing: Tidal shearing and tidal torquing mechanisms put to the test

Jolanta Zjupa, Björn Malte Schäfer, Oliver Hahn

Accurate measurements of the cosmic shear signal require a separation of the true weak gravitational lensing signal from intrinsic shape correlations of galaxies. These `intrinsic…

A sea of tides: star formation and the central-satellite dichotomy in a continuum of tidal environments

Jolanta Zjupa, Aseem Paranjape, Oliver Hahn +1

The environment-dependent bimodality of the distribution of stellar mass () and specific star formation rate (sSFR) of galaxies, and its explanation in terms of the central…

Gas accretion and galactic fountain flows in the Auriga cosmological simulations: angular momentum and metal re-distribution

Robert J. J. Grand, Freeke van de Voort, Jolanta Zjupa +7

Using a set of 15 high-resolution magnetohydrodynamic cosmological simulations of Milky Way formation, we investigate the origin of the baryonic material found in stars at redshift…

Formation of a Malin 1 analogue in IllustrisTNG by stimulated accretion

Qirong Zhu, Dandan Xu, Massimo Gaspari +13

The galaxy Malin 1 contains the largest stellar disk known but the formation mechanism of this structure has been elusive. In this paper, we report a Malin 1 analogue in the 100 Mp…

The role of mergers and halo spin in shaping galaxy morphology

Vicente Rodriguez-Gomez, Laura V. Sales, Shy Genel +10

Mergers and the spin of the dark matter halo are factors traditionally believed to determine the morphology of galaxies within a CDM cosmology. We study this hypothesis by consi…

Angular momentum properties of haloes and their baryon content in the Illustris simulation

Jolanta Zjupa, Volker Springel

The angular momentum properties of virialised dark matter haloes have been measured with good statistics in collisionless N-body simulations, but an equally accurate analysis of th…
