Jet interactions with a giant molecular cloud in the Galactic centre and ejection of hypervelocity stars
Joseph Silk, Vincenzo Antonuccio-Delogu, Yohan Dubois +4
The hypervelocity OB stars in the Milky Way Galaxy were ejected from the central regions some 10-100 million years ago. We argue that these stars, {as well as many more abundant bo…
Lyman-alpha emission properties of simulated galaxies: interstellar medium structure and inclination effects
Anne Verhamme, Yohan Dubois, Jeremy Blaizot +5
[abridged] Aims. The aim of this paper is to assess the impact of the interstellar medium (ISM) physics on Lyman-alpha (Lya) radiation transfer and to quantify how galaxy orientati…
Blowing cold flows away: the impact of early AGN activity on the formation of a brightest cluster galaxy progenitor
Yohan Dubois, Christophe Pichon, Julien Devriendt +4
Supermassive black holes (BH) are powerful sources of energy that are already in place at very early epochs of the Universe (by z=6). Using hydrodynamical simulations of the format…
Cusp-core transformations in dwarf galaxies: observational predictions
Romain Teyssier, Andrew Pontzen, Yohan Dubois +1
The presence of a dark matter core in the central kiloparsec of many dwarf galaxies has been a long standing problem in galaxy formation theories based on the standard cold dark ma…
Constraining stellar assembly and AGN feedback at the peak epoch of star formation
Taysun Kimm, Sugata Kaviraj, Julien Devriendt +9
We study stellar assembly and feedback from active galactic nuclei (AGN) around the epoch of peak star formation (1<z<2), by comparing hydrodynamic simulations to rest-frame UV-opt…
Connecting the cosmic web to the spin of dark halos: implications for galaxy formation
Sandrine Codis, Christophe Pichon, Julien Devriendt +4
We investigate the alignment of the spin of dark matter halos relative (i) to the surrounding large-scale filamentary structure, and (ii) to the tidal tensor eigenvectors using the…
