Journal ArticleDOI
NIHAO - XI. Formation of ultra-diffuse galaxies by outflows
Arianna Di Cintio,Chris B. Brook,Aaron A. Dutton,Andrea V. Macciò,Andrea V. Macciò,Aura Obreja,Avishai Dekel +6 more
TL;DR: In this article, the authors used zoomin cosmological simulations from the Numerical Investigation of a Hundred Astrophysical Objects (NIHAO) project to show that ultra-diffuse galaxies (UDGs) form naturally in dwarf-sized haloes due to episodes of gas outflows associated with star formation.
Journal ArticleDOI
NIHAO XV: the environmental impact of the host galaxy on galactic satellite and field dwarf galaxies
Tobias Buck,Andrea V. Macciò,Andrea V. Macciò,Aaron A. Dutton,Aura Obreja,Jonas Frings,Jonas Frings +6 more
TL;DR: In this paper, the impact of the host on dwarf galaxy properties using four new Milky Way-like, ultra high-resolution simulations was studied, and the authors derived a metric to distinguish between galaxies harassed by the central object and unaffected ones.
Journal ArticleDOI
NIHAO IX: the role of gas inflows and outflows in driving the contraction and expansion of cold dark matter haloes
Aaron A. Dutton,Andrea V. Macciò,Andrea V. Macciò,Avishai Dekel,Liang Wang,G. S. Stinson,Aura Obreja,Arianna Di Cintio,Chris B. Brook,Tobias Buck,Xi Kang +10 more
TL;DR: In this article, the authors use similar to 100 cosmological galaxy formation 'zoom-in' simulations using the smoothed particle hydrodynamics code GASOLINE to study the effect of baryonic processes on the mass profiles of cold dark matter haloes.
Journal ArticleDOI
Inspiraling halo accretion mapped in Ly α emission around a z ∼ 3 quasar
Fabrizio Arrigoni Battaia,J. Xavier Prochaska,Joseph F. Hennawi,Joseph F. Hennawi,Aura Obreja,Tobias Buck,Sebastiano Cantalupo,Aaron A. Dutton,Andrea V. Macciò,Andrea V. Macciò +9 more
TL;DR: In this article, the authors reported the discovery of an enormous Ly alpha nebula (ELAN) around the quasar SDSS J102009.7 at z = 3.164, which was followedup with deeper MUSE observations.
Journal ArticleDOI
MaGICC baryon cycle: the enrichment history of simulated disc galaxies
Chris B. Brook,G. S. Stinson,Bradley Kenneth Gibson,Bradley Kenneth Gibson,S. Shen,Andrea V. Macciò,Aura Obreja,James Wadsley,Thomas R. Quinn +8 more
TL;DR: In this paper, the authors trace the baryonic cycle of infalling gas from the virial radius through to its eventual participation in the star formation process using cosmological galaxy formation simulations from the MaGICC (Making Galaxies in a Cosmological Context) project.
