Simulating winds in the Galactic centre: I. Supernova-driven multiphase outflows and HI cloud acceleration
Nicolas Peschken, Enrico M. Di Teodoro, Michał Hanasz +5
The centre of the Milky Way (MW) hosts powerful multiphase outflows, as evidenced by the Fermi and eROSITA bubbles, and by cold atomic hydrogen (HI) gas clouds detected up to a few…
Blueberry and Green Pea galaxies live in low density environments
Maitrayee Gupta, Jiří Svoboda, Konstantinos Kouroumpatzakis +3
Little is currently known about the large-scale environments of Green Pea (GP) and Blueberry (BB) galaxies, which are low-mass, compact systems with extreme specific star-formation…
A survey of molecular clouds in the Galactic center's outflow
Enrico M. Di Teodoro, Mark Heyer, Mark R. Krumholz +8
The nucleus of the Milky Way is known to drive a large-scale, multiphase galactic outflow, with gas phases ranging from the hot highly-ionized to the cold molecular component. In t…
Rhea-RT: Dynamical impact of Central Molecular Zone conditions on the properties of the interstellar medium and stellar feedback coupling
R. G. Tress, N. Brucy, P. Girichidis +22
The Central Molecular Zone (CMZ) is an extreme star formation environment, characterized by higher density, higher turbulence, stronger orbital shear, and stronger magnetic field s…
The phase structure of cosmic ray driven outflows in stream fed disc galaxies
Nicolas Peschken, Michał Hanasz, Thorsten Naab +2
Feeding with gas in streams is predicted to be an important galaxy growth mechanism. Using an idealised setup, we study the impact of stream feeding (with 10 M Myr$^{…
The angular momentum structure of cosmic ray driven galactic outflows triggered by stream accretion
Nicolas Peschken, Michał Hanasz, Thorsten Naab +2
We investigate the impact of gas accretion in streams on the evolution of disc galaxies, using magneto-hydrodynamic simulations including advection and anisotropic diffusion of cos…
Disc galaxies formed from major mergers in Illustris
Nicolas Peschken, Ewa L. Łokas, E. Athanassoula
We show how wet major mergers can create disc galaxies in a cosmological context, using the Illustris simulation. We select a sample of 38 disc galaxies having experienced a major…
Tidally induced bars in Illustris galaxies
Nicolas Peschken, Ewa L. Łokas
We study barred galaxies selected from the Illustris cosmological simulation, focusing on tidally induced bars formed from flyby interactions. To guarantee high enough resolution w…
Forming disc galaxies in major mergers: III. The effect of angular momentum on the radial density profiles of disc galaxies
N. Peschken, E. Athanassoula, S. A. Rodionov
We study the effect of angular momentum on the surface density profiles of disc galaxies, using high resolution simulations of major mergers whose remnants have downbending radial…
Forming disc galaxies in major mergers II. The central mass concentration problem and a comparison of GADGET3 with GIZMO
S. A. Rodionov, E. Athanassoula, N. Peschken
Context: In a series of papers, we study the major merger of two disk galaxies in order to establish whether or not such a merger can produce a disc galaxy. Aims: Our aim here is t…
Forming disk galaxies in wet major mergers. I. Three fiducial examples
E. Athanassoula, S. A. Rodionov, N. Peschken +1
Using three fiducial Nbody+SPH simulations, we follow the merging of two disk galaxies with a hot gaseous halo component each, and examine whether the merger remnant can be a spira…
