Predicting ionised gas emission in 3D with SKIRT. I. Framework and validation
Anand Utsav Kapoor, Maarten Baes, Aaron Smith +7
Emission lines from ionised gas are key diagnostics of star formation, metallicity, and ionisation conditions in galaxies. Interpreting spatially resolved observations from integra…
TODDLERS 2.0: Stellar feedback and observables across diverse IMFs, binary populations, and cloud environments
Anand Utsav Kapoor, Andrea Gebek, Maarten Baes +4
Modeling the feedback-driven evolution of star-forming regions and their multi-wavelength emission is essential for interpreting galaxy observations across cosmic time. TODDLERS co…
The role of density breaks in driving spiral structure in disc galaxies
Karl Fiteni, Sven De Rijcke, Victor P. Debattista +1
It is well established that stellar discs are destabilized by sharp features in their phase space, driving recurrent spiral modes. We explore the extent to which surface-density br…
The impact of primordial black holes on the stellar mass function of ultra-faint dwarf galaxies
Nicolas Esser, Sven De Rijcke, Peter Tinyakov
If primordial black holes constitute the dark matter, stars forming in dark-matter dominated environments with low velocity dispersions, such as ultra-faint dwarf galaxies, may cap…
A new astrophysical solution to the Too Big To Fail problem - Insights from the MoRIA simulations
Robbert Verbeke, Emmanouil Papastergis, Anastasia A. Ponomareva +2
We test whether advanced galaxy models and analysis techniques of simulations can alleviate the Too Big To Fail problem (TBTF) for late-type galaxies, which states that isolated dw…
Spiral eigenmodes triggered by grooves in the phase space of disc galaxies
Sven De Rijcke, Ilya Voulis
We use linear perturbation theory to investigate how a groove in the phase space of a disc galaxy changes the stellar disc's stability properties. Such a groove is a narrow trough…
How the first stars shaped the faintest gas-dominated dwarf galaxies
Robbert Verbeke, Bert Vandenbroucke, Sven De Rijcke
Low-mass dwarf galaxies are very sensitive test-beds for theories of cosmic structure formation since their weak gravitational fields allow the effects of the relevant physical pro…
G2C2 - IV: A novel approach to study the radial distributions of multiple populations in Galactic globular clusters
Joachim Vanderbeke, Roberto De Propris, Sven De Rijcke +4
We use the HB morphology of 48 Galactic GCs to study the radial distributions of the different stellar populations known to exist in globular clusters. Assuming that the (extremely…
Numerical simulations of dwarf galaxy merger trees
Annelies Cloet-Osselaer, Sven De Rijcke, Bert Vandenbroucke +3
We investigate the evolution of dwarf galaxies using N -body/SPH simulations that incorporate their formation histories through merger trees constructed using the ex- tended Press-…
Gaseous infall triggering starbursts in simulated dwarf galaxies
Robbert Verbeke, Sven De Rijcke, Mina Koleva +3
Using computer simulations, we explored gaseous infall as a possible explanation for the starburst phase in Blue Compact Dwarf galaxies. We simulate a cloud impact by merging a sph…
On the origin of bursts in blue compact dwarf galaxies: clues from kinematics and stellar populations
M. Koleva, S. De Rijcke, W. W. Zeilinger +3
Blue compact dwarf galaxies (BCDs) form stars at, for their sizes, extraordinarily high rates. In this paper, we study what triggers this starburst and what is the fate of the gala…
Simulations of the formation and evolution of isolated dwarf galaxies - II. Angular momentum as a second parameter
Joeri Schroyen, Sven De Rijcke, Sander Valcke +2
We show results based on a large suite of N-Body/SPH simulations of isolated, flat dwarf galaxies, both rotating and non-rotating. The main goal is to investigate possible mechanis…
Kelvin-Helmholtz instabilities in Smoothed Particle Hydrodynamics
Sander Valcke, Sven De Rijcke, Elke Roediger +1
In this paper we investigate whether Smoothed Particle Hydrodynamics (SPH), equipped with artificial conductivity, is able to capture the physics of density/energy discontinuities…
Peanut-shaped bulges in face-on disk galaxies
J. Mendez-Abreu, E. M. Corsini, V. P. Debattista +3
We present high resolution absorption-line spectroscopy of 3 face-on galaxies, NGC 98, NGC 600, and NGC 1703 with the aim of searching for box/peanut (B/P)-shaped bulges. These obs…
Internal Kinematics and Stellar Populations of the Poststarburst+AGN Galaxy SDSS J230743.41+152558.4
I. Chilingarian, S. De Rijcke, P. Buyle
We present the first 3D spectroscopic observations of a nearby HI detected poststarburst, or E+A, galaxy, SDSS J230743.41+152558.4, obtained with the VIMOS IFU spectrograph at ESO…
