Probing cosmology via the clustering of critical points
Junsup Shim, Christophe Pichon, Dmitri Pogosyan +5
Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, filament-void) of the density field define quasi-standard rulers that can be…
On the Origin of the Variety of Velocity Dispersion Profiles of Galaxies
San Han, Sukyoung K. Yi, Sree Oh +8
Observed and simulated galaxies exhibit a significant variation in their velocity dispersion profiles. We examine the inner and outer slopes of stellar velocity dispersion profiles…
The formation of cores in galaxies across cosmic time -- the existence of cores is not in tension with the LCDM paradigm
R. A. Jackson, S. Kaviraj, S. K. Yi +9
The `core-cusp' problem is considered a key challenge to the LCDM paradigm. Halos in dark matter only simulations exhibit `cuspy' profiles, where density continuously increases tow…
Emergence and cosmic evolution of the Kennicutt-Schmidt relation driven by interstellar turbulence
Katarina Kraljic, Florent Renaud, Yohan Dubois +12
The scaling relations between the gas content and star formation rate of galaxies provide useful insights into processes governing their formation and evolution. We investigate the…
How galaxy properties vary with filament proximity in the SIMBA simulations
Teodora-Elena Bulichi, Romeel Dave, Katarina Kraljic
We explore the dependence of global galaxy properties in the SIMBA simulation as a function of distance from filaments identified using DisPerSe. We exclude halos with mass $M_h>10…
BCG alignment with the Locations of Cluster Members and the Large Scale Structure out to 10 R
Rory Smith, Ho Seong Hwang, Katarina Kraljic +8
Using a sample of clusters, each with typically spectroscopically confirmed cluster members, we search for a signal of alignment between the Position Angle (PA) of…
On the Significance of the Thick Disks of Disk Galaxies
Sukyoung K. Yi, J. K. Jang, Julien Devriendt +8
Thick disks are a prevalent feature observed in numerous disk galaxies including our own Milky Way. Their significance has been reported to vary widely, ranging from a few to 100%…
Disk galaxies are self-similar: the universality of the HI-to-Halo mass ratio for isolated disks
Marie Korsaga, Benoit Famaey, Jonathan Freundlich +7
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.…
Hydrodynamical simulations of galaxy formation with non-Gaussian initial conditions
Clément Stahl, Yohan Dubois, Benoit Famaey +4
Collisionless simulations of structure formation with significant local primordial non-Gaussianities at Mpc scales have shown that a non-Gaussian tail favouring underdensities, wit…
HSC-CLAUDS survey: The star formation rate functions since z ~ 2 and comparison with hydrodynamical simulations
V. Picouet, S. Arnouts, E. Le Floch +16
Star formation rate functions (SFRFs) give an instantaneous view of the distribution of star formation rates (SFRs) in galaxies at different epochs. They are a complementary and mo…
