On the Origin of Gas-stripping of Galaxies in Group Environments

Jinsu Rhee, Christophe Pichon, Yohan Dubois +12

We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…

The dwarf stellar mass function in different environments and the lack of a generic missing dwarfs problem in ΛCDM

Ilin Lazar, Sugata Kaviraj, Garreth Martin +9

We combine deep photometric data in the COSMOS and XMM-LSS fields with high-resolution cosmological hydrodynamical simulations to explore two key questions: (1) how does the galaxy…

Distinguishing Ram Pressure from Tidal Interactions: the Size-Shape Difference (SSD) measure

Rory Smith, Stephanie Tonnesen, Katarina Kraljic +5

Context: In dense environments, disk galaxies can be subjected to tidal interactions with other galaxies and/or ram pressure stripping. Some morphological features are clearly asso…

Born to be Starless: Revisiting the Missing Satellite Problem

Seyoung Jeon, Sukyoung K. Yi, Emanuele Contini +6

The massive Local Group galaxies both host substantially fewer satellites than the subhalos expected from the cold dark matter paradigm, and the recent investigations have highligh…

Zippers and Twisters: Planes of Satellite Galaxies Emerge from Whirling and Shocking Gas Streams in the Cosmic Web

Janvi P. Madhani, Charlotte Welker, Sneha Nair +7

We investigate dwarf satellite systems around Milky Way analogs in the NewHorizon simulation. Using simple estimators limiting over-detection, we identify planes of satellites comp…

Large Scale Structure and the Cosmic Web

Rita Tojeiro, Katarina Kraljic

The formation and evolution of galaxies cannot be separated from large scale structure growth. Dark matter halos (and, therefore, galaxies) form and grow within the cosmic web - th…

Dissecting the formation of gas-versus-star counter-rotating galaxies from the NewHorizon simulation

S. Peirani, Y. Suto, S. Han +5

(Reduced)Using the NewHorizon simulation, we have studied ten gas-versus-star counter-rotating galaxies in field environments with a stellar mass of M*~[1-5]x10^10 Msun. For all of…

2D light distributions of dwarf galaxies -- key tests of the implementation of physical processes in simulations

Aaron Watkins, Garreth Martin, Sugata Kaviraj +5

Cosmological simulations provide much of the theoretical framework within which we interpret extragalactic observations. However, even if a given simulation reproduces the integrat…

A cosmic degeneracy story: structure formation with warm dark matter and scale-dependent primordial non-Gaussianities

Clément Stahl, Benoit Famaey, Rodrigo Ibata +2

It has been recently shown that cosmological models with scale-dependent primordial non-Gaussianities (sPNG) could provide a possible path to solve current cosmic tensions. Moreove…
