Topological interfaces between universes and generalized families of 2d QFTs
Pinak Banerjee, Yuhan Gai, Alonso Perez-Lona +4
Two-dimensional quantum field theories with topological point operators decompose into universes. Just as fusion categories have played an important role in understanding non-inver…
The dark matter halo mass function in the cosmology at all times and over all scales -- from planetary to galaxy cluster masses
Haonan Zheng, Sownak Bose, Carlos S. Frenk +7
The dark matter halo mass function is one of the most fundamental predictions of structure formation theory and cosmological simulations. We present the full halo mass function in…
Distinguishing the nature of dark matter by mapping cosmic filaments from Lyman-alpha emission
Yizhou Liu, Liang Gao, Shihong Liao +3
The standard CDM cosmological model predicts that cosmic filaments are highly clumpy, whereas warm dark matter -- invoked to address small-scale challenges in CDM -- produces…
Particle loads for cosmological simulations with equal-mass dark matter and baryonic particles
Shihong Liao, Yizhou Liu, Haonan Zheng +5
Traditional cosmological hydrodynamical simulations usually assume equal-numbered but unequal-mass dark matter and baryonic particles, which can lead to spurious collisional heatin…
The impact of cosmic filaments on the abundance of satellite galaxies
Yuxi Meng, Haonan Zheng, Shihong Liao +9
The impact of cosmic web environments on galaxy properties plays a critical role in understanding galaxy formation. Using the state-of-the-art cosmological simulation IllustrisTNG,…
Ultra-diffuse galaxies in the EAGLE simulation
Haonan Zheng, Shihong Liao, Liang Gao +1
We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their propert…
Assembly History and Internal Structure of Cluster Cold Dark Matter Haloes

We use the Phoenix simulations to study the mass assembly history and internal structures of cluster dark matter haloes (). We…
Apostle--Auriga: Effects of stellar feedback subgrid models on the evolution of angular momentum in disc galaxies
Hang Yang, Shihong Liao, Azadeh Fattahi +7
Utilizing the Apostle--Auriga simulations, which start from the same zoom-in initial conditions of Local Group-like systems but run with different galaxy formation subgrid models a…
The influence of baryons on low-mass haloes

In this study of the `Resolving supermAssive Black hole Binaries In galacTic hydrodynamical Simulations' (RABBITS) series, we investigate the orbital evolution of supermassive blac…
The abundance of dark matter haloes down to Earth mass
Haonan Zheng, Sownak Bose, Carlos S. Frenk +5
We use the Voids-within-Voids-within-Voids (VVV) simulations, a suite of successive nested N-body simulations with extremely high resolution (denoted, from low to high resolution,…
The Timeless Timing Argument and the Mass of the Local Group
Till Sawala, Jorge Peñarrubia, Shihong Liao +1
The Timing Argument connects the motion of a two-body system to its mass in an expanding Universe with a finite age, under the assumption that it has evolved on a self-gravitating…
