We study the formation of stellar bars using 145 simulations of disc galaxies embedded in live and static dark matter haloes. We use the exponential bar growth time-scale, [Formula: see text], to quantify how disc structure and kinematics r...
Origins and lifetimes of secular and tidal bars in simulated disc galaxies [0.03%]

Matthew Frosst et al.
We analyse 307 Milky Way-mass disc galaxies in the TNG50 cosmological simulation to study the formation and evolution of stellar bars through secular processes and tidal interactions. About 90 per cent of these galaxies form at least one ba...
Discs no more: the morphology of low-mass simulated galaxies in FIREbox [0.03%]

José A Benavides et al.
We study the morphology of hundreds of simulated central galaxies in the stellar mass range [Formula: see text] 107.5-1011 [Formula: see text] from the FIREbox cosmological volume. We demonstrate that FIREbox is able to predict a wide varie...
Tracing chemical depletion in evolved binaries hosting second-generation transition discs [0.03%]

Maksym Mohorian et al.
The mechanisms responsible for chemical depletion across diverse astrophysical environments are not yet fully understood. In this paper, we investigate chemical depletion in post-AGB/post-RGB binary stars hosting second-generation transitio...
Battle of the CH motions: aliphatic versus aromatic contributions to astronomical PAH emission and exploration of the aliphatic, aromatic, and ethynyl CH stretches [0.03%]
脂肪族与芳香族CH振动对天文学PAH发射的影响之争以及脂肪族、芳香族和乙炔基CH伸缩振动的探索

Vincent J Esposito et al.
Strong anharmonic coupling between vibrational states in polycyclic aromatic hydrocarbons (PAH) produces highly mixed vibrational transitions that challenge the current understanding of the nature of the astronomical mid-infrared PAH emissi...
AHKASH: a new Hybrid particle-in-cell code for simulations of astrophysical collisionless plasma [0.03%]

We introduce Astrophysical Hybrid-Kinetic simulations with the flash code ([Formula: see text]) - a new Hybrid particle-in-cell (PIC) code developed within the framework of the multiphysics code flash. The new code uses a second-order accur...

We investigate the environmental properties of the z = 0 radio galaxy population using the simba cosmological hydrodynamic simulation. We identify centrals and satellites from a population of high and low excitation radio galaxies (HERGs an...
Automation of finding strong gravitational lenses in the Kilo Degree Survey with U - DenseLens (DenseLens + Segmentation) [0.03%]
利用U-DenseLens（DenseLens+分割）自动化寻找千度survey中的强引力透镜现象

Bharath Chowdhary N et al.
In the context of upcoming large-scale surveys like Euclid, the necessity for the automation of strong lens detection is essential. While existing machine learning pipelines heavily rely on the classification probability (P), this study int...
An asymptotically correct implicit-explicit time integration scheme for finite volume radiation-hydrodynamics [0.03%]
有限体积辐射流体动力学的隐式显式时间积分方法的渐近正确性研究

Chong-Chong He
Numerical radiation-hydrodynamics (RHD) for non-relativistic flows is a challenging problem because it encompasses processes acting over a very broad range of time-scales, and where the relative importance of these processes often varies by...
Atomic diffusion and mixing in old stars - VIII. Chemical abundance variations in the globular cluster M4 (NGC 6121) [0.03%]
老恒星中的原子扩散和混合-VIII.M4（球状星团）(NGC 6121)的化学丰度变化

T Nordlander et al.
Variations in chemical abundances with evolutionary phase have been identified among stars in globular and open clusters with a wide range of metallicities. In the metal-poor clusters, these variations compare well with predictions from ste...
