Impacts of the Metagalactic Ultraviolet Background on Circumgalactic Medium Absorption Systems
The Astrophysical JournalAmong the many different pieces of physics that go into simulations of the circumgalactic medium (CGM), the metagalactic ultraviolet background (UVB) plays a significant role in determining the ionization state of different metal species.

Hydrodynamical simulations of cluster formation with central AGN heating
, 2005 We analyse a hydrodynamical simulation model for the recurrent heating of the central intracluster medium (ICM) by active galactic nuclei (AGN). Besides the self-gravity of the dark matter and gas components, our approach includes the radiative cooling ...

Evolution of N/O ratios in galaxies from cosmological hydrodynamical simulations [PDF]
, 2018 We study the redshift evolution of the gas-phase O/H and N/O abundances, both (i) for individual ISM regions within single spatially-resolved galaxies and (ii) when dealing with average abundances in the whole ISM of many unresolved galaxies. We make use

Advanced Engineering Materials, EarlyView.The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Simulations of magnetized multiphase galactic disk regulated by supernovae explosions [PDF]
, 2014 What exactly controls star formation in the Galaxy remains controversial. In particular, the role of feedback and magnetic field are still partially understood.

The Astrophysical JournalThere has been increasing evidence of shadows from scattered light observations of outer protoplanetary disks (PPDs) cast from the (unresolved) disk inner region, while in the meantime these disks present substructures of various kinds in the ...

Compressing the Cosmological Information in One-dimensional Correlations of the Lyman-α Forest
The Astrophysical Journal, 2023 Observations of the Lyman- α forest from spectroscopic surveys such as the Baryon Oscillation Spectroscopic Survey or its extension, eBOSS, or the ongoing Dark Energy Spectroscopic Instrument (DESI) survey offer a unique window to study the growth of ...

Identifying the subtle signatures of feedback from distant AGN using ALMA observations and the EAGLE hydrodynamical simulations [PDF]
, 2017 We present sensitive 870 μm continuum measurements from our ALMA programmes of 114 X-ray selected active galactic nuclei (AGN) in the Chandra Deep Field-South and Cosmic Evolution Survey fields.

Ring galaxies in the EAGLE hydrodynamical simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L100N1504, a cubic cosmological volume of 100 cMpc on a side, to identify

Advanced Functional Materials, EarlyView.This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...
