Baryonic and dark matter distribution in cosmological simulations of spiral galaxies [PDF]

open access: yes, 2014
We study three cosmological hydrodynamical simulations of Milky Way(MW)-sized halos including a comparison with the dark matter(DM)-only counterparts. We find one of our simulated galaxies with interesting MW-like features. Thanks to a consistently tuned

The BAHAMAS project: Calibrated hydrodynamical simulations for large-scale structure cosmology [PDF]

open access: yes, 2016
The evolution of the large-scale distribution of matter is sensitive to a variety of fundamental parameters that characterise the dark matter, dark energy, and other aspects of our cosmological framework.

Radiation Hydrodynamical Simulations of the First Quasars [PDF]

open access: yesAstrophysical Journal, 2017
Supermassive black holes (SMBHs) are the central engines of luminous quasars and are found in most massive galaxies today. But the recent discoveries of ULAS J1120+0641, a 2 × 109 black hole (BH) at z = 7.1, and ULAS J1342+0928, a 8.0 × 108 BH at z = 7.5,

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Dynamical Consequence of Shadows Cast to the Outer Protoplanetary Disks. I. Two-dimensional Simulations

open access: yesThe Astrophysical Journal
There 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

open access: yesThe 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 ...

Light‐Responsive Enzyme‐Loaded Nanoparticles for Tunable Adhesion and Mechanical Wound Contraction

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a photoactivatable enzyme‐loaded mesoporous nanoparticle system (MPDA_PaTy) that enables light‐triggered tunable tissue adhesion and facilitates mechanical wound contraction. Controlled enzymatic crosslinking at tissue or hydrogel interfaces allows on‐demand adhesion.

The GHOSDT Simulations. II. Missing H2 in Simulations of a Self-regulated Interstellar Medium

open access: yesThe Astrophysical Journal
Observations in the Galaxy and nearby spirals have established that the H i -to-H _2 transition at solar metallicity occurs at gas weight of P _DE / k _B ≈ 10 ^4 K cm ^−3 , similar to solar neighborhood conditions.

Cosmology with the pairwise kinematic SZ effect: calibration and validation using hydrodynamical simulations [PDF]

open access: yes, 2017
We study the potential of the kinematic Sunyaev-Zel'dovich (kSZ) effect as a probe for cosmology, focusing on the pairwise method. The main challenge is disentangling the cosmologically interesting mean pairwise velocity from the cluster optical depth ...

Scaling Properties of Galaxy Groups

open access: yesUniverse, 2021
Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the gravitational and thermal evolution of the bulk of the cosmic matter ...
