EXTREMELY METAL-POOR GALAXIES: THE ENVIRONMENT [PDF]

The Astrophysical Journal, 2015
We have analyzed bibliographical observational data and theoretical predictions, in order to probe the environment in which extremely metal-poor dwarf galaxies (XMPs) reside. We have assessed the HI component and its relation to the optical galaxy, the cosmic web type (voids, sheets, filaments and knots), the overdensity parameter and analyzed the ...

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Insights into Galaxy Morphology and Star Formation: Unveiling Filamentary Structures around an Extreme Overdensity at z ∼ 1.5 Traced by [O ii] Emitters

The Astrophysical Journal Letters
We explore the morphological features and star formation activities of [O ii ] emitters in the COSMOS UltraDeep field at z ∼ 1.5 using JWST NIRCam data from the COSMOS-Web survey and Subaru Hyper Suprime-Cam.

On the filamentary environment of galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
The correlation between the large-scale distribution of galaxies and their spectroscopic properties at z=1.5 is investigated using the Horizon MareNostrum cosmological run. We have extracted a large sample of 10^5 galaxies from this large hydrodynamical simulation featuring standard galaxy formation physics.

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Environments around Quasars at z ∼ 3 Revealed by Wide-field Imaging with Subaru HSC and CFHT

The Astrophysical Journal
We examine the local density environments around 67 quasars at z ∼ 3 by combining the imaging data of Hyper Suprime-Cam Subaru Strategic Program and Canada–France–Hawaii Telescope Large Area U -band Deep Survey over about 20 deg ^2 .

ECO and RESOLVE: Galaxy Disk Growth in Environmental Context [PDF]

, 2015
We study the relationships between galaxy environments and galaxy properties related to disk (re)growth, considering two highly complete samples that are approximately baryonic mass limited into the high-mass dwarf galaxy regime, the Environmental ...

Galaxy evolution in the environment of ABCG 209 [PDF]

Astronomy & Astrophysics, 2004
We examine the environmental effects on the photometric properties of galaxies for the rich galaxy cluster ABCG 209 at z=0.209. We use archive CFHT optical imaging of a 42'x28' field centred on the cluster to produce a galaxy sample complete to B=25.0 and R=24.5.

Facile Bottom‐Up Assembly of Photonic Micropatterns via Surface‐Guided Colloidal Crystallization

Advanced Materials, EarlyView.
High‐resolution photonic micropatterns with vivid structural colors are fabricated through bottom‐up assembly, guided by surface‐dependent regioselective heterogeneous nucleation and crystal growth of colloidal particles. Full‐spectrum color tunability is achieved by controlling particle size and interparticle attraction, while in situ color mixing is ...
