MRC B0319-454: Probing the large-scale structure with a giant radio galaxy

open access: yes, 2008
We present an investigation of the relationships between the radio properties of a giant radio galaxy MRC B0319-454 and the surrounding galaxy distribution with the aim of examining the influence of intergalactic gas and gravity associated with the large-

Thermochromic Gires‐Tournois Resonators with Tellurium for Battery Thermal Runaway Warning

open access: yesAdvanced Materials, EarlyView.
A thermochromic Gires‐Tournois (GT) resonator with a thin tellurium layer enables rapid, reversible, and untethered detection of battery surface temperature <80 °C. Exploiting tellurium's refractive index change driven by a thermally induced phase transition between solid and quasi‐liquid states, the GT resonator visualizes heat propagation, providing ...

Galaxy Evolution in Clusters [PDF]

open access: yes, 2019
In this thesis, we aim to further elucidate the phenomenon of galaxy evolution in the environment of galaxy clusters using the methodology of numerical simulations. For that, we have developed hydrodynamic models in which idealized gas-rich galaxies move within the ICM of idealized galaxy clusters, allowing us to probe in a detailed and controlled ...

The evolution of galaxy clustering [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1997
This paper investigates whether nonlinear gravitational instability can account for the clustering of galaxies on large and small scales, and for the evolution of clustering with epoch. No CDM-like spectrum is consistent with the shape of the observed nonlinear spectrum. Unbiased low-density models greatly overpredict the small-scale correlations; high-

A new measurement of the evolving near-infrared galaxy luminosity function out to z~4: a continuing challenge to theoretical models of galaxy formation

open access: yes, 2008
We present the most accurate measurement to date of cosmological evolution of the near-infrared galaxy luminosity function, from the local Universe out to z~4.

Synergistic Microcrack Engineering and Auxetic Metamaterials for Enhanced Sensitivity in Stretchable Strain Sensors

open access: yesAdvanced Materials Technologies, EarlyView.
A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.

ChemicalUniverseMachine. I. Uncovering the Cosmic Evolution of Metals in the Galaxy–Interstellar Medium–Circumgalactic Medium Ecosystem

open access: yesThe Astrophysical Journal
We present an empirical chemical evolution model that explains the distribution of metals in the interstellar medium (ISM) and the circumgalactic medium (CGM) of galaxies based on the U niverse M achine and N eutral U niverse M achine models in the ...

JWST/NIRSpec Measurements of Extremely Low Metallicities in High Equivalent Width Lyα Emitters

open access: yesThe Astrophysical Journal, 2023
Deep Very Large Telescope/MUSE optical integral field spectroscopy has recently revealed an abundant population of ultra-faint galaxies ( M _UV ≈ −15; 0.01 L _⋆ ) at z = 2.9−6.7 due to their strong Ly α emission with no detectable continuum.

Cosmological evolution of galaxies [PDF]

open access: yes, 2013
I review the subject of the cosmological evolution of galaxies, including different aspects of growth in disk galaxies, by focussing on the angular momentum problem, mergers, and their by-products. I discuss the alternative to merger-driven growth -- cold accretion and related issues.
