Structure and Evolution of Regular Galaxies
, 2021 The Thesis is an attempt to combine data from three previously independent areas - the structure and kinematics of stellar populations of the Galaxy, photometric and dynamical models of galaxies, and models of the dynamical and physical evolution of galaxies. This synthesis was made with the goal to understand better the vast topic of the structure and

, 2005 Flexion is the significant third-order weak gravitational lensing effect responsible for the weakly skewed and arc-like appearance of lensed galaxies. Here we demonstrate how flexion measurements can be used to measure galaxy halo density profiles and ...

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry
Advanced Materials, EarlyView.Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

THE SHAPE OF GALAXY STRUCTURES
The Astrophysical Journal, 2009 An analysis is presented for a statistically complete sample of 547 galaxy structures with z ≤ 0.16, each containing at least 10 objects. The sample was divided according to structure richness, representing 10 richness classes, with the distribution of ellipticities differing among individual classes.

Galaxy structure searches by photometric redshifts in the CFHTLS [PDF]
, 2009 Context. Counting clusters is one of the methods to constrain cosmological parameters, but has been limited up to now both by the redshift range and by the relatively small sizes of the homogeneously surveyed areas. Aims.

Multiwavelength Observations of the Second Largest Known FR II Radio Galaxy, NVSS 2146+82 [PDF]
, 2000 We present multi-frequency VLA, multicolor CCD imaging, optical spectroscopy, and ROSAT HRI observations of the giant FR II radio galaxy NVSS 2146+82. This galaxy, which was discovered by the NRAO VLA Sky Survey (NVSS), has an angular extent of nearly 20'

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

Calibrating Nonparametric Morphological Indicators from JWST Images for Galaxies over 0.5 < z < 3
The Astrophysical JournalThe measurements of morphological indicators of galaxies are often influenced by a series of observational effects. In this study, we utilize a sample of 832 TNG50 simulated galaxies with log( M _* / M _⊙ )> 9 at 0.5 < z < 3 to investigate the ...
