Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation
Advanced Photonics Research, EarlyView.Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

Catalog of Visually Classified Galaxies in the Local ($z\sim0.01$) Universe [PDF]
, 2015 The morphological types of 5840 galaxies were classified by a visual inspection of color images using the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) to produce a morphology catalog of a representative sample of local galaxies with $z<0.01$. The sample galaxies are almost complete for galaxies brighter than $r_{pet}=17.77$.

Modeling Galaxy-Galaxy Weak Lensing with SDSS Groups [PDF]
MNRAS,394:1016-1030,2009, 2008 We use galaxy groups selected from the Sloan Digital Sky Survey (SDSS) together with mass models for individual groups to study the galaxy-galaxy lensing signals expected from galaxies of different luminosities and morphological types. We compare our model predictions with the observational results obtained from the SDSS by Mandelbaum et al. (2006) for

Genomic Insights into Post‐Domestication Expansion and Selection of Body Size in Ponies
Advanced Science, EarlyView.The authors’ research delves into the history of ponies by assembling a pony genome and integrating horse genomes. This unveils genetic connections between Asian and European pony breeds. Cis‐regulatory elements of key genes impacting body size are also identified.

Light Elements in the Universe
Frontiers in Astronomy and Space Sciences, 2021 Due to their production sites, as well as to how they are processed and destroyed in stars, the light elements are excellent tools to investigate a number of crucial issues in modern astrophysics: from stellar structure and non-standard processes at work

Are brightest halo galaxies central galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 It is generally assumed that the central galaxy in a dark matter halo, that is, the galaxy with the lowest specific potential energy, is also the brightest halo galaxy (BHG), and that it resides at rest at the centre of the dark matter potential well. This central galaxy paradigm (CGP) is an essential assumption made in various fields of astronomical ...

Photopatternable PEDOT:PSS Hydrogels for High‐Resolution Photolithography
Advanced Science, EarlyView.A photosensitive biphasic conducting polymer hydrogel (PB‐CH) is rationally designed with PEDOT:PSS as the conductive phase and a light‐sensitive matrix as the mechanical phase. Such a PB‐CH offers a unique combination of excellent conductivity (≈30 S cm⁻¹), robust mechanical performance (with stretchability up to 50%), and high photopatternability ...

Galaxy morphology in rich clusters: Implications for the formation and evolution of galaxies
, 1980 A study of the galaxy populations in 55 rich clusters is presented together with a discussion of the implications for the formation and/or evolution of different morphological types.

Modelling feedback from stars and black holes in galaxy mergers [PDF]
, 2004 We describe techniques for incorporating feedback from star formation and black hole (BH) accretion into simulations of isolated and merging galaxies. At present, the details of these processes cannot be resolved in simulations on galactic scales.
