Spatial environment of polar-ring galaxies from the SDSS [PDF]

Astron. Lett., vol.43, 146-151, 2017; Pis'ma Astron.Zh., vol.43, 170-176, 2017, 2017
Based on SDSS data, we have considered the spatial environment of galaxies with extended polar rings. We used two approaches: estimating the projected distance to the nearest companion and counting the number of companions as a function of the distance to the galaxy.

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.

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.

Deep spectroscopy of nearby galaxy clusters: IV The quench of the star formation in galaxies in the infall region of Abell\ 85 [PDF]

, 2018
Our aim is to understand the role of the environment in the quenching of star formation of galaxies located in the infall cluster region of Abell 85 (A85). This is achieved by studying the post-starburst galaxy population as tracer of recent quenching.

Dependence of Galaxy Shape on Environment in the Sloan Digital Sky Survey [PDF]

Astrophys.J.634:1032-1042,2005, 2005
Using a sample of galaxies from the Sloan Digital Sky Survey (SDSS) Data Release 4, we study the trends relating surface brightness profile type and apparent axis ratio to the local galaxy environment. We use the SDSS parameter `fracDeV' to quantify the profile type.

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.

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 .

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 ...

No Evidence of Asymmetrically Enhanced Star Formation in Infalling Galaxies in UNIONS

The Astrophysical Journal
Ram pressure stripping is a well-known environmental quenching mechanism that removes gas from galaxies infalling into groups and clusters. In some extreme examples of ram pressure stripping, galaxies with extended gas tails show evidence of enhanced ...

The Evolution of the Cold Gas Fraction in Nearby Clusters’ Ram-pressure-stripped Galaxies

The Astrophysical Journal, 2023
Cluster galaxies are affected by the surrounding environment, which influences, in particular, their gas, stellar content, and morphology. In particular, the ram pressure exerted by the intracluster medium promotes the formation of multiphase tails of ...
