Summary Orchard fruits such as pear and apple are important for ensuring global food security and agricultural economy as they not only provide essential nutrients, but also support biodiversity and ecosystem services. Breeders, growers and plant researchers constantly study desirable tree morphological features and floral characteristics to ensure ...

We present an algorithm designed to identify galaxy (proto)clusters in wide-area photometric surveys by first selecting their dominant galaxy—i.e., the brightest cluster galaxy (BCG) or protoBCG—through the local stellar mass density traced by massive ...

Galaxy Superclusters Detected in the Modified PF-Catalog Using the FOF Method
The Modified Catalog of Galaxy Clusters and Groups (Panko & Flin 2006, PF), covering an area of 5000 square degrees in the southern sky, was used as the input for the search of galaxy superclusters.

Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

The shapes of brightest cluster galaxies
The mean isophotal axis ratios are computed for a complete sample of 119 brightest cluster galaxies (BCGs) in Abell clusters. The cumulative distribution function F(q) of axis ratios for the BCGs differs from F(q) for a sample of ordinary elliptical galaxies at only the P=0.14 probability level, as measured by a Kolmogorov Smirnov test.

STAR FORMATION ACTIVITY IN CLASH BRIGHTEST CLUSTER GALAXIES [PDF]
The CLASH X-ray selected sample of 20 galaxy clusters contains ten brightest cluster galaxies (BCGs) that exhibit significant ($>$5 $ $) extinction-corrected star formation rates (SFRs). Star formation activity is inferred from photometric estimates of UV and H$ $+[\ion{N}{2}] emission in knots and filaments detected in CLASH HST ACS and WFC3 ...

The Local Volume Complete Cluster Survey is an ongoing program to observe nearly a hundred low-redshift X-ray-luminous galaxy clusters (redshifts 0.03 < z < 0.12 and X-ray luminosities in the 0.1–2.4 keV band L _X500c > 10 ^44 erg s ^−1 ) with the Dark ...

Extended Radio Emission in the Perhipheral Regions of the Shapley Concentration Core
The Shapley Concentration (SC) is a galaxy supercluster (few tens of degrees) in the Local Universe (<z>∼0.048) which is currently undergoing cluster mergers and group accretion.

This article identified two novel soft coral species (Parasphaerasclera dimorpha sp. nov. and Paraminabea inflata sp. nov.) from urbanized South China Sea waters, distinct in morphology and genetics. Our study highlighted undocumented coral diversity in the hyper‐urbanized Greater Bay Area, emphasizing the need for cryptic species documentation in ...

KINEMATICS OF 13 BRIGHTEST CLUSTER GALAXIES
Velocity dispersion profiles and rotation curves have been determined for a sample of 13 brightest duster galaxies (BCGs) in order to study their internal stellar kinematics and investigate their relationship to ellipticals. We find that BCGs generally display velocity dispersion profiles with gradients similar to those found in normal bright ...
