The intergalactic gas in groups and clusters of galaxies bears the indelible stamp of galaxy formation. We present a comparison between observations and simple theoretical models indicating that radiative cooling governs the entropy scale that sets the core radius of the intracluster medium. Entropy measured at the radius 0.1r200 scales as T , in accord with cooling-threshold models for the reg...

Glucosinolates and their breakdown products have been recognized for their effects on plant defense, human health, flavor and taste of cruciferous vegetables. Despite this importance, little is known about the regulation of the biosynthesis and degradation in Brassica rapa. Here, the identification of quantitative trait loci (QTL) for glucosinolate accumulation in B. rapa leaves in two novel se...

We determine the contribution of stars in galaxies, intracluster stars, and the intracluster medium to the total baryon budget in nearby galaxy clusters and groups. We find that the baryon mass fraction (fb ≡ Ωb/Ωm) within r500 is constant for systems with M 500 between 6 × 10 13 M⊙ and 1 × 10 M⊙. Although fb is lower than the WMAP value, the shortfall is on the order of both the observational ...

ABSTRACT We investigate the cool gas absorption in galaxy clusters by cross-correlating Mg ii absorbers detected quasar spectra from data release 16 of Sloan Digital Sky Survey (SDSS) with identified Dark Energy Spectroscopic Instrument (DESI) survey. find significant covering fractions ($1\!-\!5\, \mathrm{per\,cent}$ within r500, depending on chosen redshift interval), ∼4–5 times higher than a...

Peneltitian ini bertujuan untuk menentukan desain angelbar bracket yang digunakan sebagai alat penghubung antara truk dan trailer, karena dalam instalasi Trailer SST74 pada Truk Scania R500 dibutuhkan fifth wheel JSK38 terpasang kerangka penghubung. Proses pemasangan diperlukan dudukan berupa antar keduanya. Metode perancangan pengembangan tersebut menggunakan Quality Function Deployment (QFD) ...

Many galaxy clusters host Megaparsec-scale radio halos, generated by ultrarelativistic electrons in the magnetized intracluster medium. Correlations between the synchrotron power of radio halos and the thermal properties of the hosting clusters were established in the last decade, including the connection between the presence of a halo and cluster mergers. The X-ray luminosity and redshift limi...

This is the second paper in a series of studies Coma cluster using SRG/eROSITA X-ray data obtained during calibration and performance verification phase mission. Here, we focus on region adjacent to radio source 1253+275 (radio relic, RR, hereafter). We show that surface brightness exhibits its steepest gradient at $\sim 79'$ ($\sim 2.2\,{\rm Mpc}\approx R_{200c}$), which almost co-spatial oute...

This study includes energy and exergy analysis if air ground source 
 heat pumps are used for residential heating in Kastamonu province. The lowest soil temperatures measured between December March 2000-2021 were taken into account. R134a, R407c, R410a R500 as refrigerants the process that will benefit from heating. In discussed, ambient temperature to be heated was chosen same each pump, ...

Everyone love children. They want them to be happy and prosperous, but poverty takes away their rights. Poverty even forces them to sell their daughters in exchange for money. The trio of poverty, sexual assaults and HIV are complimentary to one another.This paper is a selection of 5 cases who presented at Sinawe Center as victims of rape, where money has played a role in the delay in reporting...

The distribution of metals in groups of galaxies holds important information about the chemical enrichment history of the Universe. Here we present radial profiles of temperature and the abundance of iron and silicon of the hot intragroup medium for a sample of 15 nearby groups of galaxies observed by Chandra, selected for their regular X-ray morphology. All but one group display a cool core, t...
