We present a uniform analysis of the ROSAT HRI and the ASCA GIS/SIS data for 79 distant clusters of galaxies in the redshift range 0.1 < z < 0.82 to study the global structures of the intracluster medium. We have constructed an X-ray catalog consisting of the largest sample of clusters in the redshift range for which pointed X-ray observations were carried out with both the observatories. We de...

ABSTRACT In the hierarchical scenario of structure formation, galaxy clusters are ultimate virialized products in mass and time. Hot baryons intracluster medium (ICM) cold galaxies inhabit a dark matter dominated halo. Internal processes, accretion, mergers can perturb equilibrium, which is established only at later times. However, cosmic time when thermalization effective still to be assessed....

We present J and K-band luminosity functions (LF) for the Group Evolution Multiwavelength Study (GEMS) sample of 60 nearby groups of galaxies, with photometry from the 2MASS survey. We find that, as seen in B and R-band photometry of a subsample of these groups in our earlier work, the LFs of the X-ray dim groups (LX < 10 erg s) show a depletion of galaxies of intermediate luminosity around MK ...

Although Ca transport in plants is highly complex, the overexpression of vacuolar Ca(2+) transporters in crops is a promising new technology to improve dietary Ca supplies through biofortification. Here, we sought to identify novel targets for increasing plant Ca accumulation using genetical and comparative genomics. Expression quantitative trait locus (eQTL) mapping to 1895 cis- and 8015 trans...

GIGANTEA (GI) was originally identified by a late-flowering mutant in Arabidopsis, but subsequently has been shown to act in circadian period determination, light inhibition of hypocotyl elongation, and responses to multiple abiotic stresses, including tolerance to high salt and cold (freezing) temperature. Genetic mapping and analysis of families of heterogeneous inbred lines showed that natur...

Generalist necrotrophic pathogens including Botrytis cinerea cause significant yield and financial losses on Brassica crops. However, there is little knowledge about the mechanisms underlying the complex interactions encoded by both host and pathogen genomes in this interaction. This potentially includes multiple layers of plant defense and pathogen virulence mechanisms that could complicate in...

The baryonic mass fraction (Ωb/Ωm) can be sensitively constrained using X-ray observations of galaxy clusters. In this paper, we compare the baryonic mass fraction inferred from measurements of the cosmic microwave background with the gas mass fractions (fgas) of a sample of 19 clusters taken from the recent literature. In systems cooler than 4 keV, fgas declines as the system temperature decre...

We examine the X-ray, optical, and radio properties for members clusters of a new supercluster discovered during SRG/eROSITA Performance Verification phase. In 140 deg2 eROSITA Final Equatorial Depth Survey (eFEDS) field we detect previously unknown consisting chain eight galaxy at z=0.36. The redshifts these are determined through HSC photometric measurements. X-ray morphological dynamical pro...

Abstract We report on the measurement of thermal Sunyaev–Zel’dovich (tSZ) effect in circumgalactic medium (CGM) 641,923 galaxies with M ⋆ = 10 9.8–11.3 ⊙ at z &lt; 0.5, pushing exploration tSZ to lower-mass compared those previous studies. cross-correlate galaxy catalog Wide-field Infrared Survey Explorer and SuperCOSMOS Compton- y maps derived from combined data Atacama Cosmology Telescope Pla...

The mean intracluster gas fraction of X–ray clusters within their hydrostatic regions is derived from recent observational compilations of David, Jones & Forman and White & Fabian. At radii encompassing a mean density 500 times the critical value, the individual sample bi-weight means are moderately (2.4σ) discrepant; revising binding masses with a virial relation calibrated by numerical simula...
