Witnessing the Hierarchical Assembly of the Brightest Cluster Galaxy in a Cluster at z = 1.26 [PDF]

, 2002
We have obtained a new high-resolution K′-band image of the central region of the rich X-ray cluster RX J0848.9+4452 at z = 1.26. We found that the brightest cluster galaxy (BCG) in the cluster is clearly separated into two distinct objects.

Stellar formation in Brightest Cluster Galaxies [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractWe study the interplay between stellar population of the Brightest Cluster Galaxies (BCG) and cluster global properties. We use X-ray properties from Chandra, ROSAT and ASCA observations and BCGs spectra from SDSS-DR6. Using STARLIGHT we determined the star formation history of the BCGs and look for relations with the intra-cluster gas ...

Repeated Low‐Level Inflammatory Challenge Leads to Alterations in the TNF‐CXCL10 Signalling Pathway in Mouse Cerebral Endothelial Cells In Vitro

Journal of Neurochemistry, Volume 169, Issue 6, June 2025.
Intermittent, mild pro‐inflammatory systemic disease contributes to cerebrovascular pathology, however the mechanism of low‐level exposure causing injury remains unclear. Our RNA‐Seq analysis reveals continuous activation of tumour necrosis factor (TNF)‐Nuclear Factor kappa B (NF‐κB) signalling and multiple downstream inflammatory mediators in mouse ...

Coma cluster object populations down to M_R~-9.5 [PDF]

, 2007
This study follows a recent analysis of the galaxy luminosity functions and colour-magnitude red sequences in the Coma cluster (Adami et al. 2007). We analyze here the distribution of very faint galaxies and globular clusters in an east-west strip of ...

A triple nucleus in the brightest cluster galaxy in Abell 193 [PDF]

, 2003
We present a ground-based, near-infrared, K-band image and a Hubble Space Telescope (HST) WFPC2 image of the brightest cluster galaxy in Abell 193 (IC 1695). This object was selected as the central cluster galaxy using X-ray information.

Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1227-1235, May 2025.
Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...

Imaging the Thermal and Kinematic Sunyaev-Zel'dovich Effect Signals in a Sample of Ten Massive Galaxy Clusters: Constraints on Internal Velocity Structures and Bulk Velocities [PDF]

, 2019
We have imaged the Sunyaev-Zel'dovich (SZ) effect signals at 140 and 270 GHz towards ten galaxy clusters with Bolocam and AzTEC/ASTE. We also used Planck data to constrain the signal at large angular scales, Herschel-SPIRE images to subtract the ...

Dual and spatially resolved drought responses in the Arabidopsis leaf mesophyll revealed by single‐cell transcriptomics

New Phytologist, Volume 246, Issue 3, Page 840-858, May 2025.
Summary Drought stress imposes severe challenges on agriculture by impacting crop performance. Understanding drought responses in plants at a cellular level is a crucial first step toward engineering improved drought resilience. However, the molecular responses to drought are complex as they depend on multiple factors, including the severity of drought,

Early Science with the Karoo Array Telescope: a Mini-Halo Candidate in Galaxy Cluster Abell 3667

, 2014
Abell 3667 is among the most well-studied galaxy clusters in the Southern Hemisphere. It is known to host two giant radio relics and a head-tail radio galaxy as the brightest cluster galaxy.
