COSMOLOGICAL MAGNETOHYDRODYNAMIC SIMULATIONS OF GALAXY CLUSTER RADIO RELICS: INSIGHTS AND WARNINGS FOR OBSERVATIONS [PDF]

, 2012
Non-thermal radio emission from cosmic-ray electrons in the vicinity of merging galaxy clusters is an important tracer of cluster merger activity, and is the result of complex physical processes that involve magnetic fields, particle acceleration, gas ...

JWST NIRCam Observations of the Globular Cluster Population of RXJ 2129.7+0005

The Astrophysical Journal
We present an analysis of the globular cluster (GC) population in the galaxy cluster RXJ 2129.7+0005 ( z = 0.234) based on JWST NIRCam imaging in three filters: F115W, F150W, and F200W.

Towards the first mean pressure profile estimate with the NIKA2 Sunyaev-Zeldovich Large Program [PDF]

EPJ Web of Conferences
High-resolution mapping of the hot gas in galaxy clusters is a key tool for cluster-based cosmological analyses. Taking advantage of the NIKA2 millimeter camera operated at the IRAM 30-m telescope, the NIKA2 SZ Large Program seeks to get a high ...

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, EarlyView.
What's New? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.

The Shape of the Chameleon Fifth-Force on the Mass Components of Galaxy Clusters

Universe
In the context of chameleon gravity, we present a semi-analytical solution of the chameleon field profile in an accurately modelled galaxy cluster’s mass components, namely the stellar mass of the Brightest Cluster Galaxy (BCG), the baryonic mass in ...

A New Algorithm for the Detection of Inter-cluster Galaxy Filaments using Galaxy Orientation Alignments

, 2005
We present a new algorithm to detect inter-cluster galaxy filaments based upon the assumption that the orientations of constituent galaxies along such filaments are non-isotropic.
