The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8

The Astrophysical Journal
We present results from a Keck/DEIMOS survey to study satellite quenching in group environments at z  ~ 0.8 within the Extended Groth Strip (EGS). We target 11 groups in the EGS with extended X-ray emission. We obtain high-quality spectroscopic redshifts

The radial structure of galaxy groups and clusters [PDF]

, 2003
Simple self-consistent models of galaxy groups and clusters are tested against the results of high-resolution adiabatic gasdynamical simulations. We investigate two models based on the existence of a 'universal' dark matter density profile and two ...

Mass-segregation trends in SDSS galaxy groups. [PDF]

, 2014
It has been shown that galaxy properties depend strongly on their host environment. In order to understand the relevant physical processes driving galaxy evolution it is important to study the observed properties of galaxies in different environments ...

Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

Batteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)

maggie: Models and Algorithms for Galaxy Groups, Interlopers and Environment [PDF]

, 2014
Redshift distortions make it notoriously difficult to recover real-space galaxy groups from redshift space data. We make use of the previously measured universal distribution of halo interlopers in projected phase space, which we combine with our ...

Enhancing Wholemeal Bread Shelf Life Using Optimized Mixtures of Cinnamon, Clove, and Bay Leaf Essential Oils

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study evaluated the preservative potential of essential oils (EOs) in bakery products by identifying fungal contaminants in bread, testing the in vitro antifungal activity of a mixture of cinnamon, clove, and bay leaf EOs, and assessing their effectiveness in extending shelf life. Fungal identification revealed the presence of Penicillium,

The origin of redshift asymmetries: How LambdaCDM explains anomalous redshift

, 2008
Several authors have found a statistically significant excess of galaxies with higher redshifts relative to the group centre, so-called discordant redshifts, in particular in groups where the brightest galaxy, identified in apparent magnitudes, is a ...

SARCS strong-lensing galaxy groups - II. Mass-concentration relation and strong-lensing bias [PDF]

, 2014
Our work is based on the stacked weak-lensing analysis of a sample of 80 strong-lensing galaxy groups. Our main results are the following: (i) the lensing signal does not allow us to firmly reject a simple singular isothermal sphere mass distribution ...

Early in‐hospital treatment of acute heart failure. Part 2 of the international expert opinion series on AHF management

ESC Heart Failure, EarlyView.
This state‐of‐the‐art review outlines a practical, evidence‐based framework for early acute heart failure management to address critical gaps in current guidance and improve early treatment outcomes. Key components include early identification of co‐existing conditions, bedside haemodynamic profiling, a structured diagnostic approach incorporating both
