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 ...

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

Properties of intra-group stars and galaxies in galaxy groups: ‘normal’ versus ‘fossil’ groups [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
Cosmological LCDM simulations of 12 M_vir~10^14 Msun galaxy groups have been performed, invoking star formation, chemical evolution with non-instantaneous recycling, metallicity dependent radiative cooling, strong star-burst driven galactic super-winds and effects of a meta-galactic UV field. At z=0, intra-group light (IGL) fractions are found to be 12-

The properties of fossil groups of galaxies [PDF]

Astronomische Nachrichten, 2009
AbstractNumerical simulations as well as optical and X‐ray observations over the last few years have shown that poor groups of galaxies can evolve to what is called a fossil group. Dynamical friction as the driving process leads to the coalescence of individual galaxies in ordinary poor groups leaving behind nothing more than a central, massive ...

Integrated trajectories of systolic and diastolic function differentially associate with risk for heart failure with preserved and reduced ejection fraction and proteomic profiles

European Journal of Heart Failure, EarlyView.
Graphical overview of derivation and testing of multiparametric trajectories of cardiac function. This study identified six trajectories of LV systolic and diastolic function from mid‐ to late‐life. Predicted trajectory from single echocardiogram identified four trajectories at differential risk for HFpEF and HFrEF.

Baryonically Closed Galaxy Groups

The Astrophysical Journal, 2005
Elliptical galaxies and their groups having the largest L_x/L_B lie close to the locus in the L_x,L_B diagram expected for closed systems with baryon fractions equal to the cosmic mean value, f_b = 0.16. The estimated baryon fractions for several of these galaxies/groups are also close to 0.16 when the gas density is extrapolated to the virial radius ...

European Journal of Heart Failure consensus statement. Heart failure pharmacotherapy for patients with heart failure with reduced ejection fraction and concomitant atrial fibrillation: Review of evidence and call to action

European Journal of Heart Failure, EarlyView.
Heart failure (HF) and atrial fibrillation (AF) are major global health challenges with rising prevalence and significant morbidity, mortality, and healthcare burden. Despite advances in HF management, AF remains a critical comorbidity that worsens outcomes and requires ad hoc treatment strategies, increasing the risk of non‐adherence and side effects.

The galaxy of Coxeter groups

Journal of Algebra
In this paper we introduce the galaxy of Coxeter groups -- an infinite dimensional, locally finite, ranked simplicial complex which captures isomorphisms between Coxeter systems. In doing so, we would like to suggest a new framework to study the isomorphism problem for Coxeter groups.

New dwarf galaxy candidates in the Centaurus group

, 2015
Recent studies of the distribution and kinematics of the Milky Way and Andromeda satellite galaxy systems have confirmed the existence of coplanar, corotating structures of galaxies. In addition to the 'missing satellite problem', these structures pose a
