Properties of Galaxy Groups in the SDSS: I.-- The Dependence of Colour, Star Formation, and Morphology on Halo Mass [PDF]

open access: yes, 2005
Using a large galaxy group catalogue constructed from the SDSS, we investigate the correlation between various galaxy properties and halo mass. We split the population of galaxies in early types, late types, and intermediate types, based on their colour ...

The properties of fossil groups of galaxies [PDF]

open access: yesAstronomische 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 ...

High‐Performance Stretchable Gallium Battery for Wearable Electronics, Through Synthesis of Foam Electrodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Foam electrode synthesis, characterization, and application as a cathode in batteries. The demand for sustainable and stretchable thin‐film printed batteries for bioelectronics, wearables, and e‐textiles is rapidly increasing. Recently, we developed a fully 3D‐printed soft‐matter thin‐film Ga‐Ag2O battery with 3R characteristics: resilient to ...

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

open access: yesMonthly 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-

Quality of life in heart failure. The heart of the matter. A scientific statement of the Heart Failure Association and the European Association of Preventive Cardiology of the European Society of Cardiology

open access: yesEuropean Journal of Heart Failure, EarlyView.
For most patients with chronic, progressive illnesses, maintaining good quality of life (QoL), with preserved functional capacity, is just as crucial as prolonging survival. Patients with heart failure (HF) experience much worse QoL and effort intolerance than both the general population and people with other chronic conditions, since they present a ...

The galaxy of Coxeter groups

open access: yesJournal 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.

Baryonically Closed Galaxy Groups

open access: yesThe 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 ...

Baseline characteristics of contemporary trial participants with heart failure and reduced ejection fraction: The VICTOR trial

open access: yesEuropean Journal of Heart Failure, EarlyView.
Baseline characteristics for the vericiguat global study in participants with chronic heart failure (VICTOR) trial. ARNI, angiotensin receptor/neprilysin inhibitor; CRT, cardiac resynchronization therapy; eGFR, estimated glomerular filtration rate; GDMT, guideline‐directed medical therapy; HF, heart failure; HFrEF, heart failure with reduced ejection ...

Formation of the Dark Matter–Deficient S0 Galaxy NGC 4111 under the Tidal Interactions

open access: yesThe Astrophysical Journal Letters
We present high-sensitivity and large-scale atomic hydrogen (H i ) observations toward lenticular (S0) galaxy NGC 4111 using the Five-hundred-meter Aperture Spherical Radio Telescope.
