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 ...

Business Strategy and the Environment, EarlyView.ABSTRACT As the urgency to address global crises such as climate change and inequality intensifies, the concept of regenerative development has emerged as a transformative approach going beyond sustainability to actively restore and enhance both ecological and social systems.

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

Galaxy groups in the presence of cosmological constant: Increasing the masses of groups
Physics Letters BThe boundaries of galaxy groups and clusters are defined by the interplay between the Newtonian attractive force and the decoupling from the local expansion of the Universe.

Journal of AlgebraIn 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.

DEEP CHANDRA OBSERVATIONS OF EDGES AND BUBBLES IN THE NGC 5846 GALAXY GROUP [PDF]
, 2011 We use a combined 120 ks Chandra exposure to analyze X-ray edges produced by non-hydrostatic gas motions (sloshing) from galaxy collisions, and cavities formed by active galactic nucleus (AGN) activity.
