Galaxy harassment and the evolution of clusters of galaxies [PDF]
Nature, 1996 Disturbed spiral galaxies with high rates of star formation pervaded clusters of galaxies just a few billion years ago, but nearby clusters exclude spirals in favor of ellipticals. ``Galaxy harassment" (frequent high speed galaxy encounters) drives the morphological transformation of galaxies in clusters, provides fuel for quasars in subluminous hosts ...

Some Properties of Galaxy Structures
Open Astronomy, 2011 We analysed some properties of galaxies structures based on the PF catalog of galaxy structures (Panko & Flin 2006) and the Tully NBG catalog (Tully 1988).

Frontiers in Astronomy and Space Sciences, 2017 We use a semi-analytic model of galaxy formation and investigate how the mass of a seed black hole affect the scaling relation between black hole mass and bulge mass at z ~ 0.

Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions
Advanced Intelligent Systems, EarlyView.Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

The dust masses of powerful radio galaxies: clues to the triggering of their activity [PDF]
, 2014 We use deep Herschel Space Observatory observations of a 90% complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 < z < 0.7) to estimate the dust masses of their host galaxies and thereby investigate the triggering mechanisms for their ...

A New Dynamical Parameter for the Study of Sticky Orbits in a 3D Galactic Model
Open Astronomy, 2011 A 3D dynamical model is used to study the motion in the central parts of an elliptical galaxy, hosting a massive and dense nucleus. Our aim is to investigate the regular or chaotic character of the motion, with emphasis in the different chaotic ...

The Host Galaxies of Short GRBs as Probes of Their Progenitor Properties
Galaxies, 2019 We present and discuss the properties of host galaxies of short Gamma-ray Burst (SGRBs). In particular, we examine those observations that contribute to the understanding of the progenitor systems of these explosions. Most SGRB hosts are found to be star

The Relationship between Slope and Luminosity [PDF]
Kirkuk Journal of Science, 2010 In this study, a sample of galaxies has been adopted. It consists of 112 elliptical galaxies, among them were 56 dwarf elliptical galaxies, which belong to virgo cluster, 37 normal galaxies and 19 bright galaxies. Also, surface brightness profiles fitted
