Jurassic–Paleogene intraoceanic magmatic evolution of the Ankara Mélange, north-central Anatolia, Turkey
Jurassic–Paleogene interoceanic magmatic evolution the Ankara Melange north-central Anatolia Turkey
2015/1/6
Oceanic rocks in the Ankara Mélange along the Izmir–Ankara–Erzincan suture zone (IAESZ) in north-central Anatolia include locally coherent ophiolite complexes (~ 179 Ma and ~ 80̷...
The Cretaceous and Cenozoic tectonic evolution of Southeast Asia
Cretaceous Cenozoic tectonic evolution Southeast Asia
2015/1/6
Tectonic reconstructions of Southeast Asia have given rise to numerous controversies that include the accretionary history of Sundaland and the enigmatic tectonic origin of the proto-South China Sea. ...
Spatial models for monitoring the spatio-temporal evolution of ashes after fire – a case study of a burnt grassland in Lithuania
The thickness of the ash soil erosion unscheduled fire ash thickness measurement
2015/1/5
Ash thickness is a key variable in the protection of soil against erosion agents after planned and unplanned fires. Ash thickness measurements were conducted along two transects (flat and sloping area...
Bar-driven dark halo evolution: A resolution of the cusp-core controversy
theory dark matter
2014/12/26
Simulations predict that the dark matter halos of galaxies should have central cusps, while those inferred from observed galaxies do not have cusps. We demonstrate, using both linear perturbation theo...
Investigating the long-term evolution of galaxies: Noise, cuspy halos and bars
cuspy halos bars
2014/12/26
I review the arguments for the importance of halo structure in driving galaxy evolution and coupling a galaxy to its environment. We begin with a general discussion of the key dynamics and examples of...
A Deep Radio Survey of Abell 2125. II. Accelerated Galaxy Evolution during a Cluster-Cluster Merger
Abell galaxies
2014/12/24
Using our extensive radio, optical, near-IR, and X-ray imaging and spectroscopy, we consider the reason for the unusually large number of radio-detected galaxies, mostly found outside the cluster core...
The evolution of a stellar bar transforms not only the galactic disc, but also the host dark matter halo. We present high-resolution, fully self-consistent N-body simulations that clearly demonstrate ...
The bar-halo interaction - II. Secular evolution and the religion of N-body simulations
stellar dynamics dark matter
2014/12/23
This paper explores resonance-driven secular evolution between a bar and dark matter halo using N-body simulations. We make direct comparisons to our analytic theory to demonstrate the great difficult...
We present a theory for describing the evolution of a galaxy caused by stochastic events such as weak mergers, transient spiral structure, orbiting blobs, etc. This noise excites large-scale patterns ...
Using the theory describing the evolution of a galaxy halo due to stochastic fluctuations developed in the companion paper, we show that a halo quickly evolves toward the same self-similar profile, in...
Lynden-Bell & Kalnajs (1972) presented a useful formula for computing the long-range torque between spiral arms and the disk at large. The derivation uses second-order perturbation theory and assumes ...
Evolution of the Mass Function of the Galactic Globular Cluster System
general stellar dynamics
2014/12/23
In this work we investigate the evolution of the mass function of the Galactic globular cluster system (GCMF) taking into account the effects of stellar evolution, two-body relaxation, disk shocking a...
The Evolution of Galaxy Disks in Dense Environments - Lessons from Compact Galaxy Groups
evolution interactions
2014/12/23
Disk galaxies in compact galaxy groups exhibit a remarkable shortfall of neutral hydrogen compared to both isolated spirals and spirals in more loose groups, but the origin of this HI deficiency remai...
Galaxy evolution in Hickson compact groups: the role of ram-pressure stripping and strangulation
evolution interactions
2014/12/23
Galaxies in compact groups tend to be deficient in neutral hydrogen compared to isolated galaxies of similar optical properties. In order to investigate the role played by a hot intragroup medium (IGM...
We study the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution, exploring the physical consequences of external effects and examining evolutionary trends i...
