The physical properties and evolution of Lyα emitting galaxies [PDF]

AIP Conference Proceedings, 2009
A significant fraction of high redshift starburst galaxies presents strong Ly alpha emission. Understanding the nature of these galaxies is important to assess the role they played in the early Universe and to shed light on the relation between the narrow band selected Lyalpha emitters and the Lyman break galaxies: are the Lyalpha emitters a subset of ...

The Hot and Energetic Universe:The evolution of galaxy groups and clusters [PDF]

, 2013
Major astrophysical questions related to the formation and evolution of structures, and more specifically of galaxy groups and clusters, will still be open in the coming decade and beyond: what is the interplay of galaxy, supermassive black hole, and ...

The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

‘A Sort of Armed Argument’: Ireland's Civil War of Words

History, EarlyView.
Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.

The effect of the environment on the evolution of galaxy colours [PDF]

, 2006
In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

Global Policy, EarlyView.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Merger-tree-based Galaxy Matching: A Comparative Study across Different Resolutions

The Astrophysical Journal
We introduce a novel halo/galaxy matching technique between two cosmological simulations with different resolutions, which utilizes the positions and masses of halos along their subhalo merger tree. With this tool, we conduct a study of resolution biases

Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Survey on Visualization of Information Diffusion over Networks

Computer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...
