Membership-linked issue specialization within the G77 in UN climate negotiations

Abstract The Group of 77 and China (G77) coordinates developing-country positions in negotiations under the United Nations Framework Convention on Climate Change (UNFCCC), while many members also participate through overlapping negotiating ...

Quenching factors for Na recoils as a function of Tl dopant concentrations in NaI(Tl) crystals

Abstract Thallium-doped sodium iodide (NaI(Tl)) scintillation detectors play an important role in the field of direct dark matter (DM) searches. The DAMA/LIBRA experiment stands out for its reported observation of an annually modulating DM-...

Where Galaxies Go to Die: The Environments of Massive Quiescent Galaxies at 3 < z < 5

At low redshift, massive quiescent galaxies (MQGs) are most frequently found in massive, rich galaxy clusters, but at high redshift the trend is less clear. Here, we present spectroscopic evidence of the effects of environment on the format...

Anti-de Sitter → de Sitter transition driven by Casimir forces and mitigating tensions in cosmological parameters

Over the last few years, low- and high-redshift observations set off tensions in the measurement of the present-day expansion rate H0 and in the determination of the amplitude of the matter clustering in the late Universe (parameterized by ...

An Investigation of Disk Thickness in M51 from Hα, Paα, and Mid-infrared Power Spectra

Power spectra (PS) of high-resolution images of M51 (NGC 5194) taken with the Hubble Space Telescope and the James Webb Space Telescope (JWST) have been examined for evidence of disk thickness in the form of a change in slope between large ...

WORKPLANS: Workshop on Planetary Nebula Observations

This workshop is the second of the WORKPLANS series, which we started in 2016. The main goal of WORKPLANS is to build up a network of planetary nebulae (PNe) experts to address the main open questions in the field of PNe research. The speci...

Nuclear structure and astrophysics

The nuclear structure in regions of the Segré chart which are of astrophysical importance is reviewed. The main emphasis is put on those nuclei that are relevant for stellar nucleosynthesis in fusion processes, and in slow neutron capture, ...

Physics, Astrophysics and Cosmology with Gravitational Waves

Gravitational wave detectors are already operating at interesting sensitivity levels, and they have an upgrade path that should result in secure detections by 2014. We review the physics of gravitational waves, how they interact with detect...

Dijet production in diffractive deep-inelastic scattering in next-to-next-to-leading order QCD

Abstract Hard processes in diffractive deep-inelastic scattering can be described by a factorisation into parton-level subprocesses and diffractive parton distributions. In this framework, cross sections for inclusive dijet production in di...

Control variates from Eulerian and Lagrangian perturbation theory: Application to the bispectrum

Control variates have seen recent interest as a powerful technique to reduce the variance of summary statistics measured from costly cosmological $N$-body simulations. Of particular interest are the class of control variates which are analy...

The Maximum Offsets of Binary Neutron Star Mergers from Host Galaxies

We analytically derive, and illustrate with a population synthesis model, the maximum offset of binary neutron star mergers ejected from their host galaxies. This approximate maximum offset is 300 kpc $\times \,{({v}_{{\rm{esc}}}/500\,{\rm{...

Erratum to: Search for resonant and nonresonant production of pairs of dijet resonances in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

Astronomy and Astrophysics

A parameter study is undertaken for steady symmetrical planar field-aligned MHD bow shock flows around a perfectly conducting cylinder.For sets of values of the inflow plasma β and Alfvénic Mach number (M A ) which allow for switch-on shock...

eLISA: Astrophysics and cosmology in the millihertz regime

This document introduces the exciting and fundamentally new science and astronomy that the European New Gravitational Wave Observatory (NGO) mission (derived from the previous LISA proposal) will deliver. The mission (which we will refer to...

Theoretical Physics and Astrophysics

V L Ginzberg (translated by D ter Haar) 1979 Oxford: Pergamon x + 457 pp price £25 (£10 paperback) The author views his work as a supplementary text devoted to particular aspects of theoretical physics applied to astrophysics, rather than a...

On the Variability of Functional Connectivity and Network Measures in Source-Reconstructed EEG Time-Series

The idea of estimating the statistical interdependence among (interacting) brain regions has motivated numerous researchers to investigate how the resulting connectivity patterns and networks may organize themselves under any conceivable sc...

Anatomy of a Spin: The Information-Theoretic Structure of Classical Spin Systems

Collective organization in matter plays a significant role in its expressed physical properties. Typically, it is detected via an order parameter, appropriately defined for each given system’s observed emergent patterns. Recent developments...

Design of Low-Density Parity-Check Code Pair for Joint Source-Channel Coding Systems Based on Graph Theory

In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as...

A search for $t\bar{t}$ resonances with the ATLAS detector in 2.05 fb−1 of proton-proton collisions at $\sqrt{s} = 7~\mathrm{TeV}$

Abstract A search for top quark pair resonances in final states containing at least one electron or muon has been performed with the ATLAS experiment at the CERN Large Hadron Collider. The search uses a data sample corresponding to an integ...
