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 ...

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...

Intergalactic Wandering Stars in the Local Universe: Theoretical Predictions for Their Distance and Luminosity Distribution

Intergalactic wandering stars (IWSs) within 10 Mpc remain a poorly explored area of astronomy. Such stars, if they exist, are supposed to be wandering objects as they are not bound by the gravitational potential of any galaxy. We set out to...

For All Humankind: Peaceful, Ethical, Cooperative, and Curiosity‐Driven Space Science and Space Weather Research

Abstract Are we moving into a new reality where the next human stepping onto a different world will utter “That's one small step for me, a giant leap for my country”? Is further tightening Heliophysics and space weather research to military...

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 ...

Supersymmetric domain walls in 7D maximal gauged supergravity

Abstract We give a large class of supersymmetric domain walls in maximal seven-dimensional gauged supergravity with various types of gauge groups. Gaugings are described by components of the embedding tensor transforming in representations ...

How to Be a Copenhagenistic-QBistic Everettist

The measurement problem in quantum mechanics (QM) is related to the inability to include learning about the properties of a quantum system by an agent in the formalism of quantum theory. It includes questions about the physical processes be...

Smoothed Particle Hydrodynamics in Astrophysics

This review discusses smoothed particle hydrodynamics (SPH) in the astrophysical context, with a focus on inviscid gas dynamics. The particle-based SPH technique allows an intuitive and simple formulation of hydrodynamics that has excellent...

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...

Advances in Astrophysics

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to ascertain the nature of the heavenly bodies, rather than their positions or motions in space. Among the objects studied are the Sun, other s...

The KLT relation from the tree formula and permutohedron

Abstract In this paper, we generalize the Nguyen–Spradlin–Volovich–Wen (NSVW) tree formula from the MHV sector to any helicity sector. We find a close connection between the Permutohedron and the KLT relation, and construct a non-trivial ma...

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{...

Successive Partial Disruptions with Orbital Precession in a White Dwarf–Black Hole System for Repeating GRB 250702B

The peculiar gamma-ray burst GRB 250702B is the longest event ever observed, lasting about 1 day and exhibiting four prompt-emission flares of ∼100 s with irregular recurrence intervals of at least 1 hr. To explain this hierarchy of timesca...

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

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 Astrophysics

Graduate students and researchers in astrophysics and cosmology need a solid understanding of a wide range of physical processes. This clear and authoritative book has been designed to help them to develop the necessary toolkit of theory. T...

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...

Collisions and particle dynamics around black holes surrounded by PFDM in STVG

Abstract Testing dark matter effects on gravity around black holes in the framework of gravity theories through observational data is an essential task of relativistic astrophysical studies. In this work, we first obtain a new spacetime sol...

Impact of Higher Harmonics of Gravitational Radiation on the Population Inference of Binary Black Holes

Templates modeling just the dominant mode of gravitational radiation are generally sufficient for the unbiased parameter inference of near-equal-mass compact binary mergers. However, neglecting the subdominant modes can bias the inference i...

ZOTMPo–INAR(1) Process: Entropy and Modeling of Epidemiological Count Time Series Data

In this article, we propose a first-order integer-valued autoregressive (INAR(1)) model based on binomial thinning, in which the innovation sequence follows a zero–one–two-modified Poisson (ZOTMPo) distribution. The proposed model accommoda...
