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, ...

Comments on astrophysics and space physics

Radiative Processes in Astrophysics

Chapter 1 Fundamentals of Radiative Transfer 1.1 The Electromagnetic Spectrum Elementary Properties of Radiation 1.2 Radiative Flux Macroscopic Description of the Propagation of Radiation Flux from an Isotropic Source-The Inverse Square Law...

The Physics and Astrophysics of Neutron Stars

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...

Radiation Proceses in Astrophysics

The purpose of this book is twofold: to provide a brief, simple introduction to the theory of radiation and its application in astrophysics and to serve as a reference manual for researchers. The first part of the book consists of a discuss...

Accretion Power in Astrophysics

Radiative Processes in Astrophysics

George B Rybicki and Alan P Lightman 1980 Chichester: John Wiley xv + 382 pp price £19 The interaction of radiation with matter is a subject of fundamental importance in astrophysics. It is far from being an easy one to teach, not the least...

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...

Astronomy and Astrophysics

The distribution of interstellar extinction has been mapped over the whole sky, using all available spectral and photometric data.The colour excess distribution is modelled as a function of galactic latitude, longitude and distance within a...

Multi year changes of Aerosol Optical Depth in the monsoon region of the Indian Ocean since 1986 as seen in the AVHRR and TOMS data

Aerosol Optical Depth (AOD) data based on AVHRR and TOMS was analyzed to find out the changes in the Indian Ocean from 1981 to 2004. Four regions covering Indian Ocean north of 10° S were studied in detail. The results strongly sugge...

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{...

On the Temporal Variability of the Galactic Multi-TeV Interstellar Emissions

We use the GALPROP cosmic ray (CR) framework to model the Galactic CR distributions and associated nonthermal diffuse emissions up to PeV energies. We consider ensembles of discrete, finite lifetime CR sources, e.g., supernova remnants, for...

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...

Accretion Discs in Astrophysics

My life has been an interesting voyage. I became an astronomer because I could not imagine living on Earth and not trying to understand how the Universe works. My scientific career has revolved around observing the motions of stars within g...

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...

Genetic Algorithms in Astronomy and Astrophysics

This paper aims at demonstrating, through examples, the applicability of genetic algorithms to wide classes of problems encountered in astronomy and astrophysics. Genetic algorithms are heuristic search techniques that incorporate, in a com...
