Some Issues on the Foundations of Modern Cosmology, Gravitation and Quantum Physics by Emilio Elizalde

“…After the first clear evidence of the recession—at very high speeds—of the spiral nebulae was announced by V.M. Slipher in 1914, as a result of his work started in 1912, it still took several decades to properly understand the phenomenon in terms of an expansion of the Universe. …”

Domesticating Light: Standards and Artisanal Knowledge in Early Astrophysics by Ordóñez Javier

“…Astrophysics was born in the nineteenth century as a “New Astronomy” (in the words of Samuel Langley, 1884), a knowledge built primarily by amateurs who explored deep space by studying the Sun, stars and nebulae. They were credible enough to interest physicists who did research on the properties of radiation and hence came to constitute a solid and recognised discipline. …”

Polarization of Intrabinary Shock Emission in Spider Pulsars by Andrew G. Sullivan, Roger W. Romani

“…Motivated by the new polarization capability of the Imaging X-ray Polarization Explorer and the confirmation of highly ordered magnetic fields in pulsar wind nebulae, we model the IBS polarization by employing two potential magnetic field configurations: toroidal magnetic fields imposed by the preshock pulsar wind, and tangential shock-generated fields that follow the postshock flow. …”

Practical Aspects of X-ray Imaging Polarimetry of Supernova Remnants and Other Extended Sources by Jacco Vink, Ping Zhou

“…This will be of particular interest for X-ray synchrotron emission from extended sources like young supernova remnants and pulsar wind nebulae. Here we report on employing a polarisation statistic that can be used to makes maps in the Stokes I, Q, and U parameters, a method that we expand by correcting for the energy-dependent instrumental modulation factor, using optimal weighting of the signal. …”
