Observation of a Rapidly Pulsating Radio Source
TLDR
In this article, the first report of a curious class of astronomical radio sources, distinguished by their rapid and extremely regular pulsations, was made by Hewish et al. They are now understood to be rapidly rotating, magnetized neutron stars, or pulsars.Abstract:
Unusual signals from pulsating radio sources have been recorded at the Mullard Radio Astronomy Observatory The radiation seems to come from local objects within the galaxy, and may be associated with oscillations of white dwarf or neutron stars 1968 saw the first report of a curious class of astronomical radio sources, distinguished by their rapid and extremely regular pulsations Hewish et al associated them with unusually stable oscillations in compact stars They are now understood to be rapidly rotating, magnetized neutron stars, or pulsarsread more

Quantum Black Holes in the Sky
TL;DR: In this article, the authors provide an overview of the strong motivations for why "quantum Black Holes" may be radically different from their classical counterparts in Einstein's General Relativity and discuss the observational signatures of quantum black holes, focusing on gravitational wave echoes as smoking guns for quantum horizons.

TL;DR: In this paper, the arrival times of the mean optical and radio pulses were determined using the tempo2 software package and the most accurate value for the optical-radio lag of 255±21 μs was presented.

Binary pulsars and relativistic gravitation
TL;DR: The first relativistic binary pulsar, SCR B1913+16, was discovered by Hulse and Taylor in 1974 and has been used to establish the most convincing evidence, so far, that the quadrupolar gravitational waves exist.

Noise analysis for X-ray navigation systems
TL;DR: In this article, the authors developed a general noise model for X-ray navigation instruments and used it to predict the performance of a typical XNAV system that could be used as the primary navigation resource on missions, including those beyond the orbit of Jupiter.

Interplanetary Scintillation of Small Diameter Radio Sources
TL;DR: In this article, the authors used the black-body equations to calculate the increased radiation appropriate to the observed brightness increase in the star over a 1,000 A.u. band-width at 5,400 A.U.

TL;DR: In this article, the authors discuss the association of solar cosmic rays with flare association, solar particle acceleration, recurrence and low energy solar particle events, and discuss the effects of solar particle particle acceleration.

Possible magnetospheric phenomena associated with neutron stars
TL;DR: In this paper, it was shown that the importance of the early cooling by emission of neutrinos from the Urca process has been underestimated in the foregoing investigations, and the calculations of Miss Tsuruta indicate that a neutron star will rapidly cool to 3 or 4 × 106 °K, but that after 105 years its surface temperature will still be about 2 × 106°K.
