Gamma-ray pulsar halos in the Galaxy
Pulsar halos are extended gamma-ray structures generated by electrons and positrons escaping from pulsar wind nebulae (PWNe), considered a new class of gamma-ray sources.

Pulsars’ signals reaching the atmosphere can be considered being stable under certain assumptions. In such a case the ionosphere remains the main factor distorting signal from the extraterrestrial sources, particularly if we observe them at long radio ...

A new nearby pulsar wind nebula overlapping the RX J0852.0-4622 supernova remnant [PDF]
Energetic pulsars can be embedded in a nebula of relativistic leptons which is powered by the dissipation of the rotational energy of the pulsar.

Variable Magellanic HMXB Sources versus Variable ULX Sources: Nothing to Brag about the ULX Sources
We carry out a meta-analysis of ultraluminous X-ray (ULX) sources that show large variabilities (by factors of >10) between their highest and lowest emission states in the X-ray energy range of 0.3–10 keV.

Spin Equilibrium of Rapidly Spinning Neutron Stars via Transient Accretion
The concept of spin equilibrium due to an interaction between the stellar magnetosphere and a thin, Keplerian accretion disk, and a well-known formula of the corresponding equilibrium spin frequency, provide a key understanding of spin evolution and the ...

With the great success of LTE(-A) outdoor, LTE-based small cell technology has become popular and is penetrating indoor enterprise environment, co-existing with WiFi networks, to provide better user experience or Quality-of-Experience (QoE). However, accurate estimation of LTE links is challenging and critical to continue providing QoE for many ...

Investigation of Accuracy of TOA and SNR of Radio Pulsar Signals for Vehicles Navigation
It is known that X-ray and gamma-ray pulsars can only be observed by spacecraft because signals from these pulsars are impossible to be detected on the Earth’s surface due to their strong absorption by the Earth’s atmosphere.

Pulsar Searches with the SKA [PDF]
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, already with SKA1, pulsar searches will discover enough pulsars to increase

POLAR GAP IN THE PULSAR FORCE-FREE MAGNETOSPHERE STRUCTURE
The stationary axisymmetric force-free magnetosphere of a pulsar is considered by accounting for the polar gap and current circuit. Adjustment of the vacuum polar gap and the closing current sheet with the force-free magnetosphere of a monopolar ...
