A new nearby pulsar wind nebula overlapping the RX J0852.0-4622 supernova remnant [PDF]
, 2012 Energetic pulsars can be embedded in a nebula of relativistic leptons which is powered by the dissipation of the rotational energy of the pulsar.

Probing the properties of the pulsar wind via studying the dispersive effects in the pulses from the pulsar companion in a double neutron-star binary system [PDF]
, 2017 The velocity and density distribution of $e^\pm$ in the pulsar wind are crucial distinction among magnetosphere models, and contains key parameters determining the high energy emission of pulsar binaries.

Pulsar Searches with the SKA [PDF]
, 2017 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

Proceedings of the 11th ACM Conference on Emerging Networking Experiments and Technologies, 2015 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 ...

Variable Magellanic HMXB Sources versus Variable ULX Sources: Nothing to Brag about the ULX Sources
Galaxies, 2020 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
Galaxies, 2023 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 ...

Investigation of Accuracy of TOA and SNR of Radio Pulsar Signals for Vehicles Navigation
Sensors, 2023 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.
