Calculation of radar signals delay to second order in the frame of the General Relativity Theory

ACI Avances en Ciencias e Ingenierías, 2014
From the Schwarzschild metric, the light delay due to a gravitational field is calculated to second order approximation in the gravitational potential. We analize the contribution of the second order terms for strong gravitational fields as the generated

X-ray observations of the Large Magellanic Cloud pulsar PSR B0540-69 and its PWN

, 2008
PSR B0540-69 is a young pulsar in the Large Magellanic Cloud that has similar properties with respect to the Crab Pulsar, and is embedded in a Pulsar Wind Nebula.

Early phases of different types of isolated neutron star

, 2004
Two Galactic isolated strong X-ray pulsars seem to be in the densest environments compared to other types of Galactic pulsar. X-ray pulsar J1846-0258 can be in an early phase of anomalous X-ray pulsars and soft gamma repeaters if its average braking ...

Adaptive Filters Revisited - RFI Mitigation in pulsar observations

, 2004
Pulsar detection and timing experiments are applications where adaptive filters seem eminently suitable tools for radio-frequency-interference (RFI) mitigation.

Detection of radio emission from the gamma-ray pulsar J1732-3131 at 327 MHz

, 2017
Although originally discovered as a radio-quiet gamma-ray pulsar, J1732-3131 has exhibited intriguing detections at decameter wavelengths. We report an extensive follow-up of the pulsar at 327 MHz with the Ooty radio telescope.

Spin Tilts in the Double Pulsar Reveal Supernova Spin Angular-Momentum Production

, 2011
The system PSR J0737-3039 is the only binary pulsar known to consist of two radio pulsars (PSR J0737-3039 A and PSR J0737-3039 B). This unique configuration allows measurements of spin orientation for both pulsars: pulsar A's spin is tilted from the ...

Gamma-Ray Pulsar Visibility

, 2005
PSR J0437-4715 is a millisecond pulsar (MSP) thought to be ``pair formation starved'' (having limited pair cascades due to magnetic photon absorption).

PSR J1016-5857: a young radio pulsar with possible supernova remnant, X-ray, and gamma-ray associations

, 2001
We report the discovery of a young and energetic pulsar in the Parkes multibeam survey of the Galactic plane. PSR J1016-5857 has a rotation period of 107 ms and period derivative of 8e-14, implying a characteristic age of 21 kyr and spin-down luminosity ...

Search for a Correlation Between Radio Giant Pulses and VHE Photons of the Crab Pulsar

Acta Polytechnica, 2011
The Crab pulsar is a unique source of pulsar radio emission. Its regular pulse structure is visible over the entire electromagnetic spectrum from radio to GeV ranges.
