We collate the evidence for rotation-powered neutron stars that are visible as X-ray sources and not as radio pulsars. To date, 10 objects have been proposed, and one, Geminga, has been confirmed as a pulsar by the detection of 4.2-Hz pulsations. Several indicators have been used to support the proposition that the X-ray sources are isolated neutron stars, including high X-ray to optical/radio flux ratios, a constant X-ray flux and coincidence with a γ-ray source. Seven of the published neutron…

X-ray emission from the radio-quiet neutron star in puppis a
We show that X-rays detected with the ROSAT and ASCA observatories from the radio-quiet neutron star candidate RX J0822-4300 in the Puppis A supernova remnant can be interpreted as radiation from a
Isolated Neutron Stars: Accretors and Coolers
As many as 109 neutron stars populate the Galaxy, but only ≈103 are directly observed as pulsars or as accreting sources in X‐ray binaries. In principle, also the accretion of the interstellar medium
Emission spectra of fallback disks around young neutron stars
The nature of the energy source powering anomalous X-ray pulsars (AXPs) is uncertain. Proposed scenarios involve either an ultramagnetized neutron star or accretion onto a neutron star. We consider
Young Crab-like Pulsars and Luminous X-Ray Sources in Starbursts and Optically Dull Galaxies
Recent Chandra observations of nearby galaxies have revealed a number of ultraluminous X-ray sources (ULXs) with super-Eddington luminosities, away from the central regions of nonactive galaxies. The
Environments of Supernova Remnants Which Contain Different Types of Neutron Star
In the last few years new types of neutron stars having various degrees of activity have been identified. Among these are there dim radio quiet neutron stars and anomalous X-ray pulsars. In order to
Detection of radio emission from the gamma-ray pulsar J1732−3131 at 327 MHz
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

Most astronomers now accept that stars more massive than about 9 M⊙ explode as supernovae and leave stellar remnants, either neutron stars or black holes, with neutron stars being more prevalent.

TLDR
It is concluded that anomalous X-ray pulsars (AXPs) are young ( less, similar10,000 yr) objects and that they are produced in at least 5% of core-collapse supernovae.
Detection of 16 Gamma-Ray Pulsars Through Blind Frequency Searches Using the Fermi LAT
TLDR
The Fermi Large Area Telescope makes it possible to pinpoint neutron stars through their gamma-ray pulsations, enabling studies of emission mechanisms, population statistics, and the energetics of pulsar wind nebulae and supernova remnants.
Upper Limits on Periodic, Pulsed Radio Emission from the X-Ray Point Source in Cassiopeia A
The Chandra X-Ray Observatory recently discovered an X-ray point source near the center of Cassiopeia A, the youngest known Galactic supernova remnant. We have conducted a sensitive search for radio
