Furnishing the Galaxy with Pulsars

AIP Conference Proceedings, 2008
The majority of pulsar population synthesis studies performed to date have focused on isolated pulsar evolution. Those that have incorporated pulsar evolution within binary systems have tended to either treat binary evolution poorly of evolve the pulsar population in an ad-hoc manner.

Optimization of passivation in AlGaN/GaN heterostructure microwave transistor fabrication by ICP CVD [PDF]

Modern Electronic Materials, 2020
We have studied the effect of silicon nitride (SiN) dielectric passivating film deposition by inductively coupled plasma chemical vapor deposition (ICP CVD) on the parameters of AlGaN/GaN heterostructure high electron mobility transistors (HEMT).

On the Evidence for a Common-spectrum Process in the Search for the Nanohertz Gravitational-wave Background with the Parkes Pulsar Timing Array [PDF]

, 2021
A nanohertz-frequency stochastic gravitational-wave background can potentially be detected through the precise timing of an array of millisecond pulsars.

The FAST Galactic Plane Pulsar Snapshot survey: I. Project design and pulsar discoveries [PDF]

Research in Astronomy and Astrophysics, 2021
Discovery of pulsars is one of the main goals for large radio telescopes. The Five-hundred-meter Aperture Spherical radio Telescope (FAST), that incorporates an L-band 19-beam receiver with a system temperature of about 20 K, is the most sensitive radio ...

Common-red-signal analysis with 24-yr high-precision timing of the European Pulsar Timing Array: Inferences in the stochastic gravitational-wave background search [PDF]

, 2021
We present results from the search for a stochastic gravitational-wave background (GWB) as predicted by the theory of General Relativity using six radio millisecond pulsars from the Data Release 2 (DR2) of the European Pulsar Timing Array (EPTA) covering

Control of yellow photoluminescence in AlGaN/GaN heterostructures [PDF]

Modern Electronic Materials, 2019
Photoluminescence with the peak corresponding to yellow color of the visible spectrum (so-called yellow luminescence) originates from deep levels in the GaN buffer layers of heterostructures and depends on heterostructure growth conditions.

A Massive Pulsar in a Compact Relativistic Binary [PDF]

Science, 2013
Introduction Neutron stars with masses above 1.8 solar masses (M☉), possess extreme gravitational fields, which may give rise to phenomena outside general relativity.

Theoretical Study of Gamma-ray Pulsars [PDF]

Journal of Astronomy and Space Sciences, 2016
We use the non-stationary three dimensional two-layer outer gap model to explain gamma-ray emissions from a pulsar magnetosphere. We found out that for some pulsars like the Geminga pulsar, it was hard to explain emissions above a level of around 1 GeV.

PINT: A Modern Software Package for Pulsar Timing [PDF]

Astrophysical Journal, 2020
Over the past few decades, the measurement precision of some pulsar timing experiments has advanced from ∼10 μs to ∼10 ns, revealing many subtle phenomena.

Microlensing pulsars [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We investigate the possibilities that pulsars act as the lens in gravitational microlensing events towards the galactic bulge or a spiral arm. Our estimation is based on expectant survey and observations of FAST (Five hundred meter Aperture Spherical Telescope) and SKA (Square Kilometer Array), and two different models of pulsar distribution are used ...
