Glitches in Southern Pulsars [PDF]

International Astronomical Union Colloquium, 2000
AbstractParkes timing observations of 31 mostly young pulsars over nearly nine years are described. A total of 29 glitches were detected, of which 19 are previously unreported. Twelve glitches were seen in PSR J1341–6220, making this the most frequently glitching pulsar known, and the largest known glitch was detected in PSR J1614–5047.

STING Agonists and How to Reach Their Full Potential in Cancer Immunotherapy

Advanced Science, EarlyView.
STING agonists show promise in preclinical studies in boosting an anti‐tumor response using the immune system. However, different limitations remain, and future research is needed to better understand how STING activation impacts the tumor microenvironment, identify effective combination strategies, and determine the best tumor types for STING agonist ...

Millisecond pulsar velocities [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
We present improved timing parameters for 13 millisecond pulsars (MSPs), including nine new proper motion measurements. These new proper motions bring to 23 the number of MSPs with measured transverse velocities. In light of these new results we present and compare the kinematic properties of MSPs with those of ordinary pulsars.

Decoding the Nature of Coherent Radio Emission in Pulsars I: Observational Constraints

Universe
Radio observations from normal pulsars indicate that the coherent radio emission is excited by curvature radiation from charge bunches. In this review, we provide a systematic description of the various observational constraints on the radio emission ...

An evolutionary model for pulsar-driven supernova remnants [PDF]

Astron.Astrophys.420:937-944,2004, 2003
We present a model of a pulsar wind nebula evolving inside its associated supernova remnant. The model uses a hydrodynamics code to simulate the evolution of this system when the pulsar has a high velocity. The simulation distinguishes four different stages of pulsar wind nebula evolution: the supersonic expansion stage, the reverse shock interaction ...

Isolated Neutron Stars as Science Validation for XMM2ATHENA: Ensuring Robust Data for Future X‐Ray Astronomy

Astronomische Nachrichten, EarlyView.
ABSTRACT The discovery of radio‐quiet, x‐ray thermally emitting isolated neutron stars (XINSs) in the ROSAT All‐Sky Survey revealed a previously overlooked component of the neutron star population. Advancements in x‐ray instrumentation and the availability of deep, wide‐area optical surveys now enable us to explore XINSs at fainter x‐ray fluxes and ...

POLAR GAP IN THE PULSAR FORCE-FREE MAGNETOSPHERE STRUCTURE

Radio Physics and Radio Astronomy, 2015
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 ...

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter

Astronomische Nachrichten, EarlyView.
ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.
