We present new timing and spectral analyses of PSR J1412+7922 (Calvera) and PSR J1849−0001, which are only seen as pulsars in X-rays, based on observations conducted with the Neutron Star Interior Composition Explorer. We obtain updated and substantially improved pulse ephemerides compared to previous X-ray studies, as well as spectra that can be well fit by simple blackbodies and/or a power law. Our refined timing measurements enable deeper searches for pulsations at other wavelengths and…

NICER Study of Pulsed Thermal X-Rays from Calvera: A Neutron Star Born in the Galactic Halo?

Calvera (1RXS J141256.0+792204) is an isolated neutron star detected only through its thermal X-ray emission. Its location at high Galactic latitude (b = +37°) is unusual if Calvera is a relatively…

Phase transitions in neutron stars and their links to gravitational waves

The recent direct observation of gravitational wave event $GW170817$ and its $GRB170817A$ signal has opened up a new window to study neutron stars and heralds a new era of Astronomy referred to as…

Timing Six Energetic Rotation-powered X-Ray Pulsars, Including the Fast-spinning Young PSR J0058-7218 and Big Glitcher PSR J0537-6910

Measuring a pulsar’s rotational evolution is crucial to understanding the nature of the pulsar. Here, we provide updated timing models for the rotational evolution of six pulsars, five of which are…

Phase-resolved spectrum of the Crab pulsar from NICER

Context. Studies of the high-energy emission regions of rotation-powered pulsars are typically based on folded light curves (FLCs) and phase-resolved spectra (PRS). Aims. This work uses the NICER…

Searches for Gravitational Waves from Known Pulsars at Two Harmonics in 2015–2017 LIGO Data

We present a search for gravitational waves from 222 pulsars with rotation frequencies ≳10 Hz. We use advanced LIGO data from its first and second observing runs spanning 2015–2017, which provides…

Thermal luminosities of cooling neutron stars

Ages and thermal luminosities of neutron stars, inferred from observations, can be interpreted with the aid of the neutron star cooling theory to gain information on the properties of superdense…

Study of the morphology of the region surrounding eHWC J1850+001

Although at extreme energies (>50 TeV) W-ray sources generally have large angular separations from one another as observed on Earth, at lower energies in the galactic plane this is often not the…

Search for continuous gravitational waves from ten H.E.S.S. sources using a hidden Markov model

Isolated neutron stars are prime targets for continuous$-$wave (CW) searches by ground$-$based gravitational$-$wave interferometers. Results are presented from a CW search targeting ten pulsars. The…
