A search for runaway stars in 12 Galactic supernova remnants

open access: yesAstronomische Nachrichten, Volume 342, Issue 3, Page 553-577, March 2021., 2021
Runaway stars can result from core‐collapse supernovae in multiple stellar systems. If the supernova disrupts the system, the companion is ejected with its former orbital velocity. A clear identification of a runaway star can yield the time and place of the explosion, as well as orbital parameters of the pre‐supernova binary system.

Measurements of the Crab Pulsar’s Giant Radio Pulse Amplitude Power-law Index Using Low-frequency Arecibo and Green Bank Telescope Observations

open access: yesThe Astrophysical Journal, 2023
We report two low-frequency measurements of the power-law index for the amplitudes of giant radio pulses from the Crab pulsar. The two observations were taken with the Arecibo and Green Bank radio telescopes at center frequencies of 327 MHz and 350 MHz ...

What Makes the Crab Pulsar Shine? [PDF]

open access: yesAIP Conference Proceedings, 2008
Our high time resolution observations of individual pulses from the Crab pulsar show that the main pulse and interpulse differ in temporal behavior, spectral behavior, polarization and dispersion. The main pulse properties are consistent with one current model of pulsar radio emission, namely, soliton collapse in strong plasma turbulence.

On the VHE Spectrum and Formation of the Teraelectronvolt Pulsed Emission of the Crab Pulsar

open access: yesGalaxies, 2022
In the present paper, a model for the pulsed γ-ray emission of the Crab pulsar from 0.01 GeV to 1 TeV in the context of synchrotron emission generated in the vicinity of a light cylinder is developed.

VERITAS observations of the Crab pulsar [PDF]

open access: yesAIP Conference Proceedings, 2012
The Crab pulsar has been widely studied across the electromagnetic spectrum from radio to gamma-ray energies. The exact nature of the emission processes taking place in the pulsar is a matter of broad debate. Above a few GeV the energy spectrum turns over suddenly.

INTEGRAL observation of the Crab pulsar [PDF]

open access: yesAdvances in Space Research, 2006
The paper presents the timing and spectral analysis of several observations of the Crab pulsar performed with INTEGRAL in the energy range 3-500 keV. All these observations, when summed together provide a high statistics data set which can be used for accurate phase resolved spectroscopy.

Super-giant pulses from the Crab pulsar: energy distribution and occurrence rate [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2019
We present statistical analysis of a fluence-limited sample of over 1100 giant pulses from the Crab pulsar, with fluence > 130 Jy ms at ∼1330 MHz. These were detected in ∼260 h of observation with the National Centre for Radio Astrophysics (NCRA) 15 m ...
