The anatomy of γ-ray pulsar light curves
(South African Institute of Physics, 2014)
To obtain constraints on the inclination and observer angles, <i>α</i> and <i>ζ</i>, of a <i>γ</i>-ray pulsar from its observed light curve (LC), we make use of geometric models detailing the position and extent of emission ...
Calibration of statistical methods used to constrain pulsar geometries via multiband light curve modelling
(SAIP, 2016)
Since its launch in 2008, the Fermi Large Area Telescope (LAT) has detected over
200 γ-ray pulsars above 100 MeV. This population of pulsars is characterised by a rich diversity
of light curve morphologies. Researchers ...
Very-high energy emission from pulsars
(SAIP, 2015)
The vast majority of pulsars detected by the Fermi Large Area Telescope (LAT)
display exponentially cutoff spectra with cutoffs falling in a narrow band around a few GeV.
Early spectral modelling predicted spectral cutoffs ...
Modelling the polarisation signatures detected from the first white dwarf pulsar AR Sco.
(Sissa Medialab, 2018)
Marsh et al. (2016) detected radio and optical pulsations from the binary system AR Scorpii (AR Sco). This system, with an orbital period of 3.55 h, is composed of a cool, low-mass star and a white dwarf with a spin period ...
Implementation of a goodness-of-fit test for finding optimal concurrent radio and γ-ray pulsar light curves
(SAIP, 2015)
Since the launch of the Fermi Large Area Telescope in 2008 the number of known
γ-ray pulsars has increased immensely to over 200, many of which are also visible in the
radio and X-ray bands. Seyffert et al. (2011) ...
What can we learn from phase alignment of γ-ray and radio pulsar light curves?
(SAIP, 2011)
The Fermi Large Area Telescope (LAT) has revolutionized high-energy (HE) astronomy, and is making enormous contributions particularly to γ-ray pulsar science. As a result of the many new pulsar discoveries, the γ-ray pulsar ...
High-energy pulsar light curves in an offset polar cap B-field geometry
(HEASA, 2016)
The light curves and spectral properties of more than 200
γ
-ray pulsars have been measured in
unsurpassed detail in the eight years since the launch of the hugely successful
Fermi
Large Area
Telescope (LAT)
γ
-ray ...
Multiwavelength analysis of four millisecond pulsars
(AIPC, 2011)
Radio timing observations of millisecond pulsars (MSPs) in support of Fermi LAT
observations of the gamma-ray sky enhance the sensitivity of high-energy pulsation searches. With
contemporaneous ephemerides we have detected ...
Modeling light curves of the phase-aligned gamma-ray millisecond pulsar subclass
(Fermi, 2011)
The gamma-ray population of millisecond pulsars (MSPs) detected by the Fermi Large Area Telescope
(LAT) has been steadily increasing. A number of the more recent detections, including PSR J0034−0534,
PSR J1939+2134 ...
Geometric modelling of radio and γ-ray light curves of 6 Fermi LAT pulsars
(Sissa Medialab, 2010)
The Fermi Large Area Telescope (LAT) has recently reported the detection of pulsed γ-rays
from 6 young pulsars (J0631+1036, J0659+1414, J0742−2822, J1420−6048, J1509−5850, and
J1718−3825), all exhibiting single-peaked ...
