INTEGRAL Observations of Magnetars [PDF]

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT The INTEGRAL satellite has collected a large amount of data on magnetars in our Galaxy, spanning more than 20 years starting from 2003. The large data set obtained with the IBIS/ISGRI instrument at energies above 20 keV allows us to study both the properties and long‐term evolution of their persistent hard X‐ray emission and the population ...

Magnetars [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2017
International audienceWhat is the origin of neutron star magnetic fields ? Although the fossil field hypothesis (i.e. the amplification of the neutron star progenitor field by flux conservation) would be the simplest mechanism, it seems unlikely to ...

No magnetars in ULXs [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
We consider the current observed ensemble of pulsing ultraluminous X-ray sources (PULXs). We show that all of their observed properties (luminosity, spin period, and spin-up rate) are consistent with emission from magnetic neutron stars with fields in ...

Wind braking of magnetars: To understand magnetars' multiwave radiation properties [PDF]

open access: yesAstronomische Nachrichten, 2014
Magnetars are proposed to be peculiar neutron stars powered by their super-strong magnetic field. Observationally, anomalous X-ray pulsars and soft gamma-ray repeaters are believed to be magnetar candidates.

Multipolar Electromagnetic Emission of Newborn Magnetars

open access: yesThe Astrophysical Journal
It is generally recognized that the electromagnetic multipolar emission from magnetars can be used to explain radiation from soft gamma repeaters or anomalous X-ray pulsars, but they have little impact on the spin-down of magnetars.

Searching for radio emission from radio quiet magnetars with MeerKAT

open access: yesAstronomy & Astrophysics
Context. Magnetars are neutron stars that occupy the extreme end of the neutron star population, with magnetic field strengths greater than 1012 G.

The Galactic Population of Magnetars: A Simulation-based Inference Study

open access: yesThe Astrophysical Journal
Population synthesis modeling of the observed dynamical and physical properties of a population is a highly effective method for constraining the underlying birth parameters and evolutionary tracks.

Numerical simulations of the tayler-spruit dynamo in proto-magnetars [PDF]

open access: yes, 2023
International audienceThe Tayler–Spruit dynamo is one of the most promising mechanisms proposed to explain angular momentum transport during stellar evolution. Its development in proto-neutron stars spun-up by supernova fallback has also been put forward

The Zoo of Isolated Neutron Stars

open access: yesUniverse, 2023
In this brief review, I summarize our basic knowledge about different types of isolated neutron stars. I discuss radio pulsars, central compact objects in supernova remnants, magnetars, nearby cooling neutron stars (also known as the magnificent seven ...

R-Process with Magnetized Nuclei at Dynamo-Explosive Supernovae and Neutron Star Mergers

open access: yesUniverse, 2021
Nucleosynthesis at latge magnetic induction levels relevant to core-collapse supernovae and neutron star mergers is considered. For respective magnetic fields of a strength up to ten teratesla, atomic nuclei exhibit a linear magnetic response due to the ...
