Magnetar Outburst Models with Cooling Simulations
D. De Grandis, N. Rea, K. Kovlakas +6
Magnetar outbursts are among the most noteworthy manifestations of magnetism in neutron stars. They are episodes in which the X-ray luminosity of a strongly magnetised neutron star…
On the Origin of Magnetar Fields: Chiral Magnetic Instability in Neutron Star Crusts
Clara Dehman, José A. Pons
We investigate the chiral magnetic instability in the crust of a neutron star as a potential mechanism for amplifying magnetic fields. This instability may become active when small…
3D code for MAgneto-Thermal evolution in Isolated Neutron Stars, MATINS: thermal evolution and lightcurves
Stefano Ascenzi, Daniele Viganò, Clara Dehman +3
The thermal evolution of isolated neutron stars is a key element in unraveling their internal structure and composition and establishing evolutionary connections among different ob…
Analyzing the Galactic pulsar distribution with machine learning
Michele Ronchi, Vanessa Graber, Alberto Garcia-Garcia +2
We explore the possibility of inferring the properties of the Galactic neutron star population through machine learning. In particular, in this paper we focus on their dynamical ch…
The X-ray outburst of the Galactic Center magnetar over six years of Chandra observations
N. Rea, F. Coti Zelati, D. Vigano' +16
The magnetar SGR J1745-2900 discovered at parsecs distance from the Milky Way central black hole, Sagittarius A*, represents the closest pulsar to a supermassive black hole ever de…
The multi-outburst activity of the magnetar in Westerlund I
A. Borghese, N. Rea, R. Turolla +17
After two major outbursts in 2006 and 2011, on 2017 May 16 the magnetar CXOU J164710.2-455216, hosted within the massive star cluster Westerlund I, emitted a short (20 ms) burst, w…
Gazing at the ultra-slow magnetar in RCW 103 with NuSTAR and Swift
A. Borghese, F. Coti Zelati, P. Esposito +6
We report on a new NuSTAR observation and on the ongoing Swift XRT monitoring campaign of the peculiar source 1E 161348-5055, located at the centre of the supernova remnant RCW 103…
Systematic study of magnetar outbursts
Francesco Coti Zelati, Nanda Rea, Jose Pons +2
We present the results of the systematic study of all magnetar outbursts observed to date, through a reanalysis of data acquired in about 1100 X-ray observations. We track the temp…
Chandra monitoring of the Galactic Centre magnetar SGR J1745-2900 during the initial 3.5 years of outburst decay
F. Coti Zelati, N. Rea, R. Turolla +15
We report on 3.5 years of Chandra monitoring of the Galactic Centre magnetar SGR J1745-2900 since its outburst onset in April 2013. The magnetar spin-down has shown at least two ep…
The discovery, monitoring and environment of SGR J1935+2154
G. L. Israel, P. Esposito, N. Rea +9
We report on the discovery of a new member of the magnetar class, SGR J1935+2154, and on its timing and spectral properties measured by an extensive observational campaign carried…
Constraining the GRB-magnetar model by means of the Galactic pulsar population
Nanda Rea, Miguel Gullon, Jose' A. Pons +4
A large fraction of Gamma Ray Bursts (GRBs) displays an X-ray plateau phase within <10^{5} s from the prompt emission, proposed to be powered by the spin-down energy of a rapidly s…
Population Synthesis of Isolated Neutron Stars with magneto-rotational evolution II: from radio-pulsars to magnetars
M. Gullón, J. A. Pons, J. A. Miralles +3
Population synthesis studies constitute a powerful method to reconstruct the birth distribution of periods and magnetic fields of the pulsar population. When this method is applied…
The X-ray outburst of the Galactic Centre magnetar SGR J1745-2900 during the first 1.5 year
F. Coti Zelati, N. Rea, A. Papitto +17
In 2013 April a new magnetar, SGR 1745-2900, was discovered as it entered an outburst, at only 2.4 arcsec angular distance from the supermassive black hole at the Centre of the Mil…
Magnetic fields in Neutron Stars
Daniele Viganò, Jose A. Pons, Juan A. Miralles +1
Isolated neutron stars show a diversity in timing and spectral properties, which has historically led to a classification in different sub-classes. The magnetic field plays a key r…
Spectral features in isolated neutron stars induced by inhomogeneous surface temperatures
Daniele Viganò, Rosalba Perna, Nanda Rea +1
The thermal X-ray spectra of several isolated neutron stars display deviations from a pure blackbody. The accurate physical interpretation of these spectral features bears profound…
Magnetic fields in neutron stars
Daniele Viganò
This work aims at studying how magnetic fields affect the observational properties and the long-term evolution of isolated neutron stars, which are the strongest magnets in the uni…
A new low-B magnetar: Swift J1822.3-1606
A. Camero-Arranz, N. Rea, G. L. Israel +16
We report on the long term X-ray monitoring with Swift, RXTE, Suzaku, Chandra, and XMM-Newton of the outburst of the newly discovered magnetar Swift J1822.3-1606 (SGR 182-1606), fr…
Modeling magnetar outbursts: Flux enhancements and the connection with short bursts and glitches
