The dispersion in pulsar -ray efficiency
Daniel Íñiguez-Pascual, Daniele Viganò, Diego F. Torres
The observational efficiency of pulsars, defined as the ratio of the observationally derived isotropic-equivalent luminosity, , where is the average…
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…
Inflated hot Jupiters: Inferring average atmospheric velocity via Ohmic models coupled with internal dynamo evolution
Daniele Viganò, Soumya Sengupta, Clàudia Soriano-Guerrero +4
The inflated radii observed in hundreds of hot Jupiters (HJ) represent a long-standing open issue. In this study, we quantitatively investigate this phenomenon within the framework…
Non-ideal MHD simulations of hot Jupiter atmospheres
Clàudia Soriano-Guerrero, Daniele Viganò, Rosalba Perna +2
In Hot Jupiters (HJs), atmospherically induced magnetic fields are expected to play an important role in controlling the wind circulation and in determining their inflated radii. H…
Synchro-curvature description of γ-ray light curves and spectra of pulsars: concurrent fitting
Daniel Íñiguez-Pascual, Diego F. Torres, Daniele Viganò
We present a concurrent fitting of spectra and light curves of the whole population of detected gamma-ray pulsars. Using a synchro-curvature model we compare our theoretical output…
Synchro-curvature description of -ray light curves and spectra of pulsars: global properties
Daniel Íñiguez-Pascual, Diego F. Torres, Daniele Viganò
This work presents a methodological approach to generate realistic -ray light curves of pulsars, resembling reasonably well the observational ones observed by the Fermi-Large Ar…
The role of Ohmic dissipation of internal currents on Hot Jupiter radii
Taner Akgün, Clàudia Soriano-Guerrero, Albert Elias-López +3
The inflated radii observed in hundreds of Hot Jupiters represent a long-standing open issue. The observed correlation between radii and irradiation strength, and the occasional ex…
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…
A very young radio-loud magnetar
P. Esposito, N. Rea, A. Borghese +20
The magnetar Swift ,J1818.0-1607 was discovered in March 2020 when Swift detected a 9 ms hard X-ray burst and a long-lived outburst. Prompt X-ray observations revealed a spin perio…
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…
Simulated magnetic field expulsion in neutron star cores
J. G. Elfritz, J. A. Pons, N. Rea +2
The study of long-term evolution of neutron star (NS) magnetic fields is key to understanding the rich diversity of NS observations, and to unifying their nature despite the differ…
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…
Searching for small-scale diffuse emission around SGR 1806-20
D. Viganò, N. Rea, P. Esposito +6
Diffuse radio emission was detected around the soft gamma-ray repeater SGR 1806-20, after its 2004 powerful giant flare. We study the possible extended X-ray emission at small scal…
Creation of magnetic spots at the neutron star surface
U. Geppert, D. Viganò
According to the partially screened gap scenario, an efficient electron-positron pair creation, a general precondition of radio-pulsar activity, relies on the existence of magnetic…
A strongly magnetized pulsar within grasp of the Milky Way's supermassive black hole
N. Rea, P. Esposito, J. A. Pons +21
The center of our Galaxy hosts a supermassive black hole, Sagittarius (Sgr) A*. Young, massive stars within 0.5 pc of SgrA* are evidence of an episode of intense star formation nea…

N. Rea, G. L. Israel, J. A. Pons +20
We report on the long term X-ray monitoring of the outburst decay of the low magnetic field magnetar SGR 0418+5729, using all the available X-ray data obtained with RXTE, SWIFT, Ch…
Hall drift in the crust of neutron stars - necessary for radio pulsar activity?
U. Geppert, J. Gil, G. Melikidze +2
The radio pulsar models based on the existence of an inner accelerating gap located above the polar cap rely on the existence of a small scale, strong surface magnetic field .…
