The long-term enhanced brightness of the magnetar 1E 1547.0-5408
Francesco Coti Zelati, Alice Borghese, Nanda Rea +6
We present the evolution of the X-ray emission properties of the magnetar 1E 1547.0-5408 since February 2004 over a time period covering three outbursts. We analyzed new and archiv…
Spectral characterization of the non-thermal X-ray emission of gamma-ray pulsars
Francesco Coti Zelati, Diego F. Torres, Jian Li +1
We report on a detailed spectral characterization of the non-thermal X-ray emission for a large sample of gamma-ray pulsars in the second Fermi-LAT catalogue. We outline the criter…
QUBIC: using NbSi TESs with a bolometric interferometer to characterize the polarisation of the CMB
M. Piat, B. Bélier, L. Bergé +135
QUBIC (Q \& U Bolometric Interferometer for Cosmology) is an international ground-based experiment dedicated in the measurement of the polarized fluctuations of the Cosmic Microwav…
Wideband 67-116 GHz receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, V. Belitsky +43
ALMA has been operating since 2011, but has not yet been populated with the full suite of intended frequency bands. In particular, ALMA Band 2 (67-90 GHz) is the final band in the…
Magnetic, thermal and rotational evolution of isolated neutron stars
José A. Pons, Daniele Viganò
The strong magnetic field of neutron stars is intimately coupled to the observed temperature and spectral properties, as well as to the observed timing properties (distribution of…
A novel approach for the analysis of the geometry involved in determining light curves of pulsars
Daniele Viganò, Diego F. Torres
In this work, we introduce the use of the differential geometry Frenet-Serret equations to describe a magnetic line in a pulsar magnetosphere. These equations, which need to be sol…
Synchro-curvature modelling of the multi-frequency non-thermal emission of pulsars
Diego F. Torres, Daniele Vigano, Francesco Coti Zelati +1
We apply a synchro-curvature spectral emission model based on characterizing the dynamics of magnetospheric particles to fit the phase-average spectra of the most extended database…
Gradient sub-grid-scale model for relativistic MHD Large Eddy Simulations
Federico Carrasco, Daniele Viganò, Carlos Palenzuela
MHD turbulence is likely to play an important role in several astrophysical scenarios where the magnetic Reynolds is very large. Numerically, these cases can be studied efficiently…
Gravitational wave signatures of dark matter cores in binary neutron star mergers by using numerical simulations
Miguel Bezares, Daniele Viganò, Carlos Palenzuela
Recent detections by the gravitational wave facilities LIGO/Virgo have opened a window to study the internal structure of neutron stars through the gravitational waves emitted duri…
Extension of the sub-grid-scale gradient model for compressible magnetohydrodynamics turbulent instabilities
Daniele Viganò, Ricard Aguilera-Miret, Carlos Palenzuela
Performing accurate large eddy simulations in compressible, turbulent magnetohydrodynamics is more challenging than in non-magnetized fluids due to the complex interplay between ki…
Triggering magnetar outbursts in 3D force-free simulations
Federico Carrasco, Daniele Viganò, Carlos Palenzuela +1
In this letter, we present the first 3D force-free general relativity simulations of the magnetosphere dynamics related to the magnetar outburst/flare phenomenology. Starting from…
QUBIC: Exploring the primordial Universe with the Q\&U Bolometric Interferometer
Aniello Mennella, Peter Ade, Giorgio Amico +127
In this paper we describe QUBIC, an experiment that will observe the polarized microwave sky with a novel approach, which combines the sensitivity of state-of-the art bolometric de…
