General-relativistic monopole magnetosphere of neutron stars: a pseudo-spectral discontinuous Galerkin approach

J. Pétri

The close vicinity of neutron stars remains poorly constrained by observations. Although plenty of data are available for the peculiar class of pulsars we are still unable to deduc…

The X-ray Flux Distribution of Sagittarius A* as Seen by Chandra

J. Neilsen, S. Markoff, M. A. Nowak +11

We present a statistical analysis of the X-ray flux distribution of Sgr A* from the Chandra X-ray Observatory's 3 Ms Sgr A* X-ray Visionary Project (XVP) in 2012. Our analysis indi…

Effect of geodetic precession on the evolution of pulsar high-energy pulse profiles as derived with the striped-wind model

J. Petri

Geodetic precession has been observed directly in the double-pulsar system PSR J0737-3039. Its rate has even been measured and agrees with predictions of general relativity. Very r…

A mass of less than 15 solar masses for the black hole in an ultraluminous X-ray source

C. Motch, M. W. Pakull, R. Soria +2

Most ultraluminous X-ray sources (ULXs) display a typical set of properties not seen in Galactic stellar-mass black holes (BHs): higher luminosity Lx > 3 10^39 erg/s, unusually sof…

Study of the X-ray activity of Sgr A* during the 2011 XMM-Newton campaign

Enmanuelle Mossoux, Nicolas Grosso, Frédéric H. Vincent +1

In Spring 2011 we observed Sgr A*, the supermassive black hole at the center of our Galaxy, with XMM-Newton with a total exposure of ~226 ks in coordination with the 1.3 mm VLBI. W…

On ultra-high energy cosmic ray acceleration at the termination shock of young pulsar winds

Martin Lemoine, Kumiko Kotera, Jérôme Pétri

Pulsar wind nebulae (PWNe) are outstanding accelerators in Nature, in the sense that they accelerate electrons up to the radiation reaction limit. Motivated by this observation, th…

Constraining the neutrino emission of gravitationally lensed Flat-Spectrum Radio Quasars with ANTARES data

S. Adrián-Martínez, A. Albert, M. André +134

This paper proposes to exploit gravitational lensing effects to improve the sensitivity of neutrino telescopes to the intrinsic neutrino emission of distant blazar populations. Thi…

Spectral State Transitions of the Ultraluminous X-ray Source IC 342 X-1

Hannah Marlowe, Philip Kaaret, Cornelia Lang +6

We observed the Ultraluminous X-ray Source IC 342 X-1 simultaneously in X-ray and radio with Chandra and the JVLA to investigate previously reported unresolved radio emission coinc…

A Search for Time Dependent Neutrino Emission from Microquasars with the ANTARES Telescope

S. Adrián-Martínez, A. Albert, M. André +143

Results are presented on a search for neutrino emission from a sample of six microquasars, based on the data collected by the ANTARES neutrino telescope between 2007 and 2010. By m…

Searches for clustering in the time integrated skymap of the ANTARES neutrino telescope

S. Adrián-Martínez, A. Albert, M. André +133

This paper reports a search for spatial clustering of the arrival directions of high energy muon neutrinos detected by the ANTARES neutrino telescope. An improved two-point correla…

XMM-Newton reveals a candidate period for the spin of the "Magnificent Seven" neutron star RX J1605.3+3249

Adriana M. Pires, Frank Haberl, Vyacheslav E. Zavlin +3

The group of thermally emitting isolated neutron stars (INSs) known as the "Magnificent Seven" (M7) is unique among the various neutron star populations. Crustal heating by means o…

General-relativistic electromagnetic fields around a slowly rotating neutron star: time-dependent pseudo-spectral simulations

J. Pétri

Pulsars are believed to loose their rotational kinetic energy primarily by a large amplitude low frequency electromagnetic wave which is eventually converted into particle creation…
