Peering at the outflow mechanisms in the transitional pulsar PSR J1023+0038: simultaneous VLT, XMM-Newton, and Swift high-time resolution observations
M. C. Baglio, F. Vincentelli, S. Campana +6
We report on a NIR, optical and X-ray campaign performed in 2017 with the XMM-Newton and Swift satellites and the VLT/HAWK-I instrument on the transitional MSP PSR J1023+0038. NIR…
Chandra Spectral and Timing Analysis of Sgr A*'s Brightest X-ray Flares
Daryl Haggard, Melania Nynka, Brayden Mon +17
We analyze the two brightest Chandra X-ray flares detected from Sagittarius A*, with peak luminosities more than 600 x and 245 x greater than the quiescent X-ray emission. The brig…
Detailed X-ray spectroscopy of the magnetar 1E 2259+586
D. Pizzocaro, A. Tiengo, S. Mereghetti +7
Magnetic field geometry is expected to play a fundamental role in magnetar activity. The discovery of a phase-variable absorption feature in the X-ray spectrum of SGR 0418+5729, in…
Long X-ray flares from the central source in RCW 103
P. Esposito, A. De Luca, R. Turolla +7
We observed the slowly revolving pulsar 1E 161348-5055 (1E 1613, spin period of 6.67 h) in the supernova remnant RCW 103 twice with XMM-Newton and once with the Very Large Telescop…
Pulsating in unison at optical and X-ray energies: simultaneous high-time resolution observations of the transitional millisecond pulsar PSR J1023+0038
A. Papitto, F. Ambrosino, L. Stella +22
PSR J1023+0038 is the first millisecond pulsar discovered to pulsate in the visible band; such a detection took place when the pulsar was surrounded by an accretion disk and also s…
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…
