Testing Rate Dependent corrections on timing mode EPIC-pn spectra of the accreting Neutron Star GX 13+1

F. Pintore, A. Sanna, T. di Salvo +6

When the EPIC-pn instrument on board XMM-Newton is operated in Timing mode, high count rates (>100 cts/s) of bright sources may affect the calibration of the energy scale, resultin…

An absence of fast radio bursts at intermediate galactic latitudes

E. Petroff, W. van Straten, S. Johnston +18

Fast radio bursts (FRBs) are an emerging class of bright, highly dispersed radio pulses. Recent work by Thornton et al. (2013) has revealed a population of FRBs in the High Time Re…

Geometrical constraints on the origin of timing signals from black holes

S. E. Motta, P. Casella, M. Henze +4

We present a systematic study of the orbital inclination effects on black-hole transients fast time-variability properties. We have considered all the black-hole binaries that have…

Broad iron emission line and kilohertz quasi-periodic oscillations in the neutron star system 4U 1636-53

Andrea Sanna, Mariano Mendez, Diego Altamirano +3

Both the broad iron (Fe) line and the frequency of the kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low-mass X-ray binaries (LMXBs) can potentially provide inde…

Chandra X-ray spectroscopy of a clear dip in GX 13+1

A. D'Aì, R. Iaria, T. Di Salvo +3

The source GX 13+1 is a persistent, bright Galactic X-ray binary hosting an accreting neutron star. It shows highly ionized absorption features, with a blueshift of 400 km s…
