Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP
is a space science mission designed to study fundamental physics under extreme conditions …

We report on the first observation of a radio-quiet active galactic nucleus (AGN) in polarized
X-rays: the Seyfert 1.9 galaxy MCG-05-23-16. This source was pointed at with the Imaging X …

Abstract In this White Paper we present the potential of the Enhanced X-ray Timing and
Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores …

Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short
timescales. However, the driver behind the X-ray variability is still poorly understood …

ABSTRACT MCG-5-23-16 is a Seyfert 1.9 galaxy at redshift z= 0.008 49. We analyse here
the X-ray spectra obtained with X-ray Multi-Mirror (XMM)-Newton and Nuclear Spectroscopic …

Pulsar timing arrays (PTAs) can detect disturbances in the fabric of spacetime on a galactic
scale by monitoring the arrival time of pulses from millisecond pulsars (MSPs). Recent …

Very steep reflection emissivity profiles in the inner part of accretion disks are commonly
found in the analysis of x-ray observations of black hole binaries and active galactic nuclei …

A fraction of the electromagnetic radiation emitted from the surface of a geometrically thin
and optically thick accretion disk of a black hole returns to the disk because of the strong …

The enhanced x-ray timing and polarimetry mission (eXTP) is a flagship observatory for x-
ray timing, spectroscopy and polarimetry developed by an international consortium. Thanks …
