Abstract Imaging X-ray Polarimetry Explorer (IXPE) is a Small Explorer mission by NASA
and Agenzia Spaziale Italiana, launched on 2021 December 9, dedicated to investigating X …

We report on the Imaging X-ray Polarimetry Explorer (IXPE) observation of the closest and X-
ray brightest Compton-thick active galactic nucleus (AGN), the Circinus galaxy. We find the …

Synchrotron emission from the shocked regions in supernova remnants provides, through its
polarization, crucial details about the magnetic field strength and orientation in these …

Supernova remnants are commonly considered to produce most of the Galactic cosmic rays
via diffusive shock acceleration. However, many questions regarding the physical conditions …

Young supernova remnants strongly modify the surrounding magnetic fields, which in turn
play an essential role in accelerating cosmic rays (CRs). The X-ray polarization …

Dust grains form in the clumpy ejecta of core-collapse supernovae where they are subject to
the reverse shock, which is able to disrupt the clumps and destroy the grains. Important dust …

In this study, we present the first-ever direct measurements of synchrotron-emitting
heliospheric traveling shocks, intercepted by the Parker Solar Probe (PSP) during its close …

We show here that highly polarized x-ray synchrotron radiation from young supernova
remnants (SNRs) can be modeled within the framework of diffusive shock acceleration …

The Imaging X-ray Polarimetry Explorer (IXPE) has confirmed that X-ray polarimetry is a
valuable tool in astronomy, providing critical insights into the emission processes and the …

In so-called spider pulsars, the X-ray band is dominated by intrabinary shock (IBS)
synchrotron emission. While the double-peaked X-ray light curves from these shocks have …
