text: We argue that measurements of X-ray polarization using the recently launched
Imaging X-ray Polarimetry Explorer will answer many open questions about magnetars
in particular the physical state of their surfaces, whether vacuum birefringence
exists, and the nature of the hard X-ray emission from these objects. We outline
the capabilities of the instrument, specific models and the results of simulations
for the magnetar 4U 0142+61.

text: "Due to the rich phenomenology and extreme magnetic conditions, magnetars
will be targets of great interest for the upcoming polarimetry space missions.
In particular, the Imaging X-ray Polarimetry Explorer (IXPE), recently launched
in December 2021, will operate in the 2–8 keV range. This will open a new window
to study the polarized, persistent X-ray emission from magnetars. In this talk,
I will present simulations of IXPE observations of magnetars using the IXPEObsSim
package. I will discuss future prospect to discriminate between different magnetar’s
emission mechanisms, as well as a potential detection of the signal of vacuum
birefringence using IXPE.\r\n\r\n"

text: Distant luminous Lyman-α emitters are excellent targets for detailed observations
of galaxies in the epoch of reionisation. Spatially resolved observations of these
galaxies allow us to simultaneously probe the emission from young stars, partially
ionised gas in the interstellar medium and to constrain the properties of the
surrounding hydrogen in the circumgalactic medium. We review recent results from
(spectroscopic) follow-up studies of the rest-frame UV, Lyman-α and [CII] emission
in luminous galaxies observed ∼500 Myr after the Big Bang with ALMA, HST/WFC3
and VLT/X-SHOOTER. These galaxies likely reside in early ionised bubbles and are
complex systems, consisting of multiple well separated and resolved components
where traces of metals are already present.

text: We propose an observational test for gravitationally recoiling supermassive
black holes in active galactic nuclei, based on a positive correlation between
the velocities of black holes relative to their host galaxies, |Δv|, and their
obscuring dust column densities, Σdust, both measured along the line of sight.
Our findings using a set of toy models implemented to a Monte Carlo simulation
imply that models of the galactic centre and of recoil dynamics can be tested
by future observations of the potential Σdust–|Δv| correlation. We have also found
that the fraction of obscured quasars decreases with |Δv|, for which the predicted
trend can be compared to the observed fraction of type II quasars, and can further
test combinations of models we may implement.
