description: We request MAGIC observations to provide sensitive VHE coverage for the multi-instrument campaigns in 2019-2020. These MAGIC observations are needed to characterise with accuracy the high-energy bump and its temporal evolution with simultaneous coverage for the low-energy bump comma  and will play an uniquely important role in the investigation of several important scientific questions comma  like the processes generating the flux variability comma  as well as to address whether the blazar emission is produced in a single or in multiple zones. These multi-year VHE data comma  together with its related MW data openParwhich includes XMM observations for three nights in Cycle 14closePar comma  will become one of the MAGIC legacy products that will be used by many scientists inside-outside our collaboration.

description: We recently published evidence for a steep decline in chromospheric ultraviolet emission compared with coronal X-ray emission for mid-to-late M dwarfs. Very late M dwarfs appear to be underluminous in the ultraviolet by two orders of magnitude. If confirmed comma  this chromospheric decline will have profound implications for the habitability of exoplanet systems similar to TRAPPIST-1. The chromospheric decline may also point to a change in stellar dynamo mechanism at the fully convective boundary. We propose XMM-Newton and HST observations of three very late M dwarfs in order to test that the chromospheric decline is a common feature of the class.

description: We propose to conduct the first hard X-ray study of I Zwicky 1 openParI Zw 1closePar comma  a unique AGN that will yield great insight into the physical processes associated with accretion and the extreme environments around supermassive black holes. Rapid variability is seen in the X-ray emission as the corona evolves as well as complex comma  variable absorption from outflows. I Zw 1 is the first AGN in which there is evidence for distinct structures within the corona comma  including a core akin to the base of a jet. We propose to observe I Zw 1 for 250ks using NuSTAR comma  130ks simultaneous with XMM-Newton. This will yield the most detailed comma  dynamic picture of how the corona is structured and how it evolves comma  transforming our understanding of how the corona and accretion disc drive AGN feedback.

description: We propose joint NuSTAR-XMM-Newton observations of a periodically variable quasar recently found from the Dark Energy Survey openParDESclosePar. The target is unique because its periodicity is highly significant and robust thanks to the sensitive DES imaging and a virgul20-yr long time baseline by combining DES with SDSS. The high sensitivity and long baseline are both crucial to rejecting false positives caused by quasars stochastic red noise variability. The proposed X-ray observations will test and distinguish two generic but different sets of models of circumbinary accretion disk simulations openPara central cavity vs. minidisksclosePar comma  which predict dramatically different X-ray fluxes. The results will provide an independent and complementary test for the binary black hole hypothesis to explain the periodicity.

It exhibits two widely-separated openPar940 kpcclosePar centers in the galaxy distribution with counterparts identified in a weak lensing analysis. From an SPT-SZ map comma  the cluster gas appears to be located in between the two peaks of the galaxy distribution and mass map comma  suggesting a dissociative merger.

The requested high-resolution X-ray observations will allow us to confirm the dissociated merger nature and to constrain the cluster X-ray temperature and luminosity to 10%. We request complementary HST observations to substantially improve the mass reconstruction using strong and weak gravitational lensing.

description: PDS 70 recently became an object of immense interest following the discovery of two newly forming planets orbiting in a gap in the star.s protoplanetary disc. The system is close enough to be directly imaged comma  providing unprecedented observations of the disc.s evolution. We have recently observed PDS 70 in X-ray and UV with the textitkeyOpen SwiftkeyClose  satellite and found that PDS 70 is in a short lived stage between the end of accretion and the final dispersal of the disc comma  which is thought to be driven by stellar X-ray and UV radiation. We propose 60 ks of XMM-Newton observations to obtain a far more detailed picture of the star.s coronal emissions comma  which will enable accurate modelling of the disc dispersion and the consequences for planet formation.

By connecting the requested XMM scan with the shallow all sky eROSITA survey comma  we will determine whether the activity in the Galactic disc is important for feeding and sustaining the Galactic corona. This study will provide us with an excellent archetype for advancing our understanding of galaxy evolution theory in a Milky-Way-class galaxy.

description: We propose a 60 ks observation to probe the nature of the youngest HMXB discovered with its associated SNR openParMCSNR J0513-6724closePar. The existing XMM-Newton observation shows tentative pulsations from the HMXB which needs confirmation. The estimated age is <6 kyr. A very young system can switch on as an accreting pulsar only when the spin period has reached a critical value. This implies an upper limit of B<5 10e11 G. A young NS observed with a low B strength would strongly imply magnetic field burial by an episode of post-supernova hyper-critical accretion comma  which if confirmed will be the first ever to be observed in a HMXB. A dedicated observation of MCSNR J0513-6724 will provide the unique opportunity to probe the physics of accretion onto NS at early evolutionary stages.

description: In the highly polarised NLS1 Mrk1239 comma  the primary X-ray emission from the inner black hole region appears to be completely absorbed revealing the underlying host galaxy emission.

With the highest sensitivity NuSTAR spectra comma  we will peer through the absorbing column to accurately determine the continuum model comma  the level of absorption comma  and the distant torus parameters.  Constraining the torus parameters will allow us to utilize simultaneous XMM RGS data to determine the origin of the photoionised emission at low energies.

These observations together with a wealth of existing HST and multi-wavelength data will allow us to fully characterize its X-ray binary populations on the basis of their compact objects and donor stars. This will provide a complete picture of the demographics of the compact objects in a typical spiral galaxy and together with population synthesis models will allow us to constrain their formation and evolution paths.

The popular explanation that they are cannibalistic remains of groups that lost energy through dynamical friction is not consistent with their typically lack the expected large cool cores.

description: We propose to observe a cool core cluster of modest X-ray luminosity which has over 10elev10 Msun of cold molecular gas in its X-ray cool core. ALMA data indicate that the cold gas is exceptionally disturbed and situated 5 kpc from the nucleus. If comma  as Hitomi has shown in the Perseus cluster comma  the cold gas and ICM share the same velocity field comma  then we shall measure velocity broadening of the X-ray emission lines with the XMM RGS. Star formation of about 40 Msunpyr is inferred from optical and IR data and a central cooling time of less than 5x10elev6 yr. A cooling flow at that rate will be detectable.

description: In the young system of WASP-18 the coronal emission is almost two orders of magnitude lower than expected for a star of its spectral type openParF6closePar and age openPar 800 MyrclosePar. The puzzling behavior could be explained as due to tidal interaction with its very massive hot Jupiter openPar10 M J closePar that prevents the formation of a magnetic dynamo in the shallow convective zone of the star and of thus of the corona. Here we want to observe the system of KELT-24 which is very similar to WASP-18. It is formed by an F5 star orbited by a massive hot Jupiter every 5 days. A measurement of its X-ray flux and luminosity derived from a 25 ks XMM-EPIC exposure can tell us if KELT-24 behaves like a young F type star of Hyades or if its X-ray activity is quenched by the interaction with its 5 M_J hot Jupiter.
