description: We propose to continue our very successful program to use the observed cooling of the crusts in transiently accreting neutron star X-ray binaries to probe the behavior of ultra-dense matter. Those crusts are heated due to the accretion of matter during the outbursts of those transients. After the outbursts are over the crusts cool until they are in equilibrium with the cores again. Following this cooling process for several systems has given us important insights in the structure of neutron stars comma  but many uncertainties remain. Therefore it is needed to enlarge our sample to obtain better insights in the behavior of how neutron stars react to the accretion of matter. Our program combines the strengths of Chandra and XMM-Newton and has proven to be excellently suited to obtain those goals.

We shall cover all MOS2 CCDs and in addition we add 3 more raster points in the central one. Based on the previous observations comma  using an exposure time of 10 ks per observation comma  we shall achieve excellent statisticsdoublePoint expected 4000 counts in the hard band CORCHETE_OPEN2-10CORCHETE_CLOSE keV comma  sufficient to allow derivation of the vignetting with small uncertainties.  G21.5-00.9 has an excellent visibility for full revolutions in March-April 2021 comma  thus all 9 rasters could fit into one revolution.

description: We propose a deep XMM-Newton observation of the peculiar and nearby young radio galaxy PKS 1718-649 to investigate the possibility of an accretion-disk wind. This unique case provides high chances to observe and study in detail the first wind outflow in a jetted AGN at its early evolutionary stage. We base our proposal on two previous low-exposure XMM-Newton observations that we acquired in AO16-17. We find barely significant blueshifted features of highly ionized H-He- like iron around 7-8 keV. Due to the low flux of this system comma  only a deeper observation can constrain the nature and parameters of a potential outflow in PKS 1718-649.

description: ZTF has enabled the discovery of a new class of LINERs d_commaturning ond_comma into AGN with dramatic optical spectroscopic transformations. For the most rapid transition into a NLS1 comma  real-time monitoring revealed the presence of a prominent soft excess and a luminous X-ray flare delayed with respect to the optical rise by 2 months. The proposed program will test physical mechanisms driving this new class of changing-look LINERs with joint XMM-NuSTAR observations by measuring the response of the reprocessed hard X-ray continuum in these nine objects. We wish to map out the structure of the accretion flow state change comma  view for the first time this new class of changing-look LINERs in the hard X-rays comma  and contrast their spectral properties with that of broad line and changing-look Seyferts.

description: We propose a 60ks observation for one new GeV bright nova to explore the particle acceleration and gamma-ray production mechanisms. We will constrain the particle acceleration efficiency by comparing thermal X-ray to GeV luminosity and search for predicted non-thermal X-rays. Understanding shocks in novae is relevant for other shock-powered transients including Type IIn supernovae comma  tidal disruption events and stellar mergers. NuSTAR is the only instrument capable of detecting X-rays from novae simultaneously with the GeV emission openParthe lower energy X-rays accessible to other focusing instruments are hidden by the nova shell at these timesclosePar. The observations should be conducted now to take advantage of the simultaneous operations with Fermi-LAT.

description: We request MAGIC observations to provide sensitive VHE coverage for the multi-instrument campaigns in2021-2022. 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. This experimental work allows addressing fundamental questions on how Mrk421 and Mrk501 function comma  which may be generalized to other blazars that are more difficult to study because they are weaker or located further away. The multi-year MAGIC data we are collecting provide unprecedented VHE coverage with high sensitivity and low energy threshold and comma  together with the related MWL data openParincluding striclty simultaneous observationsclosePar comma will become one of the MAGIC legacy products.

During AO17 we were awarded a LP aimed at searching for new PULXs within 8 fields containing promising candidates. So far we obtained data for half of sample and we discovered one new PULX. This result confirms the goodness of the LP adopted strategy and that a relatively large fraction of ULXs likely hosts an accreting NS. The present proposal is aimed at observing two bright openParhigh fluxclosePar ULXs in Timing mode and at looking for coherent signals over a period range openPar1ms<P<100msclosePar. The detection of even one very fast PULX would be very important for constraining NS accretion models as well as binary systems.

description: Specific abundance patterns are left by distinct chemical enrichment processes during the formation and evolution of galaxies. We propose to observe the luminous infrared galaxy Arp 299 with a total exposure of 130 ks. The existing RGS spectrum with a short exposure yields rather high Mg-O and Ne-O abundance ratios openParwith large uncertaintiesclosePar in the hot atmosphere of the host galaxy. Core-collapse supernovae are the main metal factory of these elements. Nonetheless comma  the observed abundance ratios are in tension with various initial mass function weighted yields at the 1-2 sigma confidence level. Combining the archival and proposed observations comma  we can accurately measure the metal abundances. We will explore possible origins of the unusual abundance ratios.

This will help to clarify several long-standing questions related to the accretion physics in low-luminosity XRB comma  their numbers comma  origin comma  and evolution. To fully realise this potential comma  follow-up observations in X-ray and other bands are comma  however comma  essential. Here we propose to start the exploration of this new exciting dataset with XMM-Newton and follow-up several new High mass X-ray binary openParHMXBclosePar candidates identified with Rosita in order to confirm preliminary identification and study their X-ray properties in detail.

The line-of-sight column density openParNH_losclosePar of the obscuring material should vary over weeks to months comma  but such an evidence has been observed only in a few X-ray detected AGN comma  due to lack of large samples of heavily obscured AGN with multi-epoch observations. We propose for a XMM monitoring of NGC 1358 comma  a nearby Compton thick openParCT-closePar AGN with small torus covering factor and NH_los significantly larger than the torus average column density. Through this monitoring comma  we expect to measure significant variability in NH_los and detect a transition from CT- to Compton thin comma  thus improving our knowledge on the properties of the obscuring material surrounding AGN.

description: As the largest and most energetic single objects in the Universe comma  giant radio galaxies openParGRGsclosePar comma  are of particular interest as they are less common but extreme examples of radio source evolution. No unified model has emerged to explain the properties of this extreme class of radio galaxies. Previous studies of GRGs are mostly at radio and optical bands comma  and there is a lack of systematic study of GRGs in X-rays. As the energetic radio jets of GRGs extend outwards comma  they interact with the surrounding medium. We select a complete sample of nearby GRGs and propose new XMM observations to complete the X-ray coverage of the sample to study the X-ray properties of GRGs and their environments comma  which helps to understand the processes responsible for the formation and evolution of GRGs.

description: The combination of in-situ measurements from the Juno spacecraft and remote X-ray observations have provided tantalising clues towards the processes that permit rapidly-rotating magnetised bodies to produce X-ray aurora. Since Juno does not carry an X-ray instrument comma  AO 18 presents unique opportunities which may definitively identify the acceleration process-es that allow Jupiter to produce X-ray aurorae. We willdoublePoint1. Identify whether magnetic unloading triggers the X-ray aurora by testing for correlations between X-ray auroral emissions and simultaneous Juno measurements of the plasma sheet. 2. Identify and quantify the auroral acceleration process-es at Jupiter by testing for correlations between X-ray spectral fluxes and in-situ electron and ion fluxes and multi-waveband observations.

Past observations have revealed a peak-shift towards higher energies hinting an EHBL-like nature comma  fast intranight and longterm variability as well as complex correlation patterns between wavebands.

The current spectrum of the knot shows strong emission lines from Fe-peak elements openParCr comma  Mn comma  NiclosePar comma  pointing to an origin in the deepest layer of a near-Chandrasekhar-mass WD. However comma  due to high background in the Chandra data comma  it is difficult to claim a significant detection of the Ni line comma  which is key to determining the burning regime. Thanks to low background comma  high sensitivity in the Ni band comma  only the XMM-Newton can resolve this important issue in SN Ia physics.

Even in January 2019 openParlast high S-N XMM observationclosePar the line flux only dropped by a factor of 5. Thus comma  we still expect a significant evolution of the line. A joint short HST observation is also requested to maximize the scientific return of the XMM investment and to study the connection of the X-ray emitting corona and the UV accretion disk.

The compact object openPara white dwarf or a neutron starclosePar has a spin period of 13 s and has been steadily spinning up at 2x10elevkeyOpen -15keyClose  s-s for the last 20 years. Independently of its NS or WD nature comma  this spin-up is difficult to explain with the angular momentum that accretion can supply.

description: The hard X-rays from accreting white dwarfs openParWDsclosePar in magnetic cataclysmic variables openParCVsclosePar are produced by shock-heating in the accretion column comma  and the measured temperature depends on the mass of the WD. By obtaining high-quality hard X-ray spectra comma  it is possible to measure the temperature and constrain the WD mass. An important question is whether the WD mass distribution extends up to the Chandrasekhar limit. The best place to look for high-mass WDs is among CVs with the hardest spectra comma  making CVs found in the 20-100 keV INTEGRAL survey good candidates for having more massive WDs. We propose NuSTAR and XMM observations of two IGR CVs.

description: The X-ray spectrum of BF Eri contains a puzzling contradiction. BF Eri is the optical counterpart of an Einstein slew survey source 1ES0437-046 comma  and was identified as a cataclysmic variable with a massive openPar>1.23 MsunclosePar white dwarf. As such comma  we expect a hot comma  optically-thin comma  thermal plasma with prominent emission lines of He-like and-or H-like iron. No such lines are seen in the Suzaku observation comma  showing instead a continuum-dominated spectrum. While this could be due to a low abundance of iron comma  the equivalent width of the 6.4 keV line suggests a near-solar abundance. Here we propose an XMM-Newton observation of BF Eri to confirm and refine comma  or refute comma  these Suzaku results comma  with the aim of constructing a model for the X-ray emission from BF Eri with a single abundance of iron.

description: The X-ray spectrum of the colliding-wind binary WR140 at apastron is produced under benign conditions of minimum density and minimum orbital velocity and forms the initial plasma state from which subsequent evolution occurs. The star.s precise orbit comma  exceptional X-ray brightness comma  rich observational history and characteristic X-ray temperature very similar to that of the Perseus Cluster of Galaxies make it the ideal reference for calibration of models of plasmas produced under dynamical and thermodynamical conditions similar to those that hold in a variety of prominent X-ray sources. As well as precise tests of predicted photometry comma  a joint RGS-HETG high-resolution spectrum will test a predicted emission-line redshift at apastron.

description: Between 2007 and 2017 comma  our yearly XMM-Newton monitoring of SN1987A yielded EPIC and RGS spectra of unprecedented quality. The fluxes and broadening of the numerous emission lines provide information on the evolution of the X-ray emitting plasma and its dynamics. The soft X-ray light curve shows a mild flattening after 2006 and a flux decrease since 2014. To further monitor the evolution of the X-ray flux and to follow the expected turn-over we propose to continue our monitoring. This will allow us to further study the time evolution of the shock conditions and abundance profiles. At high energies EPIC-pn can help to clarify the extremely low observed Fe abundance by following the evolution of the detected Fe-K line.

Many of the planets are located in or near the presumed habitable zones of their host stars. The targets cover stellar types from F to M. While a star.s photometric luminosity is important comma  the high energy UV-X-ray irradiation from the corona is a major driver of photochemistry comma  upper atmospheric heating comma  and atmospheric mass loss in exoplanets. We will obtain a snapshot of the current temperatures and fluxes using EPIC-PN-MOS. These data will start the process of understanding the possible paths of atmospheric evolution.

description: During their soft state edge-on black hole transients show blue-shifted absorption lines in their X-ray spectra due to hot and equatorial disk winds. Blue-shifted absorption lines have also been discovered in optical and ultravioletopenParUVclosePar. These features must be produced in an outflow comma  but the physical conditions required to form them are very different. The three feautures have never been observed at the same time. It is unclear if they are linked to distinct outflows or simply with different regions. We propose to answer this question with simultaneous time-resolved spectroscopy of a high-inclination soft-state system in the X-ray comma  UV and optical bands. This will allow us to test if the three types of wind features are present simultaneously and whether they display correlated variability.

We aim to detect the hottest and densest phase of the Warm Hot Intergalactic Medium in the vicinity of clusters by its thermal soft X-ray emission. For this purpose comma  we will use the XMM-Newton observations to correct precisely for the point sources comma  resulting in an improvement of the temperature measurement uncertainty by a factor of three.

description: SDSS-C4 3028 is a cluster of galaxies identified in the Sloan Digital Sky Survey. It stands out as a nearby cluster containing a surprisingly large fraction of star forming galaxies comma  which is not fully understood in the standard model of galaxy evolution. It is also very unusual that the brightest galaxy of this cluster is a passive red spiral galaxy. We propose an XMM pointing that covers the entire cluster to determine its dynamical state and to obtain a more robust cluster mass measurement. We will also verify whether this passive red spiral galaxy is the brightest cluster galaxy residing at the the bottom of the gravitational potential of this cluster. SDSS-C4 3028 provides a valuable opportunity to study the evolutionary link between galaxies and clusters.
