description: Red nuggets the relics of the first massive galaxies can be observed in the high-redshift (zvirgul2) universe. Their local analogs form a more scarce population with only a few confirmed examples. However due to their proximity only this nearby population allows for detailed studies. X-ray observations are especially important as they may provide a unique snapshot on the first phase of the formation of galaxies and their central black hole (BH) and on the more recent evolution of these systems. To double the sample of local relics with X-ray information we propose joint Chandra and XMM-Newton observation of two relic galaxies. Our proposed program will establish a complete X-ray survey of nearby isolated relic galaxies and probe the relation between BHs bulges and dark matter halos. [truncated!

description: Covering the central 20*2.5deg2 of the Milky Way disc with 20ks XMM exposures will allow us to measure the flows of hot baryons emerging from the energetic activity in the disc to detail their impact on the surroundings and to connect the sources in the disc with the base of the Galactic outflow. By connecting the requested XMM scan with the shallow all sky eROSITA survey 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: The Event Horizon Telescope (EHT) is effectively an Earth-sized interferometric mm-band telescope array with 20 microarcsec spatial that is conducting ground-breaking observations of distant supermassive black hole (SMBH) systems resolution. These emission size scales are consistent with those inferred from X-ray and gamma-ray variability thus our request for joint XMM-Newton/NuSTAR /Chandra/EHT observations of a particularly interesting SMBH MKN 501. MKN 501 belongs to a subclass of systems that may consist of a close pair of binary black holes. Along with contemporaneous EHT observations approved for Spring 2019 joint XMM-Newton/NuSTAR study of MKN 501 will provide combined broad-band X-ray spectra and variability while Chandra can provide arcsecond imaging.

description: Modelling of the waveform of the X-ray pulsations of accreting ms pulsars (AMSP) is one of the most promising ways to constrain the equation of state of neutron stars. However it requires an extremely high number of counts to break the degeneracy between the many parameters that shape the X-ray pulse profiles. The polarimetric information granted by the forthcoming IXPE mission will measure the geometry of the hot spots independently easing the requirement. We propose a 120 ks XMM-NuSTAR ToO observation of the next outburst of an AMSP to measure the pulsar ephemeris and fold simultaneous IXPE data model the broadband spectrum and derive a high statistics energy-resolved pulse profile. The proposed observation will measure the mass and the radius with an accuracy of a few per cent. [truncated! Please see actual data for full text]

description: We propose to complete a unique XMM study of 7 galaxy groups selected by UV absorption in HST/COS spectra of background quasars. Combining X-ray and UV observations of these groups will yield new constraints on the state and locations of the systems. baryons. The  groups are similar in velocity dispersion (virgul300-500 km/s) and richness. All have broad Ly-alpha absorption and but only 4 have detectable OVI absorption.  XMM observations show that 2 with OVI are associated with clear X-ray dominant groups while the other observed 3 lacking OVI are not. We are proposing to observe the remaining two OVI-absorbing systems. We will test predictions from current numerical simulations for thermodynamic properties of multiphase gas feedback mechanisms merger history and star formation history. [truncated!

title: 088269

description: We propose XMM-Newton observation of the recently discovered old pulsar J0533-4524. The low absorption will allow us to accurately measure the soft X-ray spectrum and detect emission from the hot polar cap. If the polar cap emission turns out to be bright this pulsar will be an important target for future X-ray studies probing the properties of NS interior atmosphere and magnetosphere. Although old pulsars are poorly studied outside the radio band because of their faintness at an age of 1-100 Myrs they are expected to emit thermal radiation dominating in soft X-rays and far-UV and magnetospheric radiation dominating at other wavelengths. The proposed observations will allow us to study both components and probe the properties of the neutron star magnetosphere surface and interior. [truncated! Please see actual data for full text]

description: PG1448+273 is a luminous Narrow Line Seyfert 1 galaxy thought to be accreting at the Eddington limit. An XMM-Newton observation in 2017 captured an ultra fast outflow in PG1448+273 via a deep Fe absorption trough between 7-8 keV with an outflow velocity of 0.1c. The AGN has never been observed at hard X-rays. We propose a simultaneous NuSTAR (120 ks) and XMM-Newton (75 ks) observation to quantify the physical properties of the fast wind. The observations will  (i) provide a realistic estimate of the mass outflow rate and wind energetics (ii) probe variations in the wind in response to the continuum and (iii) measure the broadband SED and quantify the mass accretion rate and Eddington ratio. The observations will test the plausibility of radiation driven winds near the Eddington limit. [truncated! Please see actual data for full text]

description: With the first discovery of a NS merger detected with gravitational wave facilities and ongoing detections of SGRBs detected with gamma-ray satellites it is a golden era to make significant progress in merger studies. A critical link between these populations is the production of relativistic jets and the fraction of mergers that produce relativistic SGRB-like outflows. Deep X-ray observations have played an important role in constraining the collimation of SGRBs as our current knowledge of the opening angle distribution comes almost exclusively from X-ray observations at  and amp amp amp gt 1 day after the burst. Here we propose for XMM-Newton TOO observations to monitor a SGRB afterglow and constrain its opening angle which will have significant implications for the energy scales and event rates. [truncated!

description: Accretion inevitably produces disk winds which has vast consequences. These outflows can regulate the accretion process affect the long-term orbital evolution of the X-ray binary and impact their cosmic environment. However it is not established exactly how disk winds are launched and how much mass is carried away by them. We propose to study the disk wind of a persistently accreting neutron star across the electromagnetic spectrum with XMM-Newton HST and VLT. These simultaneous multi-wavelength data will determine the launch mechanism and mass content of the disk wind. This show-case study will highlight the impact of studying disk winds across the electromagnetic spectrum and pave the way for future observing programs. [truncated!

description: The impact of projection effects on optical photometric galaxy cluster selection has recently been clarified at z virgul 0.1 using extensive spectroscopy of putative member galaxies. The projected fraction of photometrically associated galaxies has been constrained as a function of richness along with the relations between photometric and spectroscopically-corrected richness and velocity dispersion. We propose XMM-Newton observations of a complete sub-sample of these clusters at high richness to obtain low-scatter X-ray mass proxies. These measurements will provide independent complementary information on projection effects and crucially will allow the scatter of spectroscopically-corrected richness with mass to be quantified.

We notice a trail of galaxies in the northeast direction seemingly being accreted onto the clump itself and co-spatial with an apparent X-ray surface brightness excess.

description: We propose an in-depth X-ray study of fast blue optical transients (FBOTs) a new class of transients with luminosities and time scales that challenge traditional SN models. Alternative scenarios include a failed SN of a stripped star He-shell detonation on a white dwarf and a SN shock breaking through a dense medium. FBOTs have mostly been studied in the optical/UV regime which is of thermal origin and it is not sensitive to the nature of the underlying energy source. Here we propose to capitalize on our recent discovery of X-rays from the FBOT AT2018cow with unprecedented properties and start the first broad-band X-ray monitoring campaign of FBOTs. The primary goal is to test for the presence of engines driving the explosions and constrain their nature. [truncated! Please see actual data for full text]
