description: During its ongoing all sky survey comma  eROSITA is rapidly uncovering an increasing number of transients associated with galaxy nuclei which show no obvious signatures of prior AGN activity. A large fraction of these events is expected to be associated with TDEs. However comma  already the first results from dedicated follow-up campaigns of eROSITA-discovered events demonstrate that the reality is much more diverse and the deviations from the standard scenario of TDEs are common. Here comma  we ask for XMM-Newton ToO observations for 10 new nuclear non-AGN transients that will be discovered by eROSITA during AO20. The XMM data will provide vital information on the spectral and temporal evolution of this novel population of non-AGN nuclear transients and help deciphering their nature.

description: Super-Eddington accretion periods are expected to be extremely important to explain the fast growth of the first supermassive black holes. However comma among all accretion modes comma  this phase is still the least understood one comma and it is still largely debated what are the physical properties of the accretion flow and of the X-ray source at very high accretion rates. We propose here a systematic broad-band X-ray study of super-Eddington AGN at z<0.1 by simultaneously observing three sources with NuSTAR and XMM.These three AGN have the highest Eddington ratios in the SEAMBHs sample comma  which contains exclusively objects with black hole masses estimated from reverberation mapping comma  making the Eddington ratio estimates extremely reliable.

description: We propose a 42 ks observation of the galaxy group Nest 200047. LOFAR images with unprecedented sensitivity at low radio frequencies revealed a surprisingly complex filamentary structure related to the AGN feedback in this system comma  extending more than 200 kpc in radius. We interpret this unique morphology as being due to an old AGN bubble that is in the process of breaking up as it is buoyantly rising out of the group and interacting with the surrounding medium. To our knowledge comma  this is the most advanced stage of bubble evolution observed to date. The proposed exposure will allow us to quantify the morphology of the X-ray cavities associated with the large-scale radio lobes and perform a detailed analysis of the substructure and thermodynamical properties of this spectacular system.

description: The detection of gamma-ray emission from narrow-line Seyfert 1 openParNLS1closePar AGN confirms the presence of powerful relativistic jets in these sources. NLS1s have much lower black hole openParBHclosePar masses and higher accretion rates than the majority of blazars comma  therefore allowing investigations into how jets scale with the mass and accretion rate of the BH. Studies in the XMM band have shown that the tail of the accretion flow emission is present in the soft X-rays comma  whilst the jet dominates at higher energies. Thus comma  with X-ray and UV observations we can parameterise the accretion flow and simultaneously probe the non-thermal emission from the jet. We propose the first XMM observations of six newly-discovered gamma-ray NLS1s to explore the disc-jet connection and address issues of jet scaling and power.

description: We propose a deep XMM observation of the 1e14 Msun cluster XLSSC 105 at z=0.43 comma  which exhibits clear merging signatures in existing multi-wavelength data. The two peaks revealed by high-resolution SZ data do not have obvious counterparts in the existing shallow XMM data comma  which implies that this system is a high-velocity head-on merger along the plane of the sky. The two SZ peaks likely coincide with high-temperature openPar>virgul20 keVclosePar shock-heated regions. We propose a deep openPar175 ksclosePar XMM observation of this system to measure the temperature of the gas in the shocked regions and constrain the geometry of the merger comma  together with a joint 70ks Chandra high-resolution observation to detect the density jumps.

description: We propose a 147 ks XMM-Newton observation of the galaxy cluster RXC J0303.8-7752. Shallow observations show there is a tail-like structure with a length of 2-Mpc alongside the main cluster comma  which is the longest such feature ever reported. The deeper observations proposed here are needed in order to reveal the merging and the formation history of this rare tail comma  and in a broader text comma  to understand the heating and virialization processes of the ICM when accreting matter from subhalos.

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.

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 comma  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 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. This project will produce a legacy dataset that will be used in the future for multiple purposes comma  including multi-wavelength and time-domain investigations.

The observed tight correlation between Lx and T for a small sample of E galaxies suggests that the retention of hot gas openParpotential depthclosePar and the balance between heating and cooling is closely regulated.

However comma  theoretical predictions and numerical simulations suggest that the gas is in an outflow-wind state at these Lx comma  predicting an end to the correlation. We propose to constrain observationally the Lx-T relation at the lowest Lx to test the most substantial effect of the baryonic physics and provide the necessary confirmation of feedback recipes or the need for their corrections.

We propose to observe for 120 ks the bright AGN Mrk110 comma  simultaneously with HST-COS. The goal is to model for the first time the panchromatic broad line region emission in a Narrow Line Seyfertvirgul1 galaxy. We will use the broad lines from the optical comma  UV and X-rays in a global modeling that will characterize the stratification comma  extend and ionization of the broad line emitting region comma  whose X- ray extension still awaits a full characterization.

description: The X-ray emissions from exoplanet host stars are a key to understanding the evolution of planetary atmospheres. We propose X-ray and UV observations of 7 stars known to host multiple transiting super-Earths. The data will be combined with transit spectroscopy and synthesised EUV spectra to provide the crucial input for detailed atmospheric modelling. The proposed observations will almost double the sample of super-Earths with well characterised XUV radiation environments. The highest priority target is K2-18 which is the first exoplanet where the signature of water has been detected in its atmosphere. This study is designed to answer key questions about exoplanet atmospheres comma  including their evolution comma  evaporation comma  photochemistry and production of biologically significant molecules.

description: For more than 30 years comma  it has been assumed that a pc-scale torus produces a constant Compton-reflection component in heavily obscured AGN. We recently finished the 157-month Swift BAT processing and found to our surprise that nearly all of the brightest CT AGN are variable. We propose a variability study of 10 CT AGN with significant variability detected in multi-epoch NuSTAR observations at 2-10 keV comma  where a significant reflection component was detected comma  but none or only one high S-N soft X-ray observation exists so the observations are poorly constrained. This is a time critical opportunity to take advantage of a recent large set of legacy NuSTAR observations from this summer to study shorter virgul1 year-long variability periods in CT AGN.

Furthermore comma  the GRB softX-ray spectrum comma  usually unobserved by GRB instruments comma  can be reconstructed from the analysis of the dust scattered emission.

description: We have discovered a new type of brief but very energetic flaring phenomenon in two X-ray sources associated with old comma  compact star clusters around nearby galaxies. These sources flare by factors of >100 to X-ray luminosities 1-2 orders of magnitude larger than the Eddington limit of a neutron star on time scales of <1 minute comma  yet the process does not destroy the object. These flares represent the most energetic sources ever discovered in globular clusters. We propose XMM-Newton observations of one of these sources that flares repeatedly to catch the flare with the pn to provide better timing and spectra during a flare to constrain the mass and emission mechanism of these intriguing objects.

description: Previous X-ray observations of the AGN in IRAS 09149-6206 show evidence for some of the strongest reflection from the accretion disk observed among local comma  Compton-thin AGN. The unusually high reflection fraction indicates an extreme accretion geometry in which the intrinsic continuum emission experiences strong gravitational light bending comma  resulting in a broadband X-ray spectrum dominated by reflection from the inner accretion disk. We request a coordinated broadband X-ray observation of this remarkable source with XMM openPar70ksclosePar and NuSTAR openPar100ksclosePar. The quality of the data will enable us to robustly confirm the strong reflection comma  and utilize the full potential of the latest models to measure the black hole spin.
