description: We propose to complete the last 10% of high-quality observations for the eeHIFLUGCS galaxy cluster sample openPar31 of 376 clustersclosePar. The sample is based on ROSAT with completely and homogeneously redetermined fluxes as well as updated redshifts. For the already observed clusters we have also identified >10 double-triple clusters and clusters dominated by AGN emission comma  which then fall below the flux limit of 5e- 12 erg-s-cm2. With the completed follow-up observations we will decrease the uncertainties in OmegaM by a factor of 2.8 compared to those obtained with the HIFLUGCS sample. If these 10% do not get observed comma  the flux-limited sample drops by almost a factor of 3 to a disappointing 137 clusters. The observations will have long lasting legacy value for a range of astrophysical studies

description: IGR 12580+0134 is one of rare TDEs found with off-beam relativistic jet comma  and is by far the nearest TDE ever found openPardvirgul17MpcclosePar. The source presented extremely unusual evolution of X-ray lightcurve comma  with a rapid flux drop at virgul600 days followed by a weak but nearly constant X-ray emission that was visible at least until virgul2600 days after the stellar capture. This cannot be explained by standard tidal disruption theories comma  but may be a Compton echo effect resulting from the Thomson scattering between primary X-rays and its surrounding gas. The goal of XMM proposal is to obtain high quality X-ray spectrum to test the Compton echo scenario for interpreting the residual X-ray emission. If confirmed comma  the observation will enable to constrain the size comma  density and geometry of the surrounding gas to BH.

description: We propose to follow-up an interesting X-ray source discovered in the field of an unidentified 3FGL Fermi source. Ther 3FGL source has GeV properties consistent with those of young pulsars and PWNe.

This exoplanet is located just 0.017 au from its G7V host star comma  in the middle of the so-called Neptunian desert comma  and its survival under presumably intense X-ray irradiation is a mystery.

These observations are essential to determine the emission mechanism responsible for the CAGN and hence push towards a complete census of black hole growth  evolution.
