5. NHXM: Core scientific objectives Black hole cosmic evolution and accretion physics Acceleration mechanisms and non-thermal emission - resolve at least 60-70% of the CXB in the energy range where it peaks (20 -30 keV) - constrain the physics of the accretion flow onto both SMBH and solar mass BH - solve the puzzle on the origin of the hard X–ray emission from the Galactic centre -constrain acceleration processes in relativistic Jets of blazars and GRB -measure the maximum energy of electron acceleration in supernova remnants shocks -Shock development and cosmic ray production in SNR and intra-cluster medium Physics of matter under extreme conditions -Behaviour of matter in extreme gravitational and magnetic fields -Emission line profiles, continuum shape and polarization properties used to estimate BH spin -Polarization measurements & Broad cyclotron resonance in high magnetic field X-ray pulsars to study the transfer of radiation and determine field geometry

9. Acceleration mechanisms Jet emission is due to both synchrotron and IC, both BB components and strongly polarized. Therefore, multi-band (IR,O,X-ray) spectroscopy and polarimetry can probe – jet structure – nature of jet seed photons – jet power

10. X-ray Polarimetry with imaging capabilities The possibility to associate to the polarimetric sensitivity also an imaging capability is of paramount importance in the case of extended sources investigation, like e.g. the SN remnants and the GC region. 10

11. Missing SMBH Geometry of the torus: the polarization angle will give us the orientation of the torus, to be compared with IR results, and with the ionization cones

12. Polarimetric sensitivity Soft X-ray channel Hard X-ray channel Two polarimetric channels (2 – 10 keV and 10 – 35 keV) for an effective diagnostic of the emission mechanisms Cross correlation with the spectroscopy data between 2 and 36 keV! 12

26. Summary The discovery space of the NHXM mission is extremely wide; also thanks to the addition of simultaneous imaging polarimetry and wide field X-ray monitor. This is achievable by the small/medium-size NHXM project, exploiting already available technology in mirror and detector manufacturing, well within the next decade. NHXM is a big step forward following on the hard X-ray focusing missions NUSTAR and ASTRO-H and on the polarimetric GEMS mission. NHXM will also be a good precursor for IXO, testing various technologies that are foreseen on a much larger scale for IXO. All technologies have old and strong roots, building up on the BeppoSAX, XMM, INTEGRAL, AGILE & Swift heritage and on the recent technological advance made for the mirrors, polarimeter, detectors and truss. The NHXM proposal submitted to ESA was based on 50% of the M3 budget with a launch in the time frame 2020. A strong international team has been formed. 26
