The high energy X-ray probe (HEX-P): bringing the cosmic X-ray background into focus

Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 11 (2024)

Since the discovery of the cosmic X-ray background (CXB), astronomers have strived to understand the accreting supermassive black holes (SMBHs) contributing to its peak in the 10–40 keV band. Existing soft X-ray telescopes could study this populati

Publikováno v: Monthly Notices of the Royal Astronomical Society. 515:5185-5197

We present a new statistical method for constructing background subtracted measurements from event list data gathered by X-ray and gamma ray observatories. This method was initially developed specifically to construct images that account for the high

NuSTAR and XMM-Newton observations of luminous, heavily obscured, WISE-selected quasars at z \~ 2

The Astrophysical Journal

We report on a NuSTAR and XMM-Newton program that has observed a sample of three extremely luminous, heavily obscured WISE-selected AGN at z~2 in a broad X-ray band (0.1 - 79 keV). The parent sample, selected to be faint or undetected in the WISE 3.4
