The High Energy X-ray Probe (HEX-P): The Circum-nuclear Environment of Growing Supermassive Black HolesEmbargoed
Feb 26, 2024
Daniel Stern, 2024, "The High Energy X-ray Probe (HEX-P): The Circum-nuclear Environment of Growing Supermassive Black Holes", https://doi.org/10.48577/jpl.SVQS4M, Frontiers in Astronomy and Space Sciences, JPL Open Repository
Ever since the discovery of the first Active Galactic Nuclei (AGN), substantial observational and theoretical effort has been invested into understanding how massive black holes have evolved across cosmic time. Circum-nuclear obscuration is now established as a crucial component,...
THE NuSTAR EXTRAGALACTIC SURVEYS: X-RAY SPECTROSCOPIC ANALYSIS OF THE BRIGHT HARD-BAND SELECTED SAMPLE
Sep 16, 2020
Daniel Stern, 2020, "THE NuSTAR EXTRAGALACTIC SURVEYS: X-RAY SPECTROSCOPIC ANALYSIS OF THE BRIGHT HARD-BAND SELECTED SAMPLE", https://doi.org/10.48577/jpl.E56NMC, Astrophysical Journal, JPL Open Repository
We discuss the spectral analysis of a sample of 63 Active Galactic Nuclei (AGN) detected above a limiting ux of S(8 􀀀 24keV) = 7 10􀀀14 erg s􀀀1 cm􀀀2 in the multi-tiered NuSTAR Extragalactic Survey program. The sources span a redshift range z = 0􀀀2:1, and have a median redshif...
The Unusual Broadband X-ray Spectral Variability of NGC 1313 X-1 seen with XMM-Newton, Chandra and NuSTAR
Sep 14, 2020
Daniel Stern, 2020, "The Unusual Broadband X-ray Spectral Variability of NGC 1313 X-1 seen with XMM-Newton, Chandra and NuSTAR", https://doi.org/10.48577/jpl.62MQVH, Monthly Notices of the Royal Astronomical Society, JPL Open Repository
We present results from the major coordinated X-ray observing program on the ULX NGC1313 X-1 performed in 2017, combining XMM-Newton, Chandra and NuSTAR, fo- cusing on the evolution of the broadband (∼0.3–30.0 keV) continuum emission. Clear and unusual spectral variability is obs...
