Inferring the morphology of AGN torus using X-ray spectra: A reliability study
Tathagata Saha, Alex G. Markowitz, Johannes Buchner
Numerous X-ray spectral models have been developed to model emission reprocessed by the torus of an active galactic nucleus (AGN), e.g., UXCLUMPY, CTORUS, and MYTORUS. They span a…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Galaxy Clusters and Groups in Disguise
Esra Bulbul, Ang Liu, Thomas Pasini +21
The eROSITA Final Equatorial-Depth Survey (eFEDS), executed during the performance verification phase of the Spectrum-Roentgen-Gamma (SRG)/eROSITA telescope, was completed in Nov.…
State-space representation of Matérn and Damped Simple Harmonic Oscillator Gaussian processes
Andrés Jordán, Susana Eyheramendy, Johannes Buchner
Gaussian processes (GPs) are used widely in the analysis of astronomical time series. GPs with rational spectral densities have state-space representations which allow O(n) evaluat…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Catalog of galaxy clusters and groups
A. Liu, E. Bulbul, V. Ghirardini +31
The eROSITA Final Equatorial-Depth Survey has been carried out during the PV phase of the SRG/eROSITA telescope and completed in November 2019. This survey is designed to provide t…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The first archetypal Quasar in the feedback phase discovered by eROSITA
M. Brusa, T. Urrutia, Y. Toba +18
Theoretical models of galaxy-AGN co-evolution ascribe an important role for the feedback process to a short, luminous, obscured, and dust-enshrouded phase during which the accretio…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The variability catalogue and multi-epoch comparison
Th. Boller, J. H. M. M. Schmitt, J. Buchner +10
The 140 square degree Final Equatorial-Depth Survey (eFEDS) field, observed with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) aboard the Spectrum-Roentgen…
