Extreme ultra-soft X-ray variability in an eROSITA observation of the Narrow-Line Seyfert 1 Galaxy 1H 0707-495
Th. Boller, T. Liu, P. Weber +9
The ultra-soft narrow-line Seyfert 1 galaxy 1H 0707-495 is a well-known and highly variable active galactic nucleus (AGN), with a complex, steep X-ray spectrum, and has been studie…
Probing the anomalous positron fraction origin with fully leptonic decaying gravitino dark matter candidates
Johannes Buchner, Edson Carquin, Marco A. Díaz +3
The flux of electron and positron cosmic rays measured by the space-based experiments PAMELA, AMS-02, CALET, DAMPE and Fermi-LAT shows an unexpected behaviour at high energies, in…
The Sloan Digital Sky Survey Reverberation Mapping Project: the XMM-Newton X-ray source catalog and multi-band counterparts
Teng Liu, Andrea Merloni, Torben Simm +10
The XMM-RM project was designed to provide X-ray coverage of the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) field. 41 XMM-Newton exposures, placed surrounding the Cha…
Relativistic accretion disk reflection in AGN X-ray spectra at z=0.5--4: a study of four \textit{Chandra} deep fields
Linda Baronchelli, Kirpal Nandra, Johannes Buchner
We confirm that the spectra are best fit by a model containing two Compton reflection components, one from distant material, and the other displaying relativistic broadening, most…
The MAVERIC Survey: Chandra/ACIS Catalog of Faint X-ray sources in 38 Galactic globular clusters
Arash Bahramian, Jay Strader, James C. A. Miller-Jones +11
Globular clusters host a variety of lower-luminosity ( erg s) X-ray sources, including accreting neutron stars and black holes, millisecond pulsars, cataclysmic…
Dalek -- a deep-learning emulator for TARDIS
Wolfgang E. Kerzendorf, Christian Vogl, Johannes Buchner +3
Supernova spectral time series contain a wealth of information about the progenitor and explosion process of these energetic events. The modeling of these data requires the explora…
