X-ray emission from a rapidly accreting narrow-line Seyfert 1 galaxy at z=6.56
Julien Wolf, Kirpal Nandra, Mara Salvato +14
This study aims at identifying luminous quasars at among X-ray-selected sources in the eROSITA Final Equatorial-Depth Survey (eFEDS) in order to place a lower limit on blac…
The first look at Narrow-Line Seyfert 1 Galaxies with eROSITA
G. Grünwald, Th. Boller, S. Rakshit +6
We present the first look at the spectral and timing analysis of Narrow-Line Seyfert 1 Galaxies (NLS1s) with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA)…
The demographics of obscured AGN from X-ray spectroscopy guided by multiwavelength information
Brivael Laloux, Antonis Georgakakis, Carolina Andonie +10
A complete census of Active Galactic Nuclei (AGN) is a prerequisite for understanding the growth of supermassive black holes across cosmic time. A significant challenge toward this…
Abundance and temperature of the outer hot circum-Galactic medium: The SRG/eROSITA view of the soft X-ray background in the eFEDS field
G. Ponti, X. Zheng, N. Locatelli +14
Despite their vital importance to understand galaxy evolution and our own Galactic ecosystem, our knowledge of the physical properties of the hot phase of the Milky Way is still in…
Optimized Photometric Redshifts for the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS)
Dritan Kodra, Brett H. Andrews, Jeffrey A. Newman +27
We present the first comprehensive release of photometric redshifts (photo-z's) from the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) team. We use stati…
Investigating the Effect of Galaxy Interactions on Star Formation at 0.5<z<3.0
Ekta A. Shah, Jeyhan S. Kartaltepe, Christina T. Magagnoli +24
Observations and simulations of interacting galaxies and mergers in the local universe have shown that interactions can significantly enhance the star formation rates (SFR) and fue…
