XXL-HSC: Host properties of X-ray detected AGNs in XXL clusters
E. Drigga, E. Koulouridis, E. Pouliasis +10
There is compelling evidence that AGNs are strongly influenced by their environment. Therefore, studying the AGN population of clusters is essential, as both large-scale structures…
Steep-spectrum AGN in eROSITA Final Equatorial-Depth Survey (eFEDS): Their host galaxies and multi-wavelength properties
K. Iwasawa, T. Liu, Th. Boller +12
We selected sources with a steep soft-X-ray-band spectrum with a photon index larger than 2.5 -- measured by eROSITA on board the Spectrum-Roentgen-Gamma (SRG) -- from the eFEDS AG…
AGN X-ray luminosity function and absorption function in the Early Universe ()
E. Pouliasis, A. Ruiz, I. Georgantopoulos +15
The XLF of AGN offers a robust tool to study the evolution and the growth of SMBHs over cosmic time. Owing to the limited area probed by X-ray surveys, optical surveys are routinel…
ALMA Observations of Lyman-alpha Blob 1: Multiple major-mergers and widely distributed interstellar media
Hideki Umehata, Ian Smail, Charles C. Steidel +11
We present observations of a giant Lyman-alpha blob in the SSA22 proto-cluster at z=3.1, SSA22-LAB1, taken with the Atacama Large Millimeter/submillimeter Array (ALMA). Dust contin…
