The International Axion Observatory (IAXO): case, status and plans. Input to the European Strategy for Particle Physics
A. Arcusa, S. Ahyoune, K. Altenmuller +120
The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions with unprecedented sensitivity. IAXO holds a unique position in…
The evolution of the heaviest super-massive black-holes in jetted AGNs
Alessandro Diana, Alessandro Caccianiga, Alberto Moretti +3
We present the space density evolution, from z=1.5 up to z=5.5, of the most massive (MM) black holes hosted in jetted Active Galactic Nuclei(AGNs). The analysis…
X-ray obscuration from a variable ionized absorber in PG 1114+445
R. Serafinelli, V. Braito, P. Severgnini +9
Photoionized absorbers of outflowing gas are commonly found in the X-ray spectra of active galactic nuclei (AGN). While most of these absorbers are seldom significantly variable, s…
The Impact of the CMB on the Evolution of high-z Blazars
L. Ighina, A. Caccianiga, A. Moretti +3
Different works have recently found an increase of the average X-ray-to-radio luminosity ratio with redshift in the blazar population. We evaluate here whether the inverse Compton…
X-ray properties of z>4 blazars
L. Ighina, A. Caccianiga, A. Moretti +4
We present the X-ray analysis of the largest flux-limited complete sample of blazar candidates at z>4 selected from the Cosmic Lens All Sky Survey (CLASS). After obtaining a nearly…
Water masers in Compton-thick AGN II. The high detection rate and EVN observations of IRAS 15480-0344
P. Castangia, G. Surcis, A. Tarchi +3
Investigations of HO maser galaxies at X-ray energies reveal that most AGN associated with water masers are characterized by high levels of absorption. With the aim of finding…
