XXL-HSC: An updated catalogue of high-redshift () X-ray AGN in the XMM-XXL northern field. Constraints on the bright end of the soft logN-logS

E. Pouliasis, I. Georgantopoulos, A. Ruiz +12

X-rays offer a reliable method to identify Active Galactic Nuclei (AGN). However, in the high-redshift Universe X-ray AGN are poorly sampled due to their relatively low space densi…

The XXL survey: XLVI. Forward cosmological analysis of the C1 cluster sample

Christian Garrel, Marguerite Pierre, Patrick Valageas +15

We present the forward cosmological analysis of an selected sample of galaxy clusters out to a redshift of unity. Following our previous 2018 study based on the dn/dz quantit…

Understanding X-ray and optical selection of galaxy clusters: A comparison of the XXL and CAMIRA cluster catalogues obtained in the common XXL-HSC SSP area

J. P. Willis, M. Oguri, M. E. Ramos-Ceja +31

Large samples of galaxy clusters provide knowledge of both astrophysics in the most massive virialised environments and the properties of the cosmological model that defines our Un…

The XXL survey: XLII. Detection and characterization of the galaxy population of distant galaxy clusters in the XXL-N/VIDEO field: A tale of variety

A. Trudeau, C. Garrel, J. Willis +16

Context. Distant galaxy clusters provide an effective laboratory in which to study galaxy evolution in dense environments and at early cosmic times. Aims. We aim to identify distan…

The XXL Survey. XLI. Radio AGN luminosity functions based on the GMRT continuum observations

B. Slaus, V. Smolcic, M. Novak +15

We study the space density evolution of active galactic nuclei (AGN) using the radio survey of the XXL-North field, performed with the Giant Metrewave Radio Te…

The survey: XL. Obscuration properties of red AGN in

V. A. Masoura, I. Georgantopoulos, G. Mountrichas +6

The combination of optical and mid-infrared (MIR) photometry has been extensively used to select red active galactic nuclei (AGNs). Our aim is to explore the obscuration properties…
