Dwarf AGNs from Optical Variability for the Origins of Seeds (DAVOS): Insights from the Dark Energy Survey Deep Fields
Colin J. Burke, Xin Liu, Yue Shen +69
We present a sample of 706, active galactic nuclei (AGNs) selected from optical photometric variability in three of the Dark Energy Survey (DES) deep fields (E2, C3, and…
The Growth of Intracluster Light in XCS-HSC Galaxy Clusters from
Kate E. Furnell, Chris A. Collins, Lee S. Kelvin +14
We estimate the Intracluster Light (ICL) component within a sample of 18 clusters detected in XMM Cluster Survey (XCS) data using deep ( 26.8 mag) Hyper Suprime Cam Subaru St…
The XXL survey XXXV. The role of cluster mass in AGN activity
E. Koulouridis, M. Ricci, P. Giles +15
We present the results of a study of the AGN density in a homogeneous and well-studied sample of 167 bona fide X-ray galaxy clusters () from the XXL Survey. The results…
The XXL Survey: XXXIII. Chandra Constraints on the AGN Contamination of z > 1 XXL Galaxy Clusters
C. H. A. Logan, B. J. Maughan, M. N. Bremer +11
Context. The XMM-XXL survey uses observations from XMM-Newton to detect clusters of galaxies over a wide range in mass and redshift. The moderate PSF of XMM-Newton means that point…
The XXL Survey: XXX. Characterisation of the XLSSsC N01 supercluster and analysis of the galaxy stellar populations
V. Guglielmo, B. M. Poggianti, B. Vulcani +34
Superclusters form from the largest enhancements in the primordial density perturbation field and extend for tens of Mpc, tracing the large-scale structure of the Universe. We char…
Correlations between X-ray properties and Black Hole Mass in AGN: towards a new method to estimate black hole mass from short exposure X-ray observations
Julian A. Mayers, Kathy Romer, Arya Fahari +14
Several investigations of the X-ray variability of active galactic nuclei (AGN) using the normalised excess variance () parameter have shown that variability has a…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
The XXL survey XV: Evidence for dry merger driven BCG growth in XXL-100-GC X-ray clusters
S. Lavoie, J. P. Willis, J. Democles +33
The growth of brightest cluster galaxies is closely related to the properties of their host cluster. We present evidence for dry mergers as the dominant source of BCG mass growth a…
The XXL Survey X: K-band luminosity - weak-lensing mass relation for groups and clusters of galaxies
F. Ziparo, G. P. Smith, S. L. Mulroy +15
We present the K-band luminosity-halo mass relation, , for a subsample of 20 of the 100 brightest clusters in the XXL Survey observed with WIRCam at the Canad…
