Broad-line Region Clouds orbiting an AGN sample
J. Armijos-Abendaño, E. López, M. Llerena +1
We present a spectral and temporal analysis of XMM-Newton data from a sample of six galaxies (NGC 3783, Mrk 279, Mrk 766, NGC 3227, NGC 7314, and NGC 3516). Using the hardness-rati…
The XXL Survey: XLVIII; X-ray follow-up of distant XXL clusters: Masses, scaling relations and AGN contamination
R. T. Duffy, C. H. A. Logan, B. J. Maughan +10
We use deep follow-up XMM-Newton observations of 6 clusters discovered in the XXL Survey at to gain robust measurements of their X-ray properties and to investigate the exten…
Chandra follow up of the Hectospec Cluster Survey: Comparison of Caustic and Hydrostatic Masses and Constraints on the Hydrostatic Bias
Crispin H. A. Logan, Ben J. Maughan, Antonaldo Diaferio +4
Clusters of galaxies are powerful probes with which to study cosmology and astrophysics. However, for many applications an accurate measurement of a cluster's mass is essential. A…
Unsupervised star, galaxy, qso classification: Application of HDBSCAN
Crispin Logan, Sotiria Fotopoulou
Classification will be an important first step for upcoming surveys that will detect billions of new sources such as LSST and Euclid, as well as DESI, 4MOST and MOONS. The applicat…
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…
Study of diffuse HII regions potentially forming part of the gas streams around Sgr A*
J. Armijos-Abendaño, E. López, J. Martín-Pintado +8
We present a study of diffuse extended ionised gas toward three clouds located in the Galactic Centre (GC). One line of sight (LOS) is toward the 20 km s cloud (LOS0.11)…
