The dynamical state of A548 from XMM-Newton data: X-ray and radio connection
L. Solovyeva, S. Anokhin, L. Feretti +5
We present a detailed study of the X-ray properties of the galaxy cluster Abell 548b (z=0.04), using XMM-Newton data, and discuss the connection between the thermal properties and…
The radio and X-ray properties of Abell 2255
L. Feretti, H. Boehringer, G. Giovannini +1
New radio and X-ray data are reported for the rich cluster Abell 2255. The cluster radio emission is characterized by the presence of a diffuse halo source, located at the cluster…
Status of the EPIC/MOS calibration
P. Ferrando, A. F. Abbey, B. Altieri +16
The XMM-Newton observatory has the largest collecting area flown so far for an X-ray imaging system, resulting in a very high sensitivity over a broad spectral range. In order to e…
Assembly bias and the redshift evolution of intrinsic alignments for LRGs
A. Herle, N. E. Chisari, H. Hoekstra +1
The intrinsic alignment (IA) of galaxies is one of the main contaminants to the weak lensing shear signal. Efforts to model it often assume that the alignment strength depends only…
Euclid: Precise inference of defocus wavefront error from image diffraction spike measurements
D. Neumann, L. Miller, H. Hoekstra +146
The success of the Euclid cosmological weak lensing measurements requires unprecedented knowledge of the point spread function (PSF) shape. Defocus wavefront errors induce variatio…
Automated scoring of the Ambiguous Intentions Hostility Questionnaire using fine-tuned large language models
Y. Lyu, D. Combs, D. Neumann +1
Hostile attribution bias is the tendency to interpret social interactions as intentionally hostile. The Ambiguous Intentions Hostility Questionnaire (AIHQ) is commonly used to meas…
The distant galaxy cluster CL0016+16: X-ray analysis up to
L. Solovyeva, S. Anokhin, J. L. Sauvageot +2
To study the mass distribution of galaxy clusters up to their Virial radius, CL0016+16 seems to be a good candidate,since it is a bright massive cluster, previously considered as b…
The X-ray Luminosity Function of Bright Clusters in the Local Universe
S. De Grandi, L. Guzzo, H. Böhringer +8
We present the X-ray luminosity function (XLF) for clusters of galaxies derived from the RASS1 Bright Sample. The sample, selected from the ROSAT All-Sky Survey in a region of 2.5…
The XMM-Newton Project
J. G. Bartlett, N. Aghanim, M. Arnaud +16
The abundance of high-redshift galaxy clusters depends sensitively on the matter density $\OmM$ and, to a lesser extent, on the cosmological constant . Measurements of this abu…
Optically-selected clusters at 0.8 < z < 1.3 in the EIS Cluster Survey
C. Benoist, L. da Costa, H. E. Jørgensen +9
This paper presents preliminary results of a spectroscopic survey being conducted at the VLT of fields with optically-selected cluster candidates identified in the EIS I-band surve…
A Flux-limited Sample of Bright Clusters of Galaxies from the Southern Part of the ROSAT All-Sky Survey: the Catalog and the LogN-LogS
S. De Grandi, H. Böhringer, L. Guzzo +8
We describe the selection of an X-ray flux-limited sample of bright clusters of galaxies in the southern hemisphere, based on the first analysis of the ROSAT All-Sky Survey data (R…
