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…
Shapes and alignments of dark matter haloes and their brightest cluster galaxies in 39 strong lensing clusters
Taizo Okabe, Masamune Oguri, Sébastien Peirani +6
We study shapes and alignments of 45 dark matter (DM) haloes and their brightest cluster galaxies (BCGs) using a sample of 39 massive clusters from Hubble Frontier Field (HFF), Clu…
Cosmological evolution of orientations of cluster-sized dark matter haloes and their central galaxies in the Horizon-AGN simulation
Taizo Okabe, Takahiro Nishimichi, Masamune Oguri +6
It is known observationally that the major axes of galaxy clusters and their brightest cluster galaxies are roughly aligned with each other. To understand the origin of the alignme…
Halo Concentration, Galaxy Red Fraction, and Gas Properties of Optically-defined Merging Clusters
Nobuhiro Okabe, Masamune Oguri, Hiroki Akamatsu +9
We present multi-wavelength studies of optically-defined merging clusters, based on the Hyper Suprime-Cam Subaru Strategic Program. Luminous red galaxies, tracing cluster mass dist…
Projected alignment of non-sphericities of stellar, gas, and dark matter distributions in galaxy clusters: analysis of the Horizon-AGN simulation
Taizo Okabe, Takahiro Nishimichi, Masamune Oguri +4
While various observations measured ellipticities of galaxy clusters and alignments between orientations of the brightest cluster galaxies and their host clusters, there are only a…
Image Stacking Analysis of SDSS Galaxies with AKARI Far-Infrared Surveyor Maps at 65μm, 90μm, and 140μm
Taizo Okabe, Toshiya Kashiwagi, Yasushi Suto +4
We perform image stacking analysis of Sloan Digital Sky Survey (SDSS) photometric galaxies over the AKARI Far-Infrared Surveyor (FIS) maps at 65μm, 90μm, and 140μm. The resulting i…
