Dynamical models of cluster members to probe the total mass properties of cluster subhalos. I. A comparison with parametric strong lensing models
Nicola Bianchetti, Claudio Grillo, Giovanni Granata +6
In this series of papers, we present dynamical models of cluster members in strong lensing (SL) galaxy clusters to independently probe the persistent discrepancy reported between S…
CLASH-VLT velocity anisotropy profiles in a stack of massive galaxy clusters
E. Maraboli, A. Biviano, C. Grillo +4
We measure the velocity anisotropy profile of different galaxy cluster member populations by analysing the stacked projected phase space of nine massive ($M_\mathrm{200c}>7…
Cosmology with supernova Encore in the strong lensing cluster MACS J01382155: photometry, cluster members, and lens mass model
S. Ertl, S. H. Suyu, S. Schuldt +23
The strongly lensed Supernova (SN) Encore at a redshift of , discovered behind the galaxy cluster MACS J01382155 at , provides a rare opportunity for time-de…
HOLISMOKES XIX: SN 2025wny at , the first strongly lensed superluminous supernova
Stefan Taubenberger, Ana Acebron, Raoul Cañameras +45
We present imaging and spectroscopic observations of supernova SN 2025wny, associated with the lens candidate PS1 J0716+3821. Photometric monitoring from the Lulin and Maidanak obs…
Is there a tilt in the fundamental (hyper)plane?
M. D'Addona, A. Mercurio, C. Grillo +18
We investigate the fundamental plane (FP) of selected early-type (ETG) member galaxies of the galaxy cluster PLCK G287.0+32.9 (), exploring also four-dimensional hy…
Galaxies at the edges: a complete census of MACS J0416.1-2403 cluster
Rossella Ragusa, Maurizio D'Addona, Amata Mercurio +20
Numerous studies have established that the environment influences the physical properties of a galaxy. While gas inflows supply the fuel for SF, high density and temperature condit…
