Measure of Solar oscillations and supergranulation with Magnetic-Optical Filter
I. Formicola, A. Longobardo, C. Pinto +1
Helioseismology is the branch of the Solar Physics which studies the solar global oscillations, a phenomenon very important in order to understand the inside of the Sun. We explain…
Bars in early- and late-type disks in COSMOS
E. Cameron, C. M. Carollo, P. Oesch +20
We investigate the (large-scale) bar fraction in a mass-complete sample of M > 10^10.5 Msun disk galaxies at 0.2 < z < 0.6 in the COSMOS field. The fraction of barred disks strongl…
Larger sizes of massive quiescent early-type galaxies in clusters than in the field at 0.8 < z < 1.5
L. Delaye, M. Huertas-Company, S. Mei +13
[abridged] The mass-size relation of early-type galaxies (ETGs) has been largely studied in the last years to probe the mass assembly of the most massive objects in the Universe. I…
A phylogenetic analysis of galaxies in the Coma Cluster and the field: a new approach to galaxy evolution
M. MartÃnez-MarÃn, R. Demarco, G. Cabrera-Vives +3
We propose a phylogenetic approach (PA) as a novel and robust tool to detect galaxy populations (GPs) based on their chemical composition. The branches of the tree are interpreted…
The Evolution of Brightest Cluster Galaxies in the Nearby Universe II: The star-formation activity and the Stellar Mass from Spectral Energy Distribution
G. Orellana-González, P. Cerulo, G. Covone +4
We study the star-formation activity in a sample of 56,000 brightest cluster galaxies (BCGs) at using optical and infra-red data from SDSS and WISE. We est…
Galaxy population properties of the massive X-ray luminous galaxy cluster XDCP J0044.0-2033 at z=1.58: red-sequence formation, massive galaxy assembly, and central star formation activity
R. Fassbender, A. Nastasi, J. S. Santos +20
We investigate various galaxy population properties of the massive X-ray luminous galaxy cluster XDCP J0044.0-2033 at z=1.58, which constitutes the most extreme matter density peak…
The GOGREEN survey: the internal dynamics of clusters of galaxies at redshift 0.9-1.4
A. Biviano, R. F. J. van der Burg, M. L. Balogh +20
We aim to determine the mass, velocity anisotropy, and pseudo phase-space density profiles (M(r), beta(r), and Q(r), respectively) of clusters of galaxies at the highest redshifts…
The importance of major mergers in the build up of stellar mass in brightest cluster galaxies at z=1
C. Lidman, G. Iacobuta, A. E. Bauer +22
Recent independent results from numerical simulations and observations have shown that brightest cluster galaxies (BCGs) have increased their stellar mass by a factor of almost two…
Tracing the Quenching History in Galaxy Clusters in the EAGLE Simulation
Diego Pallero, Facundo A. Gómez, Nelson D. Padilla +4
We use the EAGLE hydrodynamical simulation to trace the quenching history of galaxies in its 10 most massive clusters. We use two criteria to identify moments when galaxies suffer…
