Blooming Trees: Substructures and Surrounding Groups of Galaxy Clusters
Heng Yu, Antonaldo Diaferio, Ana Laura Serra +1
We develop the Blooming Tree Algorithm, a new technique that uses spectroscopic redshift data alone to identify the substructures and the surrounding groups of galaxy clusters, alo…
Variegate galaxy cluster gas content: Mean fraction, scatter, selection effects and covariance with X-ray luminosity
S. Andreon, J. Wang, G. Trinchieri +2
We use a cluster sample selected independently of the intracluster medium content with reliable masses to measure the mean gas mass fraction and its scatter, the biases of the X-ra…
The mass accretion rate of galaxy clusters: a measurable quantity
Cristiano De Boni
We are interested in investigating the growth of structures at the nonlinear scales of galaxy clusters from an observational perspective: we explore the possibility of measuring th…
The amazing diversity in the hot gas content of an X-ray unbiased massive galaxy clusters sample
S. Andreon, A. L. Serra, A. Moretti +1
We aim to determine the intrinsic variety, at a given mass, of the properties of the intracluster medium in clusters of galaxies. This requires a cluster sample selected independen…
Identification of galaxy cluster substructures with the Caustic method
Heng Yu, Ana Laura Serra, Antonaldo Diaferio +1
We investigate the power of the caustic technique for identifying substructures of galaxy clusters from optical redshift data alone. The caustic technique is designed to estimate t…
GLACE survey: OSIRIS/GTC Tuneable Filter H imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z = 0.395. Part I -- Survey presentation, TF data reduction techniques and catalogue
Miguel Sánchez-Portal, Irene Pintos-Castro, Ricardo Pérez-Martínez +35
The cores of clusters at 0 z 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type ones. Galaxy propertie…
The mass accretion rate of galaxy clusters: a measurable quantity
Cristiano De Boni, Ana Laura Serra, Antonaldo Diaferio +2
We explore the possibility of measuring the mass accretion rate (MAR) of galaxy clusters from their mass profiles beyond the virial radius . We derive the accretion rate f…
Deep spectroscopic luminosity function of Abell 85: no evidence for a steep upturn of the faint-end slope
I. Agulli, J. A. L. Aguerri, R. Sánchez-Janssen +4
We present a new deep determination of the spectroscopic LF within the virial radius of the nearby and massive Abell\,85 (A85) cluster down to the dwarf regime (M* + 6) using VLT/V…
The radial metallicity gradients in the Milky Way thick disk as fossil signatures of a primordial chemical distribution
A. Curir, A. L. Serra, A. Spagna +3
In this letter we examine the evolution of the radial metallicity gradient induced by secular processes, in the disk of an -body Milky Way-like galaxy. We assign a [Fe/H] value…
Identification of members in the central and outer regions of galaxy clusters
Ana Laura Serra, Antonaldo Diaferio
The caustic technique measures the mass of galaxy clusters in both their virial and infall regions and, as a byproduct, yields the list of cluster galaxy members. Here we use 100 g…
Measuring the Mass Distribution in Galaxy Clusters
Margaret J. Geller, Antonaldo Diaferio, Kenneth J. Rines. Ana Laura Serra
Cluster mass profiles are tests of models of structure formation. Only two current observational methods of determining the mass profile, gravitational lensing and the caustic tech…
Measuring the dark matter equation of state
Ana Laura Serra, Mariano Javier de León Domínguez Romero
The nature of the dominant component of galaxies and clusters remains unknown. While the astrophysics community supports the cold dark matter (CDM) paradigm as a clue factor in the…
Measuring the escape velocity and mass profiles of galaxy clusters beyond their virial radius
Ana Laura Serra, Antonaldo Diaferio, Giuseppe Murante +1
The caustic technique uses galaxy redshifts alone to measure the escape velocity and mass profiles of galaxy clusters to clustrocentric distances well beyond the virial radius, whe…
Implications for dwarf spheroidal mass content from interloper removal
Ana Laura Serra, Garry W. Angus, Antonaldo Diaferio
Using the caustic method, we identify the member stars of five dwarf spheroidal (dSph) galaxies of the Milky Way, the smallest dark matter (DM) dominated systems in the Universe. A…
