X-Ray Polarized View on the Accretion Geometry in the X-Ray Binary Circinus X-1
John Rankin, Fabio La Monaca, Alessandro Di Marco +101
Cir X-1 is a neutron star X-ray binary characterized by strong variations in flux during its eccentric 16.6 days orbit. There are also strong variations in the spectral state…
Probing supermassive black hole growth and its dependence on stellar mass and star-formation rate in low-redshift galaxies
O. Torbaniuk, M. Paolillo, R. D'Abrusco +4
We present an improved study of the relation between supermassive black hole growth and their host galaxy properties in the local Universe (z < 0.33). To this end, we build an exte…
The He abundance in NGC 1850 A and B: are we observing the early stage of formation of multiple populations in a stellar cluster?
R. Carini, A. Sollima, E. Brocato +1
We present the result of a sample of B-stars in the Large Magellanic Cloud young double stellar cluster NGC 1850 A and NGC 1850 B, observed with the integral-field spectrograph at…
AMICO-COSMOS galaxy cluster and group catalogue up to : Sample properties and X-ray counterparts
Greta Toni, Matteo Maturi, Alexis Finoguenov +2
We present a new galaxy cluster search in the COSMOS field through the use of the Adaptive Matched Identifier of Clustered Objects (AMICO). We produced a new cluster and group cata…
The stellar mass function of quiescent galaxies in 2 < z < 2.5 protoclusters
Adit H. Edward, Michael L. Balogh, Yannick M. Bahe +21
We present an analysis of the galaxy stellar mass function (SMF) of 14 known protoclusters between in the COSMOS field, down to a mass limit of M$_{\odot…
Seismic and spectroscopic analysis of 9 bright red giants observed by Kepler
H. R. Coelho, A. Miglio, T. Morel +21
Photometric time series gathered by space telescopes such as CoRoT and Kepler allow to detect solar-like oscillations in red-giant stars and to measure their global seismic constra…
