The frequency of very young galaxies in the local Universe: II. The view from SDSS spectra
Gary A. Mamon, Marina Trevisan, Trinh X. Thuan +2
Only a handful of galaxies in the local Universe appear to be very young. We estimate the fraction of very young galaxies (VYGs), defined as those with more than half their stellar…
Compact groups from semi-analytical models of galaxy formation -- I: a comparative study of frequency and nature
Eugenia Diaz-Gimenez, Antonela Taverna, Ariel Zandivarez +1
Compact groups (CGs) of galaxies are defined as isolated and dense galaxy systems that appear to be a unique site of multiple galaxy interactions. Semi-analytical models of galaxy…
ESA Voyage 2050 white paper -- Faint objects in motion: the new frontier of high precision astrometry
F. Malbet, U. Abbas, J. Alves +28
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Euclid preparation III. Galaxy cluster detection in the wide photometric survey, performance and algorithm selection
Euclid Collaboration, R. Adam, M. Vannier +56
Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe to test cosmological models. This method requires an efficient blind detection of clust…
Supernovae and their host galaxies -- VI. Normal Type Ia and 91bg-like supernovae in ellipticals
L. V. Barkhudaryan, A. A. Hakobyan, A. G. Karapetyan +4
We present an analysis of the galactocentric distributions of the "normal" and peculiar "91bg-like" subclasses of 109 supernovae (SNe) Ia, and study the global parameters of their…
Feedback by supermassive black holes in galaxy evolution: impacts of accretion and outflows on the star formation rate
Mojtaba Raouf, Joseph Silk, Stanislav S. Shabala +4
We describe a physical model of the outflows produced as a result of gas accretion onto a black hole, and the resultant changes to star formation rates and efficiencies in galaxies…
Structural and dynamical modeling of WINGS clusters. II. The orbital anisotropies of elliptical, spiral and lenticular galaxies
G. A. Mamon, A. Cava, A. Biviano +3
The Bayesian MAMPOSSt mass/orbit modeling algorithm is used to jointly fit the distribution of elliptical, spiral (and irregular), and lenticular galaxies in projected phase space,…
