Yule-Simpson's paradox in galactic archaeology
(Wiley Blackwell Publishing, Inc, 2019-05)
Simpson's paradox, or Yule-Simpson effect, arises when a trend appears in different subsets of data but disappears or reverses when these subsets are combined. We describe here seven cases of this phenomenon for chemo-kinematical ...
The Auriga stellar haloes: connecting stellar population properties with accretion and merging history
(2019)
We examine the stellar haloes of the Auriga simulations, a suite of 30 cosmological magnetohydrodynamical high-resolution simulations of Milky Way-mass galaxies performed with the moving-mesh code AREPO. We study halo ...
Ionized gas kinematics and luminosity profiles of Low-z Lyman Alpha Blobs
(Cambridge University Press, 2021-03)
This work is focused on the characterization of the Seyfert-2 galaxies hosting very large, ultra-luminous narrow-line regions (NLRs) at redshifts z = 0.2-0.34. With a space density of 4.4 Gcp-3 at z ∼0.3, these "Low Redshift ...
Comparing galaxy populations in compact and loose groups of galaxies III. Effects of environment on star formation
(EDP Sciences, 2015-01)
Aims. This paper is part of a series in which we systematically compare the properties of galaxies in compact groups, loose groups, and the field. In this paper we focus our study on the age and star formation in galaxies. ...
