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 ...
VALES VII. Molecular and ionized gas properties in the pressure balanced interstellar medium of starburst galaxies at z ∼ 0.15
(European Southern Observatory, 2020)
Context. Spatially resolved observations of the ionized and molecular gas are critical for understanding the physical processes that govern the interstellar medium (ISM) in galaxies. The observation of starburst systems ...
The colour-magnitude relation of simulated early-type galaxies as a function of their kinematics
(Asociación Argentina de Astronomía, 2021-07)
Early-type (ET) galaxies (both elliptical and lenticular) define the well-known red sequence or colour-magnitude relation (CMR) in the colour-magnitude diagram (CMD). In this work, we present results of the study of that ...
Spectroscopic study of the [OIII]λ5007 profile in Seyfert 1 galaxies
(Oxford Univ Press Inc, 2021-04)
The spectra of active galactic nuclei usually exhibit wings in some emission lines, such as [OIII]λλ5007,4959, with these wings generally being blueshifted and related to strong winds and outflows. The aim of this work was ...
High-speed stars: Galactic hitchhikers
(EDP Sciences, 2020-06)
Context. The search for stars born in the very early stages of the Milky Way star formation history is of paramount importance in the study of the early Universe since their chemistry carries irreplaceable information on ...
GHASP: an H alpha kinematic survey of spiral and irregular galaxies - IX. The near-infrared, stellar and baryonic Tully-Fisher relations
(WILEY-BLACKWELL, 2011)
We studied, for the first time, the near-infrared, stellar and baryonic Tully-Fisher relations for a sample of field galaxies taken from a homogeneous Fabry-Perot sample of galaxies [the Gassendi HAlpha survey of SPirals ...
The EDGE-CALIFA Survey: Molecular and Ionized Gas Kinematics in Nearby Galaxies
(IOP Publishing, 2018-06)
We present a comparative study of molecular and ionized gas kinematics in nearby galaxies. These results are based on observations from the EDGE survey, which measured spatially resolved 12CO(J = 1-0) in 126 nearby galaxies. ...
SDSS-IV MaNGA: a distinct mass distribution explored in slow-rotating early-type galaxies
(OXFORD UNIV PRESS, 2018)
We study the radial acceleration relation (RAR) for early-type galaxies (ETGs) in the SDSS MaNGA MPL5 data set. The complete ETG sample show a slightly offset RAR from the relation reported by McGaugh et al. (2016) at the ...
