Spiral structure of the third galactic quadrant and the solution to the Canis Major debate
(Wiley Blackwell Publishing, Inc, 2006-05)
With the discoveryofthe Sagittarius dwarf spheroidal, agalaxy caughtinthe processofmerging with the Milky Way, the hunt for other such accretion events has become a very active field of astrophysical research. The ...
The rest-frame optical (900nm) galaxy luminosity function at z∼4–7: abundance matching points to limited evolution in the MSTAR/MHALO ratio at z ≥ 4
(IOP Publishing Ltd., 2017)
We present the first determination of the galaxy luminosity function (LF) at z ∼4, 5, 6, and 7, in the rest-frame
optical at l ~ rest 900 nm (z′ band). The rest-frame optical light traces the content in low-mass evolved ...
Occurrence of LINER galaxies within the galaxy group environment
(Oxford University Press, 2017-05)
We study the properties of a sample of 3967 low-ionization nuclear emission-line region (LINER) galaxies selected from SDSS-DR7, with respect to their proximity to galaxy groups. The host galaxies of LINERs have been ...
Angular momentum evolution for galaxies in a Λ-CDM scenario
(EDP Sciences, 2015-12)
Context. Galaxy formation in the current cosmological paradigm is a verycomplex process in which inflows, outflows, interactions, and mergersare common events. These processes can redistribute the angular momentumcontent ...
Shapley Supercluster Survey: Galaxy evolution from filaments to cluster cores
(Royal Astronomical Society, 2015)
We present an overview of a multiwavelength survey of the Shapley Supercluster (SSC;
z ∼ 0.05) covering a contiguous area of 260 h
−2
70 Mpc2 including the supercluster core. The
project main aim is to quantify the ...
Populações estelares e gás ionizado em galáxias esferoidais centrais
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2019-07-10)
Central galaxies of dark matter massive halos, usually of spheroidal morphology, have distinct
physical properties of non-central spheroidal galaxies with comparable mass. Several studies
suggest that, because they are ...
The VANDELS survey: the ionizing properties of star-forming galaxies at 3 ≤ z ≤ 5 using deep rest-frame ultraviolet spectroscopy
(Oxford University Press, 2023-07-01)
The physical properties of Epoch of Reionization (EoR) galaxies are still poorly constrained by observations. To better understand the ionizing properties of galaxies in the EoR, we investigate deep, rest-frame ultraviolet ...
Satellites and central galaxies in SDSS: The influence of interactions on their properties
(Wiley Blackwell Publishing, Inc, 2021-02)
We use SDSS-DR14 to construct a sample of galaxy systems consisting of a central object and two satellites. We adopt projected distance and radial velocity difference criteria and impose an isolation criterion to avoid ...
