A possible formation scenario for dwarf spheroidal galaxies - I. Fiducial model
(2013-06)
We perform numerical simulations to study a formation scenario for dwarf spheroidal (dSph) galaxies in which their stellar populations are the products of the dissolution of open star clusters and stellar associations ...
Structural Performance of Bridges in the Offshore Maule Earthquake of 27 February 2010
(EARTHQUAKE ENGINEERING RESEARCH INST, 2012)
Of the nearly 12,000 highway bridges in Chile, approximately 300 were damaged in this earthquake, including 20 with collapsed spans. Typical failure modes include damage to connections between super- and substructures, ...
The Gaia-ESO Survey: a quiescent Milky Way with no significant dark/stellar accreted disc(a similar to...)
(OXFORD UNIV PRESS, 2015)
According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will be dragged towards the disc plane, ...
Molecules with ALMA at Planet-forming Scales (MAPS). XVIII. Kinematic Substructures in the Disks of HD 163296 and MWC 480
(IOP, 2021)
We explore the dynamical structure of the protoplanetary disks surrounding HD 163296 and MWC 480 as part of the Molecules with ALMA at Planet-forming Scales (MAPS) large program. Using the J = 2-1 transitions of (CO)-C-12, ...
The Gaia -ESO survey: separating disk chemical substructures with cluster models∗: evidence of a separate evolution in the metal-poor thin disk
(EDP Sciences, 2016-02)
Context. Recent spectroscopic surveys have begun to explore the Galactic disk system on the basis of large data samples, with spatial
distributions sampling regions well outside the solar neighborhood. In this way, they ...
Weak-lensing mass distributions for 24 X-ray Abell clusters
(UNIV CHICAGO PRESS, 2004-09-20)
We use the weak gravitational lensing effect to study the mass distribution and dynamical state of a sample of 24 X-ray-luminous clusters of galaxies (0.05 < z < 0.31) observed with the FORS1 instrument mounted on the ...
The immunogenetic diversity of the HLA system in Mexico correlates with underlying population genetic structure
(Elsevier Science Inc, 2020-09)
We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) allele groups and alleles by PCR-SSP based typing in a total of 15,318 mixed ancestry Mexicans from all the states of the country divided into 78 sample ...
Hα emission observations of nearby baryonic structures
(2022)
A fundamental question in astronomy is how the environment affects galaxy evolution. Baryonic structures in the nearby universe can be used as laboratories to study the influence of the environment on galaxy evolution ...
