Modified T 2 Control Chart of Principal Components When KDR and TSR Methods of Score Estimation are Used in Phase II

Julia Fernández, José Alberto Pagura, Marta Beatriz Quaglino

ABSTRACT When Phase II multivariate process control is performed using the chart of principal components and missing data occurs, KDR and TSR imputation methods allow for the calculation of the statistic. However, Hotelling's chart's performance has been shown to be affected by …

The critical human pathogen Acinetobacter baumannii exhibits light-regulated circadian rhythms

Valentín Permingeat, Bárbara Pérez Mora, María Laura Migliori, Natalia Arana et autres

Acinetobacter baumannii is recognized as the paradigm of multidrug-resistant superbug, topping the WHO priority list of critical human pathogens. Interestingly, it senses and responds to blue light, which modulates global aspects of its physiology, including pathogenicity. We hypothesized that light could serve …

A catalog of ringed galaxies in the TNG50 simulation: Analysis of their properties and structure

Julia Fernández, Emanuel Sillero, Sol Alonso, Patricia Beatriz Tissera

The catalog of ringed galaxies was compiled through visual classification of synthetic images from the TNG50 simulation. Galaxies were selected based on specific criteria: a redshift range of $0.01 < z < 0.1$, stellar mass $M_\star >10^9 M_\odot$, stellar half-mass radius $r_{50} …

Revealing ringed galaxies in group environments

Julia Fernández, Sol Alonso, Valeria Mesa, Fernanda Duplancic

Aims. We explore galaxies with ringed structures inhabiting poor and rich groups with the aim of assessing the effects of local density environments on ringed galaxy properties. Methods. We identified galaxies with inner, outer, nuclear, inner+outer (inner and outer rings combined), and …

Enlightening the Universe behind the Milky Way bulge

Fernanda Duplancic, Sol Alonso, Georgina Coldwell, Daniela Galdeano et autres

Context. The location of the Solar System complicates the detection extragalactic sources beyond the Milky Way plane. The optical observations are hampered in the so-called zone of avoidance (ZOA), where stellar crowding and Galactic absorption are severe. Observations at longer wavelengths are …

Enlightening the Universe behind the Milky Way Bulge

Fernanda Duplancic, Sol Alonso, Georgina Coldwell, Daniela Galdeano et autres

Context. The location of the Solar System constrains the detection of extragalactic sources beyond the Milky Way(MW) plane. The optical observations are hampered in the so--called Zone of Avoidance (ZOA) where stellar crowding and Galactic absorption are severe. Observations at longer wavelengths …

Properties of galaxies with ring structures

Julia Fernández, Sol Alonso, Valeria Mesa, Fernanda Duplancic et autres

Aims. We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods. We built a catalog of ringed galaxies from the Sloan Digital Sky Survey Data Release …
