SDSS-IV MaNGA: Spectroscopic Probes of Neutral Gas in Nearby Galaxies

The Astrophysical Journal
Cool, dusty interstellar material plays an important role in the chemical evolution of galaxies. We present an analysis of this material across galaxy type through a spatially resolved spectral stacking analysis of galaxies from the MaNGA survey.

Stellar mass and morphology segregation into pairs and multiplets in the cosmic web

Astronomy & Astrophysics
Aims. In this work, we investigate whether the location of galaxies within the large-scale structures (LSS) of the Universe leaves an imprint on their stellar mass (M★) and morphology. To this end, we attempt to disentangle the effects of local and large-

Exploring the star formation histories of galaxies [PDF]

, 1999
In this thesis, I explore the star formation histories of both spiral and elliptical galaxies. In Part 1,1 present an in-depth study of the star formation histories of spiral galaxies with a wide range of properties. Optical and near-infrared colours are

Modular training resources for bioimage analysis

Journal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

The CAVITY project

Astronomy & Astrophysics
The mass in the Universe is distributed non-uniformly, leading to the large scale structure (LSS), characterised by clusters, filaments, walls, and voids.

An infrared study of a sample of optically selected galaxies [PDF]

, 1987
Infrared and optical photometry of a complete sub-sample of 194 galaxies in the Anglo-Australian Redshift Survey is presented. The Colour-Redshift diagrams are constructed and used, in a self-consistent manner, to reduce the data to zero-redshift colours

Bioimage management and analysis in Galaxy: Tools, workflows, training, and community practices

Journal of Microscopy, EarlyView.
ABSTRACT Image analysis in the life sciences is constrained by fragmented software ecosystems, heterogeneous data formats, and limited reproducibility. These barriers hinder the reuse of image analysis methods and the sustainability of tools. In this article, we describe how the Galaxy platform enables FAIR (Findable, Accessible, Interoperable, and ...

Luminosity Evolution of the Hot Gas in Normal Galaxies from the Near Universe to z = 0.5

The Astrophysical Journal
We explore the evolution of the ∼10 ^7 K hot gas in normal galaxies out to redshift = 0.5 (lookback time = 5 Gyr), using X-ray luminosity functions (XLFs) built from a sample of 575 normal galaxies with z < 0.6 detected in five high-galactic-latitude ...
