[O iii] 5007 Å Emission Line Width as a Surrogate for σ ∗ in Type 1 AGNs?

open access: yesThe Astrophysical Journal, 2023
We present a study of the relation between the [O iii ] 5007 Å emission line width ( σ _[O _III _] ) and stellar velocity dispersion ( σ _* ), utilizing a sample of 740 type 1 active galactic nuclei (AGNs) with high-quality spectra at redshift z < 1.0 ...

Blueberry galaxies: the lowest mass young starbursts

open access: yes, 2017
Searching for extreme emission line galaxies allows us to find low-mass metal-poor galaxies that are good analogs of high redshift Ly$\alpha$ emitting galaxies.

SHOCKED POSTSTARBUST GALAXY SURVEY. I. CANDIDATE POST-STARBUST GALAXIES WITH EMISSION LINE RATIOS CONSISTENT WITH SHOCKS [PDF]

open access: yes, 2016
There are many mechanisms by which galaxies can transform from blue, star-forming spirals, to red, quiescent early-type galaxies, but our current census of them does not form a complete picture.

Innovation for Sustainable Development: Assessing Sustainability‐Oriented Innovations in the UK Palm Oil Supply Chains

open access: yesSustainable Development, EarlyView.
ABSTRACT This research evaluates the adoption of Sustainability‐Oriented Innovations (SOIs) by UK food manufacturers, particularly in the palm oil sector. Despite the global palm oil industry's environmental and social impacts, such as deforestation and labour exploitation, empirical studies on SOIs are limited. This paper addressed this gap by mapping

The Lyman Continuum Escape Fraction of Emission Line-selected z ∼ 2.5 Galaxies Is Less Than 15% [PDF]

open access: yes, 2017
Recent work suggests that strong emission line, star-forming galaxies (SFGs) may be significant Lyman continuum leakers. We combine archival Hubble Space Telescope broadband ultraviolet and optical imaging (F275W and F606W, respectively) with emission ...

A patient‐derived orthotopic xenograft model unveils metastatic dynamics in head and neck squamous cell carcinoma

open access: yesThe FEBS Journal, EarlyView.
Metastasis in head and neck squamous cell carcinoma (HNSC) poses significant clinical challenges. This proof‐of‐concept study establishes patient‐derived orthotopic xenografts (PDOXs) as advanced models that closely replicate primary HNSC tumours, including local lymph node metastasis and the intricate cancer–stroma interaction.

Green Peas in the Southern Sky: Broadband Color Selection and Spectroscopic Follow-up

open access: yesThe Astrophysical Journal
We present a systematic search for 1696 green pea (GP) galaxy candidates in the southern hemisphere selected from the Dark Energy Survey Data Release 2 and provide preliminary results from spectroscopic follow-up observations of 26 targets chosen among ...

On the Nature of the Strong Emission-Line Galaxies in Cluster Cl 0024+1654: Are Some the Progenitors of Low Mass Spheroidals? [PDF]

open access: yes, 1997
We present new size, line ratio, and velocity width measurements for six strong emission-line galaxies in the galaxy cluster, Cl 0024+1654, at redshift z~0.4.

A translated utopia: Embodied communication, media ideologies, and Star Trek's Universal Translator

open access: yesJournal of Linguistic Anthropology, EarlyView.
Abstract This paper uses Star Trek's “Universal Translator” (UT) as a point of departure for considering the imagined future of mediated linguistic interactions and of contact across difference. Although such a technology does not exist, taking its potentialities seriously as folkloric devices allows for an exploration of ideologies relating to ...
