Stellar Populations with MaNGA: Iron Kink and Nitrogen Fuzz

The Astrophysical Journal
Recent analysis of 2968 MaNGA early-type galaxies has yielded two notable trends with velocity dispersion ( σ ) not previously discussed in the literature. First, Fe abundance rises with σ but only until σ  ≈ 100 km s ^−1 , after which it falls.

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Radial Gradients and Intrinsic Scatter in MaNGA Galaxies

The Astrophysical Journal Supplement Series
We derive stellar population parameters and radial gradients within 0.65 R _e for spatially resolved spectra of 2968 early-type galaxies from MaNGA, spanning stellar velocity dispersions ( σ ) of 50–340 km s ^−1 .

Integral-Field Spectroscopy of High-Redshift Galaxies: Implications for Early Galaxy Evolution [PDF]

, 2006
Several lines of evidence suggest that the most active phase of galaxy evolution, especially in the most massive systems, was largely completed by $z\sim 1$.

Episodic Star Formation. I. Overview and Scatter of the Star-forming Main Sequence

The Astrophysical Journal
There is mounting evidence for episodic star formation cycles in both high- and low-redshift galaxies. This paper aims to understand the detailed physical processes behind such behaviors and investigate how such an episodic star-forming scenario can ...

MUC1 as a Survival Effector of Radiotherapy‐Induced Epithelial Hybrid States in Basal‐Like Breast Cancer

International Journal of Cancer, EarlyView.
Basal‐like breast cancer (BLBC) is aggressive and often exhibits inherent or acquired resistance to radiotherapy (RT), a primary treatment option. RT resistance is underpinned by molecular alterations, many of which are poorly understood. Here, RT‐induced transcriptomic changes were analyzed using bulk and spatial sequencing in a BLBC mouse model and ...

Attitudes and behaviours of consumers towards plant‐based yoghurt alternatives: a cross‐cultural study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Increased awareness of sustainable food production and vegan, vegetarian and flexitarian diets are driving the growth in dairy substitutes, particularly plant‐based yoghurts. To understand consumer perception or mind‐set and facilitate adoption of plant‐based yoghurt products, a multi‐phase study using both qualitative and ...

Modeling the Ages and Chemical Abundances of Elliptical Galaxies

The Astrophysical Journal
Spectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and α enhancement traced by [Mg/Fe] all increase with galaxy stellar mass or velocity dispersion.

Secondary evolution of galaxies investigated by N-body simulations

, 2008
In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...
