Resolved star-forming line-classification probability deficits in barred MaNGA galaxies

Astronomy & Astrophysics
Context. Stellar bars can drive gas inflow, shocks, radial mixing, and central mass growth, so they should leave measurable signatures in resolved optical emission-line excitation.

Emission-line Diagnostics at z > 4: [O iii]λ4364/Hγ versus [Ne iii]λ3870/[O ii]λ3730

The Astrophysical Journal
We use JWST Near-Infrared Spectrograph observations from the Cosmic Evolution Early Release survey, GLASS-JWST ERS (GLASS), and JWST Advanced Deep Extragalactic Survey to measure rest-frame optical emission-line ratios of 89 galaxies at z  > 4.

Resolving double-peaked emission line galaxies using MaNGA: I. Mechanisms of star formation quenching

International audienceUnderstanding the relationship between quenching mechanisms that transform star-forming galaxies into quiescent ones and galaxy properties remains a challenge.

The clustering of galaxies in hierarchical galaxy formation models [PDF]

, 2010
Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

Resolving the molecular gas emission of the z ∼ 2.5–2.8 starburst galaxies SPT 0125-47 and SPT 2134-50

Astronomy & Astrophysics
Context. The comoving cosmic star formation rate density peaks at z ∼ 2–3, with dusty star-forming galaxies being significant contributors to this peak.

Shining a Light on the Connections between Galactic Outflows Seen in Absorption and Emission Lines

The Astrophysical Journal
Galactic outflows provide important feedback effects to regulate the evolution of host galaxies. Two primary diagnostics of outflows are broad and/or blueshifted emission and absorption lines.

Predicting CO and dust emission of star-forming galaxies

Astronomy & Astrophysics
In this work, we investigate whether dwarf galaxies differ from spirals and whether star formation produces radio and far-infrared (FIR) emission in the same way as it does for spiral galaxies.
