JWST Observations of Starbursts: A Young Bubble in NGC 253's Central Starburst

Kaitlyn E. Sheriff, Elisabeth A. C. Mills, Xinyu Mai +31

We present a multi-wavelength analysis of a young bubble in the nuclear starburst of NGC 253 using new JWST MIRI-MRS observations together with archival ALMA (100, 350, 690 GHz) an…

JWST Whirlpool Galaxy Treasury: Mid-Infrared Emission in M51 and its Relation to Gas Column and Star Formation

Mansi Padave, Karin M. Sandstrom, Daniel A. Dale +25

Using JWST/MIRI imaging of M51 in eight broadband filters, we investigate correlations of mid-infrared emission from polycyclic aromatic hydrocarbons (PAHs) and dust continuum with…

GA-NIFS and JADES: Confirmation of pristine gas near GN-z11

Hannah Übler, Roberto Maiolino, Pablo G. Pérez-González +32

According to the leading cosmological model, a first generation of stars called Population III (PopIII), condensed almost entirely out of hydrogen and helium, must have initiated t…

ReveaLLAGN 1: JWST Emission-Line Spectra Reveal Low-Luminosity AGN with UV-Deficient SEDs and Warm Molecular Gas

Kameron Goold, Anil Seth, Mallory Molina +20

We present near- and mid-infrared spectra of eight Low-Luminosity Active Galactic Nuclei (LLAGN), spanning nearly four orders of magnitude in black hole mass and Eddington ratio, o…

GA-NIFS: AGN activity in a Lyα emitter within a triple-AGN system anchored by a passive galaxy at z=3

Michele Perna, Santiago Arribas, Mahmoud Hamed +15

Massive quenched galaxies at z>3 challenge models of early galaxy evolution, as their rapid formation and abrupt quenching require efficient feedback, often linked to active galact…

GA-NIFS: Powerful and frequent outflows in moderate-luminosity active galactic nuclei at

Giacomo Venturi, Stefano Carniani, Elena Bertola +18

The period between z ~ 3-6, a key transformational phase in galaxy evolution preceding 'cosmic noon' (z ~ 1-3), is very poorly explored in terms of feedback from AGN acting through…
