JWST View of the Supernebula in NGC 5253. II. Nebular Lines

Sara C. Beck, Jean L. Turner, Elm Zweig +7

The nearby dwarf starburst NGC 5253 is dominated by a compact radio-infrared supernebula powered by a very young and bright embedded Super Star Cluster (SSC) of …

JWST View of the Supernebula in NGC 5253. I. Overview and Continuum Features

Jean L. Turner, Sara C. Beck, Elm A. Zweig +7

We present 5-28m imaging spectroscopy of the "supernebula" in the dwarf galaxy NGC 5253 made with the JWST MIRI-MRS integral field spectrometer. NGC 5253 hosts a luminous ($L\si…

The Radio-Infrared Nebula in II Zw 40: Clusters Forming in Colliding Elongated Clouds

Dan Beilis, Sara Beck, John Lacy +4

II Zw 40 is a starburst dwarf and merger product, and holds a radio-infrared supernebula excited by thousands of embedded OB stars. We present here observations of three aspects of…

Observing the influence of the youngest super star clusters in NGC 1569: Keck Brackett spectroscopy

Daniel P. Cohen, Jean L. Turner, Sara C. Beck +1

We report Keck-NIRSPEC observations of the Brackett 4.05 m recombination line across the two candidate embedded super star clusters (SSCs) in NGC 1569. These SSCs power a br…

Unveiling Kinematic Structure in the Starburst Heart of NGC 253

Daniel P. Cohen, Jean L. Turner, S. Michelle Consiglio

We investigate the kinematics of ionized gas within the nuclear starburst of NGC 253 with observations of the Brackett recombination line at 4.05 m. The goal is to distingui…

Ionized Gas Motions and the Structure of Feedback Near a Forming Globular Cluster in NGC 5253

Daniel P. Cohen, Jean L. Turner, S. Michelle Consiglio +2

We observed Brackett 4.05m emission towards the supernebula in NGC 5253 with NIRSPEC on Keck II in adaptive optics mode, NIRSPAO, to probe feedback from its exciting embedde…
