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…
ALMA CO(3-2) Observations of Star-Forming Filaments in a Gas-Poor Dwarf Spheroidal Galaxy
S. Michelle Consiglio, Jean L. Turner, Sara Beck +3
We report ALMA observations of CO(3-2) and CO(3-2) in the gas-poor dwarf galaxy NGC 5253. These 0.3"(5.5 pc) resolution images reveal small, dense molecular gas cloud…
ALMA Detects CO(3-2) within a Super Star Cluster in NGC5253
J. L. Turner, S. M. Consiglio, S. C. Beck +5
We present observations of CO(3-2) and CO(3-2) emission near the supernebula in the dwarf galaxy NGC 5253, which contains one of the best examples of a potential globular cl…
ALMA Reveals Potential Localized Dust Enrichment from Massive Star Clusters in II Zw 40
S. Michelle Consiglio, Jean L. Turner, Sara Beck +1
We present subarcsecond images of submillimeter CO and continuum emission from a local galaxy forming massive star clusters: the blue compact dwarf galaxy II Zw 40. At 0.4" r…
Highly efficient star formation in NGC 5253 possibly from stream-fed accretion
J. L. Turner, S. C. Beck, D. J. Benford +5
A local dwarf galaxy, NGC 5253, has a young super star cluster that may provide an example of highly efficient star formation. Here we report the detection and imaging, with the Su…
A Tight Connection between Gamma-Ray Outbursts and Parsec-Scale Jet Activity in the Quasar 3C 454.3
Svetlana G. Jorstad, Alan P. Marscher, Paul S. Smith +42
We analyze the multifrequency behavior of the quasar 3C 454.3 during three prominent γ-ray outbursts: 2009 Autumn, 2010 Spring, and 2010 Autumn. The data reveal a repeating pattern…
Ionized Gas in the First 10 Kiloparsecs of the Interstellar Galactic Halo: Metal Ion Fractions
J. Christopher Howk, S. Michelle Consiglio
We present direct measures of the ionization fractions of several sulfur ions in the Galactic warm ionized medium (WIM). We obtained high resolution ultraviolet absorption line spe…
