Compact near infrared sources in the center of the extraordinary galaxy IC 860

J. S. Gallagher, L. Schisgal, G. C. Privon +7

Hubble Space Telescope (HST) images are used to study the structure of the central regions of the luminous infrared galaxy (LIRG) IC 860. IC 860 is of special interest as a system…

Chemical complexity in star formation induced by stellar feedback: cores shock-formed by the supernova remnant W44

G. Cosentino, I. Jiménez-Serra, F. Fontani +8

Low-velocity shocks from Supernova Remnants (SNRs) may set the physical and chemical conditions of star formation in molecular clouds. Recent evidence suggests that the Sun might h…

CO Depletion in Infrared Dark Clouds

G. Cosentino, J. C. Tan, C. Gainey +10

Infrared Dark Clouds (IRDCs) are cold, dense structures representative of the initial conditions of star formation. Many studies of IRDCs employ CO to investigate cloud dynamics. H…

Low-velocity large-scale shocks in the infrared dark cloud G035.39-00.33: bubble-driven cloud-cloud collisions

G. Cosentino, I. Jiménez-Serra, R. Liu +7

Low-velocity large-scale shocks impacting on the ISM may efficiently shape molecular clouds and trigger star formation within them. These shocks, both driven by galactic bubbles an…

On unveiling Buried Nuclei with JWST: a technique for hunting the most obscured galaxy nuclei from local to high redshift

I. García-Bernete, F. R. Donnan, D. Rigopoulou +12

We analyze JWST NIRSpec+MIRI/MRS observations of the infrared (IR) Polycyclic Aromatic Hydrocarbon (PAH) features in the central regions (0.26'' at 6 micron; 50-440 pc…

An Imaging and Spectroscopic Exploration of the Dusty Compact Obscured Nucleus Galaxy Zw~049.057

J. S. Gallagher, R. Kotulla, L. Laufman +9

Zw~049.057 is a moderate mass, dusty, early-type galaxy that hosts a powerful compact obscured nucleus (CON, L10~L). The resolution of HST enabled…
