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…

A search for the first galaxies across deg of JWST imaging: new evidence for a rapid decline in star-formation activity at

D. J. McLeod, J. S. Dunlop, R. J. McLure +20

We present a new determination of the evolving galaxy UV luminosity function (LF) over the extreme redshift range , based on a wide-area search of 0.6 deg of JW…

Detection of CO ice in the planetary nebula NGC 6302

Charmi Bhatt, Simon W. Cao, Jan Cami +20

Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…

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…

A compact Keplerian-like disc and H30 emission towards the radio jet in the massive protostar W75N(B)-VLA3

A. Sanchez-Monge, J. F. Gomez, J. M. Torrelles +13

Studying young, high-mass stellar objects is challenging for testing models of massive star formation due to their great distances, often kiloparsecs away. This requires extremely…
