ALMAGAL IX. The chemical complexity of AG318.9477-00.1960: A line-identification template for ALMAGAL

J. Allande, M. T. Beltrán, V. M. Rivilla +36

We present a detailed molecular line analysis of one of the most chemically rich cores in the ALMAGAL sample, the high-mass core~9 in the AG318.9477-00.1960 clump (AG318-c9), locat…

A nine-member protostellar system forming via filament fragmentation in the high mass protocluster NGC 6334-43

D. J. Taylor, C. J. Cyganowski, C. L. Brogan +3

We present the serendipitous discovery of a nine-member system comprised of protostellar and candidate prestellar sources in 350 au-resolution images from Complex Chemistry i…

A millimeter methanol maser ring tracing the deceleration of the heat wave powered by the massive protostellar accretion outburst in G358.93-0.03 MM1

T. R. Hunter, C. L. Brogan, G. C. MacLeod +3

We present multi-epoch, multi-band ALMA imaging of the new Class II millimeter methanol masers excited during the accretion outburst of the massive protostar G358.93-0.03 MM1. The…

ALMAGAL V. Relations between the core populations and the parent clump physical properties

D. Elia, A. Coletta, S. Molinari +54

Context. The fragmentation of massive molecular clumps into smaller, potentially star-forming cores plays a key role in the processes of high-mass star formation. The ALMAGAL proje…

ALMAGAL IV. Morphological comparison of molecular and thermal dust emission using the histogram of oriented gradients (HOG) method

C. Mininni, S. Molinari, J. D. Soler +46

The study of molecular line emission is crucial to unveil the kinematics and the physical conditions of gas in star-forming regions. Our aim is to quantify the reliability of using…

CoCCoA: Complex Chemistry in hot Cores with ALMA. The chemical evolution of acetone from ice to gas

Y. Chen, R. T. Garrod, M. Rachid +5

Acetone (CH3COCH3) is one of the most abundant three-carbon oxygen-bearing complex organic molecules (O-COMs) that have been detected in space. Recently, acetone ice has been repor…
