Molecular chemistry induced by J-shock toward supernova remnant W51C
Tian-Yu Tu, Valentine Wakelam, Yang Chen +2
Shock waves from supernova remnants (SNRs) have strong influence on the physical and chemical properties of molecular clouds (MCs). Shocks propagating into magnetized MCs can be cl…
Kinetic Study of the Reactions of Ground State Atomic Carbon and Oxygen with Nitrogen Dioxide over the 50-296 K Temperature Range
Kevin M. Hickson, Jean-Christophe Loison
The kinetics of the reactions of nitrogen dioxide, NO, with atomic oxygen and atomic carbon in their ground triplet states (P) have been studied at room temperature and bel…
Predicting HCN, HCO, multi-transition CO, and dust emission of star-forming galaxies -- Extension to luminous infrared galaxies and the role of cosmic ray ionization
B. Vollmer, J. Freundlich, P. Gratier +4
The specific star-formation rate of star-forming `main sequence' galaxies significantly decreased since z~1.5, due to the decreasing molecular gas fraction and star formation effic…
Toward a robust physical and chemical characterization of heterogeneous lines of sight: The case of the Horsehead nebula
Léontine Ségal, Antoine Roueff, Jérôme Pety +28
Dense cold molecular cores/filaments are surrounded by an envelope of translucent gas. Some of the low-J emission lines of CO and HCO isotopologues are more sensitive to the co…
Gas phase Elemental abundances in Molecular cloudS (GEMS). X. Observational effects of turbulence on the chemistry of molecular clouds
L. Beitia-Antero, A. Fuente, D. Navarro-Almaida +12
(Abridged) We explore the chemistry of the most abundant C, O, S, and N bearing species in molecular clouds, in the context of the IRAM 30 m Large Programme Gas phase Elemental abu…
ALMA-IMF XVIII: The assembly of a star cluster: Dense NH (1-0) kinematics in the massive G351.77 protocluster
N. A. Sandoval-Garrido, A. M. Stutz, R. H. Álvarez-Gutiérrez +20
ALMA-IMF observed 15 massive protoclusters capturing multiple spectral lines and the continuum emission. We focus on the G351.77 protocluster ( 2500 M, estimated fr…
Quantifying the informativity of emission lines to infer physical conditions in giant molecular clouds. I. Application to model predictions
Lucas Einig, Pierre Palud, Antoine Roueff +29
Observations of ionic, atomic, or molecular lines are performed to improve our understanding of the interstellar medium (ISM). However, the potential of a line to constrain the phy…
SCOTCH Search for Clandestine Optically Thick Compact HII regions II
A. L. Patel, J. S. Urquhart, A. Y. Yang +4
In this study we present 18 to 24 GHz and high angular resolution radio wavelength Australia Telescope Compact Array follow up observations towards a sample of 39 HC HII region can…
Euclid: The Early Release Observations Lens Search Experiment
J. A. Acevedo Barroso, C. M. O'Riordan, B. Clément +206
We investigated the ability of the Euclid telescope to detect galaxy-scale gravitational lenses. To do so, we performed a systematic visual inspection of the Eucl…
ALMA-IMF XV: The core mass function in the high-mass star-formation regime
F. Louvet, P. Sanhueza, A. Stutz +38
The stellar initial mass function (IMF) is critical to our understanding of star formation and the effects of young stars on their environment. On large scales, it enables us to us…
Herschel Gould Belt Survey in Taurus. II: A census of dense cores and filaments in the TMC1 region
Jason Kirk, Derek Ward-Thompson, James Di Francesco +12
We present a catalogue of dense cores and filaments in a field around the TMC1 region of the Taurus Molecular Cloud. The catalogue was created using…
Euclid: Early Release Observations -- Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
J. -C. Cuillandre, M. Bolzonella, A. Boselli +199
The Euclid ERO programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7 square degree, corresponding to approximately 0…
Chemical inventory of the envelope of the Class I protostar L1551 IRS 5
P. Marchand, A. Coutens, J. Scigliuto +5
Episodic accretion in protostars leads to luminosity outbursts that end up heating their surroundings. This rise in temperature pushes the snow lines back, enabling the desorption…
A Low Temperature Kinetic Study of the C(3P) + CH3OCH3 Reaction. Rate constants, H-atom Product Yields and Astrochemical Implications
Kevin M. Hickson, Jean-Christophe Loison, Valentine Wakelam
Atomic carbon in its ground electronic state, C(3P), is expected to be present at high abundances during the evolution of dense molecular clouds. Consequently, its reactions with o…
First detection of the [CII] 158 micron line in the intermediate-velocity cloud Draco
N. Schneider, V. Ossenkopf-Okada, E. Keilmann +7
High-latitude intermediate-velocity clouds (IVCs) are part of the Milky Way's HI halo and originate from either a galactic fountain process or extragalactic gas infall. They are pa…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
