Interpreting Millimeter Emission from IMEGIN galaxies NGC 2146 and NGC 2976
G. Ejlali, F. S. Tabatabaei, H. Roussel +59
The millimeter continuum emission from galaxies provides important information about cold dust, its distribution, heating, and role in their InterStellar Medium (ISM). This emissio…
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…
Improving constraints on the extended mass distribution in the Galactic Center with stellar orbits
The GRAVITY Collaboration, Karim Abd El Dayem, Roberto Abuter +66
Studying the orbital motion of stars around Sagittarius A* in the Galactic Center provides a unique opportunity to probe the gravitational potential near the supermassive black hol…
Assessing realistic binding energies of some essential interstellar radicals with amorphous solid water. A fully quantum chemical approach
Milan Sil, Arghyadeb Roy, Prasanta Gorai +6
In the absence of laboratory data, state-of-the-art quantum chemical approaches can provide estimates of the binding energy (BE) of interstellar species with grains. Without BE val…
Cosmic-ray induced sputtering of interstellar formaldehyde ices
M. Faure, A. Bacmann, A. Faure +4
H2CO is a ubiquitous molecule in the ISM and in the gas phase of prestellar cores, and is likely present in ice mantles, but its main desorption mechanism is unknown. In this paper…
Probing the Physics of Star-Formation (ProPStar) III. No evidence for dissipation of turbulence down to 20 mpc (4 000 au) scale
Jaime E. Pineda, Juan D. Soler, Stella Offner +14
Context. Turbulence is a key component of molecular cloud structure. It is usually described by a cascade of energy down to the dissipation scale. The power spectrum for subsonic i…
X-ray observations of Blueberry galaxies
B. Adamcová, J. Svoboda, E. Kyritsis +7
Compact star-forming galaxies were dominant galaxy types in the early Universe. Blueberry galaxies (BBs) represent their local analogues being very compact and having intensive sta…
