Thermal imaging of dust hiding the black hole in the Active Galaxy NGC 1068
Violeta Gamez Rosas, Jacob W. Isbell, Walter Jaffe +49
In the widely accepted 'Unified Model' solution of the classification puzzle of Active Galactic Nuclei, the orientation of a dusty accretion torus around the central black hole dom…
ALMA-IMF I -- Investigating the origin of stellar masses: Introduction to the Large Program and first results
F. Motte, S. Bontemps, T. Csengeri +61
The ALMA-IMF Large Program imaged a total noncontiguous area of 53pc2, covering 15 extreme, nearby protoclusters of the Milky Way. They were selected to span relevant early protocl…
Organic chemistry in the protosolar analogue HOPS-108: Environment matters
L. Chahine, A. López-Sepulcre, R. Neri +10
Hot corinos are compact regions around solar-mass protostellar objects that are very rich in interstellar complex organic molecules (iCOMs). They are believed to represent the very…
The Spatial Evolution of Young Massive Clusters III. Effect of the Gaia Filter on 2D Spatial Distribution Studies
Anne S. M. Buckner, Zeinab Khorrami, Marta González +3
[Context.] Gaia is limited in the optical down to G~21 mag so it is essential to understand the biases introduced by a magnitude-limited sample on spatial distribution studies. [Ai…
The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits
GRAVITY Collaboration, R. Abuter, N. Aimar +62
The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…
Deep Images of the Galactic Center with GRAVITY
GRAVITY Collaboration, R. Abuter, N. Aimar +65
Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond th…
On the rise times in FU Orionis events
Elisabeth M. A. Borchert, Daniel J. Price, Christophe Pinte +1
We examine whether stellar flyby simulations can initiate FU Orionis outbursts using 3D hydrodynamics simulations coupled to live Monte Carlo radiative transfer. We find that a fly…
Galactic Star Formation with NIKA2 (GASTON): Evidence of mass accretion onto dense clumps
A. J. Rigby, R. Adam, P. Ade +49
High-mass stars () play a crucial role in the evolution of galaxies, and so it is imperative that we understand how they are formed. We have used the New…
Expanding the submillimeter wave spectroscopy and astronomical search for thioacetamide (CH3CSNH2) in the ISM
A. Remijan, C. Xue, L. Margulès +12
Thioacetamide (CH3CSNH2) is the sulfur analog to acetamide (CH3CONH2) and it is a viable candidate to search for in astronomical environments specifically toward regions where othe…
Sulfur gas-phase abundance in dense cores
P. Hily-Blant, G. Pineau des Forêts, A. Faure +1
The abundance of volatile sulfur in dense clouds is long-standing problem in studies of the physics and chemistry of star-forming regions. Sulfur is an important species because it…
Collisional excitation and non-LTE modelling of interstellar chiral propylene oxide
K. Dzenis, A. Faure, B. A. McGuire +7
The first set of theoretical cross sections for propylene oxide (CH3CHCH2O) colliding with cold He atoms has been obtained at the full quantum level using a high-accuracy potential…
ALMA-IMF II -- investigating the origin of stellar masses: Continuum Images and Data Processing
A. Ginsburg, T. Csengeri, R. Galván-Madrid +49
We present the first data release of the ALMA-IMF Large Program, which covers the 12m-array continuum calibration and imaging. The ALMA-IMF Large Program is a survey of fifteen den…
A SPHERE survey of self-shadowed planet-forming disks
A. Garufi, C. Dominik, C. Ginski +20
To date, nearly two hundred planet-forming disks have been imaged with high resolution. Our propensity to study bright and extended objects is however biasing our view of the disk…
Sampling Molecular Gas in the Helix Planetary Nebula: Variation in HNC/HCN with UV Flux
Jesse Bublitz, Joel H. Kastner, Pierre Hily-Blant +4
Observations of molecular clouds, prestellar cores, and protoplanetary disks have established that the HNC/HCN ratio may be a potent diagnostic of molecular gas physical conditions…
Dust Emission in Galaxies at Millimeter Wavelengths: Cooling of star forming regions in NGC6946
G. Ejlali, R. Adam, P. Ade +54
Interstellar dust plays an important role in the formation of molecular gas and the heating and cooling of the interstellar medium. The spatial distribution of the mm-wavelength du…
Galactic star formation with NIKA2 (GASTON): Filament convergence and its link to star formation
N. Peretto, R. Adam, P. Ade +45
In the past decade filaments have been recognised as a major structural element of the interstellar medium, the densest of these filaments hosting the formation of most stars. In s…
Overdensity of SubMillimiter Galaxies in the GJ526 Field mapped with the NIKA2 Camera
J. -F. Lestrade, R. Adam, P. Ade +43
Using the NIKA2 dual band millimeter camera installed on the IRAM30m telescope, we have mapped a relatively large field (~70 arcmin^2) in the direction of the star GJ526 to investi…
Exploring the millimetre emission in nearby galaxies: analysis of the edge-on galaxy NGC 891
S. Katsioli, R. Adam, P. Ade +54
New observations of the edge-on galaxy NGC 891, at 1.15 and 2 mm obtained with the IRAM 30-m telescope and the NIKA2 camera, within the framework of the IMEGIN (Interpreting the Mi…
ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT) VI: Accretion shocks in the disk of DG Tau and HL Tau
A. Garufi, L. Podio, C. Codella +9
Planet-forming disks are not isolated systems. Their interaction with the surrounding medium affects their mass budget and chemical content. In the context of the ALMA-DOT program,…
The Interstellar Dust Emission Spectrum, Going beyond the single temperature greybody
François-Xavier Désert
Context. Most of the modelling of interstellar dust infrared emission spectrum is done by assuming some variations around a single temperature greybody approximation. For example,…
