The upGREAT dual frequency heterodyne arrays for SOFIA

C. Risacher, R. Güsten, J. Stutzk +30

We present the performance of the upGREAT heterodyne array receivers on the SOFIA telescope after several years of operations. This instrument is a multi-pixel high resolution (R >…

Two Orders of Magnitude Variation in the Star Formation Efficiency Across the Pre-Merger Galaxy NGC 2276

Neven Tomicic, Annie Hughes, Kathryn Kreckel +7

We present the first spatially resolved (~0.5 kpc) measurements of the molecular gas depletion time across the disk of the interacting spiral galaxy NGC\,2276, a system…

A 50 pc scale view of star formation efficiency across NGC 628

K. Kreckel, C. Faesi, J. M. D. Kruijssen +16

Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (<kpc) and global galaxy environment. We present first results f…

First Detection of the Simplest Organic Acid in a Protoplanetary Disk

Cécile Favre, Davide Fedele, Dmitry Semenov +14

The formation of asteroids, comets and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition of th…

The Star Formation Efficiency per Free Fall Time in Nearby Galaxies

Dyas Utomo, Jiayi Sun, Adam K. Leroy +16

We estimate the star formation efficiency per gravitational free fall time, , from observations of nearby galaxies with resolution matched to the typical size of a Gian…

Chemistry in disks. XI. Sulfur-bearing species as tracers of protoplanetary disk physics and chemistry: the DM Tau case

D. Semenov, C. Favre, D. Fedele +7

Context. Several sulfur-bearing molecules are observed in the interstellar medium and in comets, in strong contrast to protoplanetary disks where only CS, HCS and SO have been…

The search for high-mass protostars with ALMA revealed up to kilo-parsec scales (SPARKS): I. Indication for a centrifugal barrier in the environment of a single high-mass envelope

T. Csengeri, S. Bontemps, F. Wyrowski +11

The formation of the most massive O-type stars is poorly understood. We present a case study of a young massive clump from the ATLASGAL survey, G328.2551-0.5321. It exhibits a bolo…

Astrochemical evolution along star formation: Overview of the IRAM Large Program ASAI

B. Lefloch, R. Bachiller, C. Ceccarelli +27

Evidence is mounting that the small bodies of our Solar System, such as comets and asteroids, have at least partially inherited their chemical composition from the first phases of…
