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…

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…
