A High-Resolution Investigation of the Multi-Phase ISM in a Galaxy during the First Two Billion Years

S. Dye, S. A. Eales, H. L. Gomez +20

We have carried out the first spatially-resolved investigation of the multi-phase interstellar medium (ISM) at high redshift, using the z=4.24 strongly-lensed sub-millimetre galaxy…

Molecules with ALMA at Planet-forming Scales (MAPS) IV: Emission Surfaces and Vertical Distribution of Molecules

Charles J. Law, Richard Teague, Ryan A. Loomis +32

The Molecules with ALMA at Planet-forming Scales (MAPS) Large Program provides a unique opportunity to study the vertical distribution of gas, chemistry, and temperature in the pro…

Molecules with ALMA at Planet-forming Scales (MAPS) XII: Inferring the C/O and S/H ratios in Protoplanetary Disks with Sulfur Molecules

Romane Le Gal, Karin I. Öberg, Richard Teague +24

Sulfur-bearing molecules play an important role in prebiotic chemistry and planet habitability. They are also proposed probes of chemical ages, elemental C/O ratio, and grain chemi…

Disk fragmentation in high-mass star formation. High-resolution observations towards AFGL 2591-VLA 3

S. Suri, H. Beuther, C. Gieser +29

Increasing evidence suggests that, similar to their low-mass counterparts, high-mass stars form through a disk-mediated accretion process. At the same time, formation of high-mass…

Stellar structures, molecular gas, and star formation across the PHANGS sample of nearby galaxies

M. Querejeta, E. Schinnerer, S. Meidt +32

We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct morphological masks of sub-galactic environments based on Spitzer 3.6 micron images. At the…

Exploring the 100 au Scale Structure of the Protobinary System NGC 2264 CMM3 with ALMA

Yoshiki Shibayama, Yoshimasa Watanabe, Yoko Oya +8

We have observed the young protostellar system NGC 2264 CMM3 in the 1.3 mm and 2.0 mm bands at a resolution of about 0.1 (70 au) with ALMA. The structures of two distinct compon…

Dense molecular gas properties on 100 pc scales across the disc of NGC 3627

I. Bešlić, A. T. Barnes, F. Bigiel +29

It is still poorly constrained how the densest phase of the interstellar medium varies across galactic environment. A large observing time is required to recover significant emissi…

Impact of Size-dependent Grain Temperature on Gas-Grain Chemistry in Protoplanetary Disks: the case of low mass star disks

S. Gavino, A. Dutrey, V. Wakelam +7

Grain surface chemistry is key to the composition of protoplanetary disks around young stars. The temperature of grains depends on their size. We evaluate the impact of this temper…

SEEDisCS II. Molecular gas in galaxy clusters and their large scale structure: low gas fraction galaxies, the case of CL1301.71139

D. Spérone-Longin, P. Jablonka, F. Combes +8

This paper is the second of a series that tackles the properties of molecular gas in galaxies residing in clusters and their related large-scale structures. Out of 21 targeted fiel…

New Constraints on the CO(2-1)/(1-0) Line Ratio Across Nearby Disc Galaxies

J. S. den Brok, D. Chatzigiannakis, F. Bigiel +18

Both the CO(2-1) and CO(1-0) lines are used to trace the mass of molecular gas in galaxies. Translating the molecular gas mass estimates between studies using different lines requi…

Applying the Tremaine-Weinberg Method to Nearby Galaxies: Stellar Mass-Based Pattern Speeds, and Comparisons with ISM Kinematics

Thomas G. Williams, Eva Schinnerer, Eric Emsellem +22

We apply the Tremaine-Weinberg method to 19 nearby galaxies using stellar mass surface densities and velocities derived from the PHANGS-MUSE survey, to calculate (primarily bar) pa…

SEEDisCS I. Molecular gas in galaxy clusters and their large scale structure: the case of CL1411.11148 at

D. Spérone-Longin, P. Jablonka, F. Combes +7

We investigate how the galaxy reservoirs of molecular gas fuelling star formation are transformed while the host galaxies infall onto galaxy cluster cores. As part of the Spatially…
