The cold molecular gas in contemporary galaxies is structured in discrete cloud complexes. These giant molecular clouds (GMCs), with 104–107 solar masses (M⊙) and radii of 5–100 parsecs, are the seeds of star formation1. Highlighting the molecular gas structure at such small scales in distant galaxies is observationally challenging. Only a handful of molecular clouds were reported in two extreme submillimetre galaxies at high redshift2–4. Here we search for GMCs in a typical Milky Way…

From giant clumps to clouds – I. The impact of gas fraction evolution on the stability of galactic discs
The morphology of gas-rich disc galaxies at redshift $\sim 1\!-\!3$ is dominated by a few massive clumps. The process of formation or assembly of these clumps and their relation to molecular clouds
Stellar feedback in a clumpy galaxy at z ∼ 3.4
Giant star-forming regions (clumps) are widespread features of galaxies at z ≈ 1−4. Theory predicts that they can play a crucial role in galaxy evolution, if they survive to stellar feedback for
Giant star-forming clumps?
With the spatial resolution of the Atacama Large Millimetre Array (ALMA), dusty galaxies in the distant Universe typically appear as single, compact blobs of dust emission, with a median half-light
Hierarchical fragmentation in high redshift galaxies revealed by hydrodynamical simulations
High-redshift star-forming galaxies have very different morphologies compared to nearby ones. Indeed, they are often dominated by bright star-forming structures of masses up to 108−9 M dubbed «giant
The Molecular Cloud Lifecycle
Results from observational, theoretical, and numerical work are reviewed to build a dynamical picture of the evolutionary lifecycle of GMC evolution, star formation, and feedback in galaxies.
Star cluster formation in the most extreme environments: insights from the HiPEEC survey
We present the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey. We fit HST NUV to NIR broadband and H$\alpha$ fluxes, to derive star cluster ages, masses, extinctions and
The ALPINE-ALMA [C II] survey
The molecular gas content of normal galaxies atz >  4 is poorly constrained because the commonly used molecular gas tracers become hard to detect at these high redshifts. We use the [C II] 158μm
Milky Way–like Gas Excitation in an Ultrabright Submillimeter Galaxy at z = 1.6
Based on observations with the IRAM 30 m and Yebes 40 m telescopes, we report evidence of the detection of Milky Way–like, low-excitation molecular gas, up to the transition CO(J = 5–4), in a
High-redshift star formation in the Atacama large millimetre/submillimetre array era
The main advances ALMA has helped bring about in understanding of the dust and gas properties of high-redshift (z≳1) star-forming galaxies during these first 9 years of its science operations are reviewed, and the interesting questions that may be answered by ALMA in the years to come are highlighted.

We report an ultrabright lensed submillimeter galaxy at z spec = 1.4796, identified as a result of a full-sky cross-correlation of the AllWISE and Planck compact source catalogs aimed at searching


The gravitationally unstable gas disk of a starburst galaxy 12 billion years ago
The spatial and kinematic structure of the molecular gas inside the heavily dust-obscured core and show that the underlying gas disk is clumpy and rotationally supported are resolved, suggesting that the self-gravity of the gas is stronger than the differential rotation of the disk and the internal pressure due to stellar-radiation feedback.
We resolve 182 individual giant molecular clouds (GMCs) larger than 2.5 × 10^5 M ☉ in the inner disks of 5 large nearby spiral galaxies (NGC 2403, NGC 3031, NGC 4736, NGC 4826, and NGC 6946) to

The nature of giant clumps in distant galaxies probed by the anatomy of the cosmic snake
Giant stellar clumps are ubiquitous in high-redshift galaxies1,2. They are thought to play an important role in the build-up of galactic bulges3 and as diagnostics of star formation feedback in
Cold streams in early massive hot haloes as the main mode of galaxy formation
‘stream-fed galaxies’ are reported, formed from steady, narrow, cold gas streams that penetrate the shock-heated media of massive dark matter haloes and keep the rotating disk configuration intact, although turbulent and broken into giant star-forming clumps that merge into a central spheroid.
The properties of Galactic molecular clouds tabulated by Solomon et al. (SRBY) are re-examined using the Boston University-FCRAO Galactic Ring Survey of 13CO J = 1-0 emission. These new data provide
