Orbital Clustering Identifies the Origins of Galactic Stellar Streams
Ana Bonaca, Rohan P. Naidu, Charlie Conroy +9
The origins of most stellar streams in the Milky Way are unknown. With improved proper motions provided by Gaia EDR3, we show that the orbits of 23 Galactic stellar streams are hig…
The survival of globular clusters in a cuspy Fornax
Shi Shao, Marius Cautun, Carlos S. Frenk +5
It has long been argued that the radial distribution of globular clusters (GCs) in the Fornax dwarf galaxy requires its dark matter halo to have a core of size kpc. We rev…
Distances to PHANGS Galaxies: New Tip of the Red Giant Branch Measurements and Adopted Distances
Gagandeep S. Anand, Janice C. Lee, Schuyler D. Van Dyk +29
PHANGS-HST is an ultraviolet-optical imaging survey of 38 spiral galaxies within ~20 Mpc. Combined with the PHANGS-ALMA, PHANGS-MUSE surveys and other multiwavelength data, the dat…
Bridging the Planet Radius Valley: Stellar Clustering as a Key Driver for Turning Sub-Neptunes into Super-Earths
J. M. Diederik Kruijssen, Steven N. Longmore, Mélanie Chevance
Extrasolar planets with sizes between that of the Earth and Neptune () have a bimodal radius distribution. This 'planet radius valley' separates com…
The Elephant in the Bathtub: when the physics of star formation regulate the baryon cycle of galaxies
Jindra Gensior, J. M. Diederik Kruijssen
In simple models of galaxy formation and evolution, star formation is solely regulated by the amount of gas present in the galaxy. However, it has recently been shown that star for…
Linking globular cluster formation at low and high redshift through the age-metallicity relation in E-MOSAICS
Danny Horta, Meghan E. Hughes, Joel L. Pfeffer +4
We set out to compare the age-metallicity relation (AMR) of massive clusters from Magellanic Cloud mass galaxies in the E-MOSAICS suite of numerical cosmological simulations with a…
ALMA Resolves Giant Molecular Clouds in a Tidal Dwarf Galaxy
M. Querejeta, F. Lelli, E. Schinnerer +12
Tidal dwarf galaxies (TDGs) are gravitationally bound condensations of gas and stars formed during galaxy interactions. Here we present multi-configuration ALMA observations of J10…
Pre-supernova feedback mechanisms drive the destruction of molecular clouds in nearby star-forming disc galaxies
Mélanie Chevance, J. M. Diederik Kruijssen, Mark R. Krumholz +28
It is a major open question which physical processes stop the accretion of gas onto giant molecular clouds (GMCs) and limit the efficiency at which gas is converted into stars with…
Stellar clustering shapes the architectures of planetary systems
Andrew J. Winter, J. M. Diederik Kruijssen, Steven N. Longmore +1
Planet formation is generally described in terms of a system containing the host star and a protoplanetary disc, of which the internal properties (e.g. mass and metallicity) determ…
The Phoenix stellar stream rose from the ashes of an ancient star cluster
J. M. Diederik Kruijssen
Observations of an ancient stellar stream provide the first evidence of a vanished population of extremely metal-poor stellar clusters. Their remnants might reveal how the early as…
Which feedback mechanisms dominate in the high-pressure environment of the Central Molecular Zone?
Ashley T. Barnes, Steven N. Longmore, James E. Dale +3
Supernovae (SNe) dominate the energy and momentum budget of stellar feedback, but the efficiency with which they couple to the interstellar medium (ISM) depends strongly on how eff…
An uncertainty principle for star formation -- V. The influence of dust extinction on star formation rate tracer lifetimes and the inferred molecular cloud lifecycle
Daniel T. Haydon, Yusuke Fujimoto, Mélanie Chevance +3
Recent observational studies aiming to quantify the molecular cloud lifecycle require the use of known 'reference time-scales' to turn the relative durations of different phases of…
Measuring the mixing scale of the ISM within nearby spiral galaxies
Kathryn Kreckel, I-Ting Ho, Guillermo A. Blanc +28
The spatial distribution of metals reflects, and can be used to constrain, the processes of chemical enrichment and mixing. Using PHANGS-MUSE optical integral field spectroscopy, w…
Star cluster formation in the most extreme environments: Insights from the HiPEEC survey
A. Adamo, K. Hollyhead, M. Messa +14
We present the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey. We fit HST NUV to NIR broadband and H fluxes, to derive star cluster ages, masses, exti…
CMZoom: Survey Overview and First Data Release
Cara Battersby, Eric Keto, Daniel Walker +19
We present an overview of the CMZoom survey and its first data release. CMZoom is the first blind, high-resolution survey of the Central Molecular Zone (CMZ; the inner 500 pc of th…
Towards a multi-tracer timeline of star formation in the LMC -- I.\ Deriving the lifetimes of H\,{\sc i} clouds
Jacob L. Ward, Mélanie Chevance, J. M. Diederik Kruijssen +3
The time-scales associated with the various stages of the star formation process remain poorly constrained. This includes the earliest phases of star formation, during which molecu…
Ubiquitous velocity fluctuations throughout the molecular interstellar medium
J. D. Henshaw, J. M. D. Kruijssen, S. N. Longmore +23
The density structure of the interstellar medium (ISM) determines where stars form and release energy, momentum, and heavy elements, driving galaxy evolution. Density variations ar…
The role of galactic dynamics in shaping the physical properties of giant molecular clouds in Milky Way-like galaxies
Sarah M. R. Jeffreson, J. M. Diederik Kruijssen, Benjamin W. Keller +2
We examine the role of the large-scale galactic-dynamical environment in setting the properties of giant molecular clouds in Milky Way-like galaxies. We perform three high-resoluti…

From diffuse gas to dense molecular cloud cores
Javier Ballesteros-Paredes, Philippe André, Patrck Hennebelle +7
